Andriamanitra: we can't see the solutions or the problem

Andriamanitra: but i wouldn't worry about the results that much, it's all in good fun

Andriamanitra: you can always learn ruby or perl if you want to have revenge on the javascripters :p

Default avatar.png Ajay-Bisht.7017.: hi what up

likki1811: are you a learner? or a professional?

ProCoder3: Can someone help me with Crystal rush , I am confused about how to make it dig

ProCoder3: can anyone give a gist of idea on how to do it

ProCoder3: ???

ProCoder3: thanks

AntiSquid: see statement

AntiSquid: just dig

AntiSquid: DIG

ProCoder3: Thanks @AntiSquad

Andriamanitra: anyone got some pro tips for debugging "unfolding paper" puzzle

Andriamanitra: all the simple test cases i can think of pass but i have some bugs in the big ones

Andriamanitra: ah, found it

Default avatar.png Gargaz: How do I figure out why my syntax is invalid

Andriamanitra: depending on the language the error messages may be helpful

Default avatar.png Gargaz: It's python

Default avatar.png Gargaz: Psuedo code algorithm gives very vague help

Andriamanitra: are you getting any error message, maybe a line number?

Default avatar.png Gargaz: SyntaxError: invalid syntax at Answer.py. not in a function on line 24

Andriamanitra: did you try to do something that you can only do inside a function?

Andriamanitra: or maybe you forgot a colon somewhere?

Default avatar.png Gargaz: Not sure, first two levels was easy enough to just edit the values in the code now I have to do a function I have no idea on how to do

Default avatar.png bigfatnoob: guys how dou you increase thrust on coders strike back

Default avatar.png Gargaz: edit the value

Default avatar.png bigfatnoob: how

Default avatar.png Gargaz: by changing it from 50 to 100

Default avatar.png Gargaz: in the code

Default avatar.png Gargaz: So... now I got the working if statement I think, but the "end if" satement returns a syntax error invalid syntax

Andriamanitra: there is no end if in python

jacek: python is eternal

Andriamanitra: you should probably look up some beginner guide on python and go through the first section to get a feel for the syntax.. it's all indentation based, no "end"s or "}"s

Default avatar.png Gargaz: Fair enough, I did however think this was for beginners

Andriamanitra: well, yes, but you need to know some basics

Default avatar.png Gargaz: Got an error now on a line I dont have

Default avatar.png Gargaz: SyntaxError: unexpected EOF while parsing at Answer.py. not in a function on line 28

Default avatar.png Gargaz: My code has 26 lines

Default avatar.png bigfatnoob: it just instantly ends as soon as i press start

Default avatar.png George012GR: hey how do i learn c#

MSmits: many ways to do that. I learned it while scripting and modding for space engineers (a game)

Default avatar.png Community-Bot: hii everyone

Default avatar.png George012GR: thankis but where do i start learning about c#

sh4shI: hell yey

Default avatar.png Rouli: can anyone help me with this : http://chat.codingame.com/pastebin/b09d28a6-e8cc-44b5-a0ce-1aed6dbc0f4b

Andriamanitra: looks like you're off to a good start, although the indentation is giving me nightmares

Andriamanitra: you'll need to handle the edge case where there's negative and positive temperature equally close to zero though

MSmits: nightmare on indentation street

Default avatar.png Rouli: so you mean adding if statement like this ( if t>=0 and t<0) , right?

Default avatar.png Rouli: Indentation because there's a loop code above :sweat_smile:

Default avatar.png bigfatnoob: i cant do this bronze league level what is the code for it

AntiSquid: "this"

AntiSquid: which game ?

Default avatar.png Rouli: analyze records of temperature to find the closest to zero.

Default avatar.png Community-Bot: who nice game

Default avatar.png bigfatnoob: coders strike back

AntiSquid: -3 velocity

Default avatar.png Community-Bot: u can't borrow code from other hiledhuwsj

AntiSquid: you can add -3*velocity

Default avatar.png bigfatnoob: but it like just ends intantly

AntiSquid: hiledhuwsj it only gets harder not easier

AntiSquid: that means you have a bug ! fix the bug

Default avatar.png bigfatnoob: how

AntiSquid: by reading the code ? undoing the bugs you added ?

Default avatar.png bigfatnoob: i reset the code

AntiSquid: or go to HISTORY and look at your previous submit and start over from there

Andriamanitra: @Rouli "t>=0 and t<0" is always false, t can't be both greater than or equal to zero and less than zero at the same time!

jacek: whats Community-Bot? :o o: :o

Westicles: He's come to help us with our problems, so he can be free

Default avatar.png bigfatnoob: my cars are not moving in coders strike back

jacek: no fuel?

darkhorse64: no thrust ? no destination ?

jacek: no purpose in life

Default avatar.png Rockstar555-tech: hii

sikr_: hello

AntiSquid: hii

Default avatar.png GiorgosGiorgakis: why cant I progress in coders strike back

AntiSquid: rank too low or submit isn't finished

Default avatar.png GiorgosGiorgakis: why does this always evaluates to true if( (done == 0) && (nextCheckpointDist == maxdist) && (runs>3) ){

   cout << nextCheckpointX << " " << nextCheckpointY << " " << "BOOST" << endl;
   done = 1;
   }

Default avatar.png GiorgosGiorgakis: wheres the debugger

jacek: cerr

Default avatar.png mARIO-san: Failure Found: lets dance Expected: lets dance hmm

jacek: space in the end?

Default avatar.png mARIO-san: nope i checked

jacek: did they expect the hmm?

Default avatar.png mARIO-san: the hmm was me pondering

Default avatar.png mARIO-san: Failure Found: lets dance Expected: lets dance

Default avatar.png Codin.Gamer: hii everyone whatsup

Default avatar.png GiorgosGiorgakis: I beat the boss in coders strike back back I cant advance the leagues

Default avatar.png mARIO-san: figured it out. It didnt like that i was printing chars but he expected a single string

AntiSquid: GiorgosGiorgakis and you have a complete submit ?

Default avatar.png GiorgosGiorgakis: yes that was the problem

Default avatar.png GiorgosGiorgakis: now im rank 1 itll probably advance now

Default avatar.png GiorgosGiorgakis: I have only the button test in arena

Default avatar.png GiorgosGiorgakis: nah still wood

Default avatar.png GiorgosGiorgakis: :D

AntiSquid: did you just resubmit ?

Default avatar.png GiorgosGiorgakis: I only have the button TEST IN ARENA

AntiSquid: so the answer is yes

Default avatar.png GiorgosGiorgakis: yes I pressed it again :o

AntiSquid: and then you complain you can't advance :D

Default avatar.png GiorgosGiorgakis: does it advance on it's own?

Default avatar.png GiorgosGiorgakis: I went to rank 1 but it didnt advance

AntiSquid: in the IDE click leaderboard and read text at the top

AntiSquid: or maybe it doesn't show anymore when you get promoted, anyway you need a complete submit

Default avatar.png GiorgosGiorgakis: so submit = test in arena button

AntiSquid: you should see something like "those better than the boss will be promoted at ..."

AntiSquid: and that only happens at 100% submit, so just wait ?

Default avatar.png GiorgosGiorgakis: ok it advanced now

Default avatar.png GiorgosGiorgakis: i have a laggy laptop

Default avatar.png GiorgosGiorgakis: :v:

AntiSquid: :boom:

Default avatar.png TySon2: hii i am new to codingame any body tell me about it

bigfatnoob: ive won finnaly

Kitkat260: morning

Wontonimo: morning

Kitkat260: hru

Wontonimo: and good afternoon to my euro friends

Kitkat260: wru from?

Wontonimo: my mother. you?

Kitkat260: NYC

baguettes: wat dat

Wontonimo: it's the place where NYCF comes froms

Kitkat260: new york city

Wontonimo: the big apple

Default avatar.png oohIsniffcpp: lol it's night here

Kitkat260: nice

AntiSquid: starry sky ?

Kitkat260: anyone want to be code buddies

Wontonimo: how so?

Default avatar.png oohIsniffcpp: cloudy.

Kitkat260: cause i'm lonely

Wontonimo: is there a coding challenge or a bot competition you are working on?

Wontonimo: (on this site)

Kitkat260: yes

Kitkat260: clash of code

jacek: is it :notebook: :soccer:

Kitkat260: @jacek hi

jacek: good afternoon, Sir/Madam

Wontonimo: Kitkat260 I'm tired of CoC. If you want to take a look at some of the practice or compete items, I'd be happy to help if you get stuck on one

Kitkat260: ok

Kitkat260: @and i'm a gal

Wontonimo: In practice, the easy puzzles will take a lot longer than the CoC. CoC is designed to be about a max of 15 min per puzzle. The easy puzzles will take you a lot longer each. If you find CoC challenging, then they could take a few hours each.

Kitkat260: ok

Wontonimo: The first practice puzzle I recommend to everyone is https://www.codingame.com/training/easy/mars-lander-episode-1 I found it really fun when i started and it got me hooked

Kitkat260: plz join

Kitkat260: https://www.codingame.com/clashofcode/clash/1609047769cbd27452f8a4bf63bc302f7243683

MSmits: no clash link here

Wontonimo: ^ there's a channel on discord for those

MSmits: #clash

Wontonimo: ^

Kitkat260: im on a school chromebook

MSmits: sorry to hear that

Kitkat260: and.....

MSmits: thats it

Kitkat260: ok

Kitkat260: can u join soo i can get help

MSmits: sorry, i dont clash

Wontonimo: i've been meaning to pick up a chromebook for a while... the thought of portability, chrominess, and then I remember I don't leave my desk ever

AntiSquid: that's why we don't have clash links here, not everyone enjoys clash but some people will spam the link until others join (never)

Wontonimo: i mean, why do i even work on a laptop when I sit here for 14 hours a day?

MSmits: i dont like the idea of only being dependend on chrome addons

MSmits: dependent

MSmits: also its bad for your back/neck to stare downwards for hours

Kitkat260: nvm

Wontonimo: (that sounds like the beginning of a joke)

Default avatar.png ratasorin: i am a pro fortnite player

Default avatar.png ratasorin: lmao

MSmits: think i missed the punchline

Kitkat260: hi

AntiSquid: maybe fortnite is the joke ?

Default avatar.png ratasorin: = 0lmao no

Wontonimo: MSmits its bad for your back/neck to stare downwards for hours... that's what ___ said?

Default avatar.png ratasorin: lmao

Kitkat260: no

AntiSquid: too many lmao per second

Default avatar.png ratasorin: lmao

MSmits: you measured it?

Kitkat260: ratasorin want to be my friend

Wontonimo: stop it MSmits !

Wontonimo: omg

MSmits: i was referring to AntiSquid :P

Default avatar.png ratasorin: i love daddy

AntiSquid: 4 in one minute, so 0.2

Default avatar.png ratasorin: lmao

Default avatar.png ratasorin: make that more

AntiSquid: 0.05 sorry

Default avatar.png ratasorin: lmaooo

Kitkat260: hello

AntiSquid: nvm ... wrong again, too distracted T_T

Kitkat260: i'm lonely

Wontonimo: so, i didn't convince you to drop your CoC addiction Kitkat260 ?

MSmits: you can easily code a calculator in python AntiSquid. I did this with my students

AntiSquid: didn't sleep enough i think

RAWAN_REDDY: can some1 help me with binary problem

Wontonimo: link?

RAWAN_REDDY: to find if a number has zeroes in bin representation

RAWAN_REDDY: https://www.codingame.com/clashofcode/clash/report/1609038cbbb8d37da0ef9342295307e35da02b1

MSmits: problem = 1. problem ^= 1 -> problem = 0

RAWAN_REDDY: how do i share the problem here

Default avatar.png DJSchaffner: check if the number & however many bits you have set to one equals to zero or not

Kitkat260: ok @wontonimo

RAWAN_REDDY: some help me understand this pls

AntiSquid: you should do coc on your own

Wontonimo: it looks like it is complete and done.

RAWAN_REDDY: its over just trying to understand others solution

AntiSquid: screenshot the statement i guess ?

RAWAN_REDDY: print(str(-~a&a==0).lower())

RAWAN_REDDY: what does this do

struct: a = 5

struct: str(6&5==0)

struct: .lower()

RAWAN_REDDY: ok i see & work bit wise

RAWAN_REDDY: what is this '-~'

struct: -~5 = 6

struct: ~-5 = 4

struct: it increases number by one

RAWAN_REDDY: ` reverses

RAWAN_REDDY: - is subtraction

RAWAN_REDDY: meaning

AntiSquid: is it this ? https://www.tutorialspoint.com/What-is-tilde-operator-in-Python

RAWAN_REDDY: i got reverses

RAWAN_REDDY: ok thank you guys

RAWAN_REDDY: gr8 got it

Default avatar.png DJSchaffner: oh wow i was wondering if i was blind but the font here just seems to mess up the tilde for me

RAWAN_REDDY: yea it does

RAWAN_REDDY: i was think the same

AntiSquid: you need large screen, works fine for me :P

RAWAN_REDDY: lol

AntiSquid: had same issue on smaller screens

struct: nah

struct: its font related

AntiSquid: oh ok

Wontonimo: For example >>> [ -~x&x for x in range(10) ] [0, 0, 2, 0, 4, 4, 6, 0, 8, 8]

Wontonimo: (oh, sorry, coversation moved on)

AntiSquid: why the .lower() ?

RAWAN_REDDY: actually i still didnt get it

RAWAN_REDDY: lower is part of question dont worry about it

Wontonimo: i think the answer needed "true" or "false" , but [ -~x&x==0 for x in range(10) ] [True, True, False, True, False, False, False, True, False, False] returns camel case

AntiSquid: ah ok just checked

Kitkat260: /me

AntiSquid: RAWAN_REDDY check the link i shared earlier

Wontonimo: i'll have to remember "-~x" for golf

RAWAN_REDDY: yeah am trying to figure compliment

Kitkat260: is anyone lonely or is it just me

AntiSquid: look up bit representation then i guess

RAWAN_REDDY: yea at it rn

Default avatar.png DJSchaffner: why not use +1 / -1 though? first time i see this and trying to understand the reason. the order of execution should even be the same and its more clear what it does

Wontonimo: that's code golf for you. readability isn't the point

Default avatar.png DJSchaffner: yeah but a+1 is the same length as -~a

AntiSquid: less magical

Default avatar.png DJSchaffner: i mean if it did actually shorten the statement i would understand

Wontonimo: your words are true, both of you

RoboStac: there are cases where operator precedence makes -~ shorter (eg doubling x+1 needs (x+1)*2 as opposed to -~x*2) so maybe whoever it was just always does -~x to increment

RAWAN_REDDY: wow

RAWAN_REDDY: nice

RAWAN_REDDY: thanks

Wontonimo: don't put that in any real code, just saying. golf only

baguettes: UBODMAS or UPEMDAS for programming ;)

baguettes: U for unary

Grizzlyslayer: sup ppl

struct: it is interesting how it works

struct: ~5 flips the bits and becomes -6

struct: - -6 becomes 6

Andriamanitra: how do you even write javascript with a broken numpad if you're not allowed to do -~-~-~-~-~null

Andriamanitra: it's also nice because you don't need to remember what the numbers look like you can just type -~ every time you want one more

Kitkat260: anyone good at history

Wontonimo: MSmits that refactoring was a pain. Now just double check nothing broke (no change in sim/sec yet), and now it's time to refactor for static allocation of nodes.

jacek: you use nodes pool now?

Default avatar.png UnnamedCodinGamer: I am thinking of making a mcts playground on tech.io. I have implemented it on ordinary tic tac toe with simple to read code

Default avatar.png UnnamedCodinGamer: does that make any sense?

MSmits: yeah it can be a lot of work to refactor an 1k line bot

MSmits: try a 2k line bot, even worse :P

jacek: plot twist: 2k line python bot

MSmits: ugh

MSmits: I can imagine that

MSmits: line 663.... now was this an integer or a float ?

Default avatar.png UnnamedCodinGamer: The idea is to test and play around with the algorithm

MSmits: who renamed automaton?

MSmits: oh i missed your earlier message

MSmits: seemed out of the blue

MSmits: sure, mcts playground is good, but i think it exists already

Default avatar.png UnnamedCodinGamer: does it?

MSmits: i think euler wrote one? Or someone else

MSmits: yeah

Default avatar.png UnnamedCodinGamer: I did not find it on tech.io

struct: its just a code snippet

struct: not a playground

Valdez001: good morning

MSmits: oh ok

struct: hi

Default avatar.png UnnamedCodinGamer: yes, I have seen it and could not make much sense of it

MSmits: well you can always make a better one UnnamedCodinGamer

MSmits: it would nice to have

MSmits: be

jacek: nice to be?

struct: nice to have be

Default avatar.png UnnamedCodinGamer: I recently managed to implement mcts and to get it to work as expected

MSmits: it would be nice to have :P

Default avatar.png UnnamedCodinGamer: then I returned to a previous attempt where I tried it with tic tac toe

Default avatar.png UnnamedCodinGamer: now it works

struct: Add solver to it :)

Default avatar.png UnnamedCodinGamer: and just wanted to share it, so that others have an example

Astrobytes: Seems like a good idea. A lot of people ask about it here in chat

Default avatar.png UnnamedCodinGamer: yes

Default avatar.png UnnamedCodinGamer: I think just reading from different sources it can be confusing

Default avatar.png UnnamedCodinGamer: for me it was

Astrobytes: It's easier for us to give help in optimising it if people already understand the algo.

Astrobytes: And yes, I was the same initially.

Default avatar.png UnnamedCodinGamer: yes, definately

MSmits: very true

Astrobytes: Is there an article on MCTS solver? Did jacek cover that in his one?

N-ONE: how to study for college and improve yourself in the field ? anyone knows how ? i am sick of college stuff

Default avatar.png UnnamedCodinGamer: there are articles

jacek: i didnt do anything for solver

jacek: and a paper

Astrobytes: oh it was meta MCTS

Astrobytes: Yeah I know there are papers, I meant on tech.io

jacek: jacekmax has implied solver

Default avatar.png UnnamedCodinGamer: but they did not give you the implementation details

Default avatar.png UnnamedCodinGamer: I think where I was wrong was for instance how to treat end game nodes

Astrobytes: afk for a bit, bbl

Default avatar.png UnnamedCodinGamer: https://tech.io/snippet/2oI54uz

Default avatar.png UnnamedCodinGamer: is this understandable enough?

struct: A bit different from my code

struct: I dont store state

struct: or uct value on nodes

Default avatar.png UnnamedCodinGamer: yes, it is something like proof of concept code

Default avatar.png UnnamedCodinGamer: it can be optimized a lot

Default avatar.png UnnamedCodinGamer: the idea is to see how it works

Default avatar.png UnnamedCodinGamer: to check node visit counts

Default avatar.png UnnamedCodinGamer: play with the number of iterations

Default avatar.png CMIKAIL: (__)

Kitkat260: hi

Default avatar.png Jaminima: bonjour

Wontonimo: jacek "you use nodes pool now?" Just implemented it minutes ago. No performance change yet :(

jacek: should be easier to reuse tree now

Wontonimo: true, and I'm excited to implement the tree reuse... just a little sad that after all that refactoring and memory savings, the benefits were eaten up with board calculations

Wontonimo: ah, all my hyperparameters were tuned for the old architecture ... gotta retune

jacek: *5 years later*

MasterCoderxD: https://www.codingame.com/clashofcode/clash/1609299236fc7e6ee4be9171a25aea2211cd7a8

MasterCoderxD: #clash

Wontonimo: yeah, it sure feels like 5 years, but fortunately it only takes about 1 hour.

Kitkat260: hi

reCurse: Wontonimo: You are always bound by your weakest link, sometimes the right steps only pay off later when you fix some of the others.

jacek: teach us sensei

Wontonimo: reCurse words of wisdom for sure

Wontonimo: also, i'm looking forward to porting the tree reuse and solver from my c++ to my gMCTS npm package once it's done an proves itself

jacek: gMCTS?

jacek: npm? :scream:

-oa-: i

-oa-: ^ supposed to go to insert mode in editor, sorri for spam

jacek: oO

Wontonimo: you no like npm jacek ?

brandonFaf: If there was a coding problem that i didn't get to finish and i wanted to keep trying it locally, is there a way to find the prompt/tests to do that?

jacek: sounds like js

Wontonimo: brandonFaf not something that is directly supported within CG.

reCurse: Isn't there a euler tool for that

Wontonimo: if you know the name of the clash, you can look it up with the tool

Wontonimo: https://eulerschezahl.herokuapp.com/codingame/puzzles/

brandonFaf: dang i didn't think to look at the name, i just have the id of the clash. Thats still helpful though. Thanks

Astrobytes: you can search by keywords you remember from the description of the problem too

Toby75: A question - why does my RegEx in JS apply to all occurences in a string, even though it ist not using a global flag??

Toby75: I tested it on another ide and it worked perfectly

Wontonimo: show code of each test plz

Toby75: https://www.codingame.com/ide/demo/873805aa9f16bc6eb2a53fdd8753ad5e22c8ca

Toby75: Code ist here: https://pastebin.com/NFHtbnN1

Toby75: please just lmk if someone knows why it replaces every single zero even though there is no global flag

Wontonimo: the pastebin link is blocked for me for security reasons

jacek: http://chat.codingame.com/pastebin/fb586c6c-9ebb-423d-843e-2f8440fc885b

jacek: maybe they are protecting you from js insanity

reCurse: Well you ask it to match between 1 and 3 zeros greedily

Toby75: i have really no idea, regex ist confusing me again

reCurse: Do you have a specific test case

Toby75: reCurse yeah - but it should replace the first one to three zeros in a block

Toby75: it even replaces the zeros that are in the center of the block

Toby75: but normaly it should not do that - it ist not using a global flag for the expression

reCurse: But you loop over the blocks? I don't get it

Toby75: I loop over every block, and the purpose of the regex ist to replace the first one to three zeros

Toby75: but if the block does not start with a zero, it should do nothing

reCurse: Yeah but you didn't tell it that

reCurse: You just said match any sequence of 1 to 3 zeros greedily

reCurse: Well, the first one it finds

reCurse: But you did not specify start of string

Toby75: no - then I would need /g at the end

reCurse: Sorry I worded badly

reCurse: It matches the first sequence of 1 to 3 zeros greedily

reCurse: But you didn't say start of string

Toby75: yeah starting from the begining of the string

reCurse: So it will pick the first one it finds anywhere in the string from the start

reCurse: You didn't specify start of string, again

reCurse: That would be /^[0]{1,3}/

Toby75: I thought it always starts at the begining of the string when there ist no /g flag

reCurse: Use regex101.com to help

reCurse: No, g flag only means it will match many times

reCurse: Means nothing about start of string, that's what ^ is for

Toby75: aight thank you

reCurse: :+1:

Toby75: still kinda weird because it used to work on my local node

Toby75: so i thought it had a problem with node version or something like that

Wontonimo: regex is super powerful and available in lots of programming languages! I think it is under appreciated. For sure any skill you gain with it will help you in other langs

reCurse: *visible restraint*

Wontonimo: come on reCurse ... i wanna hear it

reCurse: Nah don't get me started

reCurse: Have a meeting soon anyway

Wontonimo: IM TRYING !

jacek: so a programmer had a problem...

Kitkat260: hi

Wontonimo: hi again Kitkat260, you try mars lander?

Wontonimo: also https://www.codingame.com/multiplayer/bot-programming/coders-strike-back is fun and fairly easy to get started on

BlaiseEbuth: Hey there! I've a contribution in validation since some time, and considering the amount of pending CoC, and the propensity of a lot of people (including me) to flee away from this section of the site, I fear my poor puzzle could wait for a long time to be validated... So come test it ! https://www.codingame.com/contribute/view/604871ef9e9b4cf2bd697ae702e34b37c792

jacek: youre feeling?

Wontonimo: oh, i remember reading this one and thinking about it

Marchete: you still have 12 days left to validate :)

jacek: too long; didn't read lol

BlaiseEbuth: "Be long enough to make flee people unable to read and gather informations." Check.

jacek: im from instant gratification generation

jacek: make this puzzle selfsolvable

BlaiseEbuth: I'm against people who does not read puzzle's statement and wonder why their code does not pass the tests. This puzzle is designed to make them suffer.

jacek: anticeg puzzle?

Wontonimo: haha. Also, it's classified as hard, so I personally think having a long problem statement is okay. time reading it vs time solving the problem isn't out of proportion

Default avatar.png Jstn123: hi

Default avatar.png Tusuke: a

Default avatar.png Aidanr: im new to coding so im not quite good anyone explain to me?


Default avatar.png Dom9543: can someone help me with the tic tac toe AI code, i did the first two bits but when i add a third one, it displays an error. pls help

Wontonimo: first two bits ?

Default avatar.png Dom9543: line of code

Default avatar.png Aidanr: im tryna kill all the enemies in c# but i can't figure out how to kill them all?


Wontonimo: Aidanr are you talking about the onboarding puzzle?

jrke: Aidanr which game?

Default avatar.png Aidanr: Onboarding ye

jrke: thats tutorial

Default avatar.png Aidanr: ik im new

jrke: just print position of nearest enemy from you

Wontonimo: restart it and read the help text, it's very helpful

Default avatar.png Aidanr: im doing c# it wants me to shoot them all i think

Default avatar.png Aidanr: ok thanks

jacek: once per loop

Wontonimo: don't over think it

Default avatar.png Aidanr: ok thank you

Wontonimo: Dom9543 i'm guessing you just started ultimate tic tac toe, or is it another puzzle?

jacek: another uttt victim

Default avatar.png Dom9543: no i quited that one

Default avatar.png Dom9543: im solving a new one

jrke: which one?

Wontonimo: winners never quit, and quitters never win, but those who never quit and never win are idiots

Default avatar.png Dom9543: no i dont need help thank you

Wontonimo: right now i'm in the idiot camp of uttt it seems

kovi: you won!

kovi: (tomino)

kovi: tonimo sorry

jacek: :drum:

Default avatar.png Dom9543: when i have more knowlage of AI coding i will come back to that

Wontonimo: haha

Wontonimo: i like it!

Default avatar.png Jstn123: me too

Wontonimo: the MCTS solver looks really straight forward. Am i missing something? It's almost obvious (in hindsight o/c). Did anyone run into a gotcha while implementing it?

jacek: it is straightforward. just the paper is rather messy

jacek: maybe draws can be tricky

Notgoodatcoding5: Hi

Notgoodatcoding5: How is everyone?

JohnathanBarbee: I'm in the process of trying to implement it now to my bot in UTTT. I'm trying to roll my own method without copy-pasting and I've been debugging for about a week and a half now.

jacek: new craze for uttt eh

JohnathanBarbee: I found it about a month ago and it's pretty fun

Wontonimo: are you writing unit tests JohnathanBarbee ?

JohnathanBarbee: I'm going through each section and unit testing now. Right now I have a huge bug where the solver takes more than 81 turns and still, doesn't have a game fully played. I'm trying to figure out how that's possible

Wontonimo: i've got about x2 the number of lines of unit tests than actual uttt code

JohnathanBarbee: I bet so. I wish we had breakpoints so I could analyze each step in the loop

Wontonimo: oh, what? how is the solver anything other than no turns?

Wontonimo: what does your solver do?

JohnathanBarbee: I think it's either incorrectly labeling moves or repeating moves. Not sure which one

Wontonimo: is your solver doing minimax or something? my plan is to just use mcts with infinities in nodes

JohnathanBarbee: I did have my own custom method to break into Gold. Now I'm rewriting everything to use MCTS.

JohnathanBarbee: First time using MCTS and first time using BitVector32 in C#, so I knew it was an uphill battle at first.

Wontonimo: ah. Similar, I started with python and a custom MCTS-ish-thing to get to silver, then rewrote

Wontonimo: have you profiled/instrumented your code locally?

JohnathanBarbee: No. I don't want to have to write a test environment, but I thought about doing it one weekend

Wontonimo: no test environment needed! (well not much anyway). For instrumentation I hardcoded the first move to -1 -1 and set the time allowed to 10 seconds then quit after. During that time, i open up instrumentation and BAMB! you get a fabulous breakdown of where you are spending cpu time

jacek: i.e. for calculating log for every children

Wontonimo: yeah, i was calculating log for every child (but I missed that one and had to be told)

Kitkat260: suup

Astrobytes: Could you possibly expand your vocabulary from variations of 'sup' and 'hi'

JohnathanBarbee: You've convinced me to test locally. I guess I know what I'm doing tonight!

jacek: eeyup

struct: Aye

Kitkat260: hi Johnathan

JohnathanBarbee: Hey

Kitkat260: hru

Astrobytes: Sometimes I really hate this webchat, laters

Kitkat260: why

Wontonimo: good luck JohnathanBarbee, let me know how it goes

Kitkat260: Does anyone want to be friends with me?

jacek: friendship is magic

Kitkat260: how

Wontonimo: JohnathanBarbee here's my python test harness code https://gist.github.com/panchishin/14fd14e57b517528fbc4a52f1167d2de

Wontonimo: I reused by uttt code to make a "check_winner" which uses all the same logic but instead of outputting a move, it outputs "WINNER IS 1" or 2, or "UNDECIDED"

Default avatar.png tridvajedan: should i switch from java to pythom

Default avatar.png tridvajedan: n*

struct: or you can use brutal tester

struct: https://github.com/dreignier/cg-brutaltester

struct: depends on what you are trying to do

Wontonimo: oh, if only i knew of that 2 weeks ago

struct: you can still use I guess

struct: you can even run multiple games at once

Wontonimo: don't use mine, use brutaltester. Just read through it, it's way better.

Default avatar.png Hamgi: how are you guys doiiiiing !!!!!

Kitkat260: hi!!!!

Kitkat260: hru

Default avatar.png Hamgi: good just listening to some deep house music

Kitkat260: nice

jacek: deep learning house music?

Default avatar.png Hamgi: no just normal deep house

Default avatar.png Hamgi: here it is : https://www.youtube.com/watch?v=XlVd82QgACg

Kitkat260: @Hamgi want to be friends?

Default avatar.png Hamgi: sure why not

Kitkat260: nice

Kitkat260: check ur msg

jacek: oO

Wontonimo: Ôo

Kitkat260: really

Wontonimo: Poll time - which bot battle did you have the most fun with (I'm looking for a recommendation for my March focus)? Tron Battle , Spring Challenge 2020 , Great Escape , Poker Chip Race , These ones are nos

jacek: breakthrough :?

Kitkat260: goood night

PatrickMcGinnisII: Ghost in the Cell

Wontonimo: i thought breakthrough was coming ... yeah, i love the simplicity of the rules

struct: CSB

jacek: yinsh :v

Wontonimo: did you enjoy CSB more than other games struct ?

PatrickMcGinnisII: struct didn't say yinsh, lol

Astrobytes: never mind that, jacek didn't say paper soccer

jacek: rock football

struct: I enjoyed it, also you can learn some new stuff on it

struct: I learned avx by trying it on CSB

Astrobytes: scissor snooker

struct: I never recommend Yinsh

Wontonimo: good point

struct: PCR is fun, but is harder imo

struct: to create a decent sim

struct: or you can try FB

struct: which is the best multi here

Astrobytes: Is that official? :)

struct: Fantastic Bits

struct: imo its the best

struct: Dont think we will ever see another physics contest

Astrobytes: Maybe not even another contest as we know them . . .

jacek: phew

PatrickMcGinnisII: FB is good for method overloading, polymorphism ... which is still a difficult concept for me

Astrobytes: Such a C programmer :P

jacek: no polymorphism in php?

Wontonimo: not just regular morphism, poly-morphin

Astrobytes: He's a Mighty Poly-Morphism Stranger

PatrickMcGinnisII: there are ways, but inline defs aren't really a php thing

PatrickMcGinnisII: stranger ... tx god I'm not a BDSM ranger

Astrobytes: Heh heh!

PatrickMcGinnisII: tron is easy to get legend in, but watching GitC games makes it the most fun for me

Default avatar.png Jstn123: hi

Wontonimo: i have yet seen a legit good use of polymorphism other than as an example of what not to do

Astrobytes: Most of the games are fun tbh, it's worth just going through them and seeing what sticks

Astrobytes: As it's highly subjective as to which is best/most fun

PatrickMcGinnisII: Yinsh kills my brain on so many levels

Wontonimo: oh ... sorry ... i don't know why i was thinking multiple inheritance ... totally different rant. poly your morphs all you want

Astrobytes: something something deadly diamonds

Wontonimo: maybe daydrinking is not for me

Astrobytes: Your pished?

Astrobytes: *You're

Wontonimo: if i was, at least i'd have an excuse for mixing oo terms i use on the daily for 20 years. sigh... hands type faster than the brain somethings

Astrobytes: :D

Astrobytes: We're only human

PatrickMcGinnisII: COIF may be good for day drinking

PatrickMcGinnisII: ;)

Wontonimo: i'm a bit tired of CSB. I started on CG without really knowing how hardcore you people get on some games and didn't bother coding locally for the first couple months. So, although I never wrote anything serious for CSB, it feels tired to me. but you make a good point struct

Astrobytes: It's one of those things you go back to, imo

PatrickMcGinnisII: wth is PCR?

Astrobytes: Poker Chip Race

MSmits: Wontonimo, you say "you guys" but the people who get "hardcore" on games are a very small subset

MSmits: they're just overrepresented on worldchat

PatrickMcGinnisII: ahh yes, I didn't enjoy PCR

Astrobytes: 5% some say...

MSmits: I did, besides the extreme amount of coding of the sim

MSmits: if the game was easier to sim, it would be better

PatrickMcGinnisII: smitsimax bloomed on CSB i believe

MSmits: also PCR

MSmits: out of top 4, 3 are smitsimax

MSmits: including nr 1 i think

Wontonimo: hey, MSmits, have you heard of smitsimax?

MSmits: yes

Wontonimo: hahaha

Wontonimo: ;)

MSmits: i wish i thought of a more descriptive name though :P

MSmits: I was just trying to be funny during the contest where i first used the algo

Wontonimo: too late

MSmits: yup

Astrobytes: was that Kutulu?

MSmits: yeah

Astrobytes: man, that seems like decades ago

MSmits: it does

Astrobytes: It's that CG time dilation again

MSmits: I have mixed feelings though. I liked the contests, but they were also very stressful for me, i preferred the downtime between contests actually

MSmits: then i could take my time with some multi

Astrobytes: That's simply because you can't resist going all-in

MSmits: correct

Wontonimo: This one coming will be my virgin contest event. i booked time off work and everything

Wontonimo: don't let me down

MSmits: thats what i did

MSmits: made sure all my work was done as far as that was possible

MSmits: sometimes it jusr wasnt, especially when the contest happened during exam week

MSmits: that ice and fire contest, i only coded half the week and promoted legend at the end of sunday, midnight, 10 hrs before end of contest

Astrobytes: I suppose it's easier to take time of now it's only 2 per year, whether it's worth it now remains to be seen

MSmits: my submit went all the way to rank 17... never been happier in a contest

Astrobytes: *off

MSmits: well i cant actually take time off, its more shifting work around

Astrobytes: Sure you did something similar in another contest too

MSmits: i cant shift it for more than a week or 2, so it doesnt matter for me

MSmits: yeah

MSmits: ooc

MSmits: i was bored with the contest, went away for weeks

MSmits: then had a sprint in final weekend

Astrobytes: Right enough

MSmits: i think i was somewhere top 40

Astrobytes: It was long though, a month?

MSmits: yeah

MSmits: with locam i took it much more seriously

MSmits: went all in for 4 weeks, but after 2 weeks i did not get much improvement

MSmits: even kept coding on vacation, trying things

Astrobytes: yeah, in the hotel lobby or something iirc

MSmits: under the blankets, hotel room dark except for that light spot in the middle, me and my laptop operating cg bench

MSmits: that too

Astrobytes: lol, under the blankets like a child reading books by torchlight

MSmits: exactly

Astrobytes: I was one of those kids lol

Wontonimo: so ... Tron is easy to get legend. CSB is different (read NNs). Fantastic Bits is where to find them. PRC is hard but fun.

MSmits: last time i was on vacation i was obsessed with othello, the one before that i was doing puzzles to learn python, seems i am always coding

MSmits: Wontonimo please help me reach legend with tron :P

MSmits: still havent

Astrobytes: Hence the CS training ;)

Astrobytes: re. seems i am always coding

MSmits: yeah

Wontonimo: MSmits that's back to the metagame challenge : play in a league for the purpose of promoting others and making sure you dont

MSmits: ah right

Astrobytes: I might need to find a new career myself, the pharma regulatory is not good for me here now

darkhorse64: MSmits: Tron legend is 80 lines of Python

MSmits: how so

Wontonimo: i kinda would like to be able to revert back to previous leagues if i choose too

MSmits: yeah i think i did something wrong darkhorse64

struct: FB legend is <100 lines of code

Astrobytes: PI businesses are having to move to EU to get anything done

MSmits: i have a 14 depth minimax

MSmits: still gold

darkhorse64: I have a depth 1

MSmits: Astrobytes that sucks

Astrobytes: Brexit for ya

MSmits: ah yea

darkhorse64: FB legend under 100 LOC ! Wow ! Only ifs. I got gold with ifs and switch to GA

Astrobytes: Time to learn a framework and get a job as a code monkey

MSmits: maybe struct codes really long lines

Wontonimo: and golfs them

struct: let me check

darkhorse64: with UTF16

Astrobytes: 2000 line bot in 100 lines of japanese chars

Astrobytes: *symbols

MSmits: mmmh how would that work

MSmits: dont they only go in strings?

struct: ok its 120 lines

Astrobytes: don't be so literal

Astrobytes: :P

struct: with 6? ifs?

MSmits: yes literals

MSmits: thats what i meant

MSmits: :P

Wontonimo: :)

MSmits: struct, why do you need 120 lines for 6 ifs

MSmits: 100 lines of comment?

struct: reading inputs

Wontonimo: he didn't want loops

MSmits: ah

struct: also I calculate distance

struct: and some other stuff

Astrobytes: Legend with that? Nice. I know it's doable without sim + search but that's impressive.

MSmits: velocity

struct: no

struct: I just check if ball is alligned to goal

MSmits: ah ok

struct: So I can use flipendo

PatrickMcGinnisII: just read the loca, post mortem, some of the NN strategies are very interesting

PatrickMcGinnisII: loca=locam

MSmits: is a nn nr 1?

Astrobytes: darkhorse64: nice clobber bot, what's your approach? ab or mcts?

MSmits: wait huh

darkhorse64: you like my boss ?

Wontonimo: oh PatrickMcGinnisII you suggested Ghost in the cell. thanks. Noone liked anything from my list. That's very interesting

MSmits: gitc is fun

MSmits: not easy to write a seach for though

MSmits: search

darkhorse64: Just kidding, mcts

Astrobytes: darkhorse64: the boss is some random crap

Astrobytes: Nice.

Default avatar.png Jstn123: I need some help coding. Is there anyone who can teach me

**Astrobytes flees

MSmits: I remembered I need to go do that thing in the thing with the thingy

reCurse: Sorry cat is on fire brb

struct: o.o

AntiSquid: ^ don't overcook it

MSmits: don't smoke near the cat

Astrobytes: *don't let the cat smoke

MSmits: and that

jacek: who let the cats out?

PatrickMcGinnisII: the cat smokes AFTER you put her fire out

MSmits: :scream_cat:

Astrobytes: who let the cats out? meow, meow-meow-meow...

Wontonimo: Jstn123 the challenges here mostly assume you have the basics down, like if statements and loops.

AntiSquid: Jstn123 the secrets of the universe can be unlocked by googling this passphrase: lmgtfy

Default avatar.png Jstn123: what

Default avatar.png Jstn123: thank you?

Wontonimo: https://letmegooglethat.com/?q=learn+basic+programming

AntiSquid: thank the galactic spirit

Default avatar.png Jstn123: who

Astrobytes: oh that's where lmgtfy went

tibithegreat: I clicked on the link because I waned to see what the animation looks like

Default avatar.png Jstn123: oooh ok

tibithegreat: and google now probably thinks I want to learn basic programming

tibithegreat: I'm probably gonna get some weird ads the next few days

Default avatar.png Jstn123: yep

MSmits: google thinks I want to learn to work the stockmarket and buy/sell houses

Astrobytes: Nothing wrong with throwing them off the scent ;)

MSmits: i have 0 interest in that

MSmits: but keep getting the adds, for months now

darkhorse64: adblock saves your time and your bandwidth

Default avatar.png Jstn123: who codes using lua

Astrobytes: Absolutely no one.

AntiSquid: i think it was from the Foundation Trilogy, not sure anymore, but you should definitely read it Jstn123

reCurse: ublock origin

reCurse: adblock and ublock are riddled with bad stuff

Default avatar.png Jstn123: what about java, anyone use that

MSmits: what bad stuff?

PatrickMcGinnisII: Wontonimo some basic algorithms to have in your arsenal are mostly pathfinding, like dfs, dijkstra ... but alot of times with these contests bruteforcing, mcts, alphabeta min max, etc. is all about maximizing nodes... ok ill shutup, i never get large number of nodes

Wontonimo: tibithegreat nice jump in rank on uttt

struct: 3 billion devices

AntiSquid: lua is used for cheatengine scripts Astrobytes !

reCurse: lmgtfy ;)

struct: iirc adblock sells data if you dont opt out

MSmits: do quality nodes instead of quantity PatrickMcGinnisII

Astrobytes: AntiSquid: it has it's uses, that and Roblox I suppose. You were correct about Foundation btw

tibithegreat: Wontonimo the only change I made was that I was running iteration until 95 ms passed from the turn time

MSmits: have the bestest nodes

tibithegreat: and I changed it to 99

AntiSquid: well ublock origin is from the actual creator

Wontonimo: @PatrickMcGinnisII thanks. Yeah thats good stuff !

Default avatar.png Jstn123: everyone here is nice, I like that

PatrickMcGinnisII: I had to google lmgtfy

reCurse: rip

Astrobytes: 'ded'

MSmits: :door:

Wontonimo: tibithegreat i've got mine set to 98ms and it is just enough to not time out. HAve you tried pushing it closer and watched the replays to make sure you arn't getting dropped?

Default avatar.png Jstn123: can some one go on marslander with me

MSmits: that one looks like tombstone/crypt door to me

Wontonimo: tibithegreat oh, sorry, didn't read your update

Astrobytes: Jstn123: I'm low on gas and you don't have a spacesuit

Default avatar.png Jstn123: lol

tibithegreat: Wontonimo I just pushed it to 99, did a few matches against a default AI

AntiSquid: Astrobytes ah yes it is, that book is awesome i wish they'd made it into a movie, TV series without butchering it, but that's too much to ask

tibithegreat: saw it was good

Astrobytes: AntiSquid: Weren't they doing it?

Westicles: All that psychohistory business was a little sketchy

Default avatar.png Jstn123: byeguys be back in maybe 10

MSmits: see ya in 10 days

AntiSquid: idk, got to check

Astrobytes: Was of its time I suppose

PatrickMcGinnisII: So SOMEONE made me download IntelliJ... is anyone currently using google adMob? I mean, does it really make any $?

AntiSquid: are you sure Westicles ? it's very well explained + you should check out stuff like this https://massivesci.com/articles/brain-brain-interfaces-mind-control/

MSmits: is this a maffia thing PatrickMcGinnisII?

PatrickMcGinnisII: adserver for mobile apps/games

MSmits: join google adMob.... or sleep with the fishes

Westicles: I always wondered if Popper wrote The Poverty of Historicism after reading Foundation

AntiSquid: some no longer secret US research was dealing with reprogramming people with just light signals ... crazy

MSmits: works fine

MSmits: i see students all the time getting reprogrammed with that rectangle that gives off light they're always looking at

Wontonimo: that concept of reprogramming with light really got into mainstream movies

Astrobytes: Intriguing theory westicles

Astrobytes: *idea

Astrobytes: Yeah MSmits

PatrickMcGinnisII: AntiSquid MKUltra lol. LMDR is shown to be innefective w/o the use of drugs

Wontonimo: Foundation series was fun. inspiration to a few nice space rpgs

MSmits: I've been rewatching the series 24

MSmits: they use a lot of drugs in interrogations

Astrobytes: Wat

AntiSquid: easy fix imo PatrickMcGinnisII

PatrickMcGinnisII: ahh another Asimov fan

Astrobytes: We've been directly and indirectly talking about Asimov (spec. Foundation) for the last 5 minutes PatrickMcGinnisII

Default avatar.png UnnamedCodinGamer: first three books of the Foundation series were good

Default avatar.png UnnamedCodinGamer: then it got a bit watered down

PatrickMcGinnisII: I need a nuclear powered throne

Default avatar.png UnnamedCodinGamer: but great imagination

AntiSquid: it got a bit weird :D

Astrobytes: Oh hey UnnamedCodinGamer: did you start your MCTS tutorial tech.io thing?

Default avatar.png UnnamedCodinGamer: no, not yet

Wontonimo: what's that?

AntiSquid: i thought biological internet of things at galactic scale is cool

elderlybeginner: when and how do you eject in codebusters?

struct: you dont know tech io Wontonimo?

Astrobytes: It was a bit of a mindf**k after the first 3 it's true

Default avatar.png UnnamedCodinGamer: but I shared the link in the chat

Wontonimo: struct nope, but now i do

struct: i guess cg is doing something wrong then

Wontonimo: UnnamedCodinGamer are you making a MCTS tutorial there?

struct: or did they just abandon it?

Astrobytes: I missed that link, must've closed the window after I was afk earlier

Default avatar.png JayM9: h

Default avatar.png JayM9: hi

PatrickMcGinnisII: someone mentioned a VB run powergrid yesterday... but that's how they do things in Texas. ;)

Wontonimo: OH ... yeah, i recognize it from the playground thingie. didn't really pay attention to the branding tbh

Astrobytes: struct: They've never really used it to it's potential imo

Astrobytes: PatrickMcGinnisII: :rofl:

struct: Well its like me

Default avatar.png UnnamedCodinGamer: I had an idea to make a playground - simple code to play around with - more of a proof of concept thing

struct: I write the sim then never finish the actual AI

struct: So its wasted potential

Astrobytes: But you make great games nonetheless

Astrobytes: And you still have time to fulfil that potential

struct: I dont really like to think I make games

struct: I only port them

Astrobytes: CG have kinda missed their own boat wrt tech.io

Astrobytes: Yeah OK, but good ports

AntiSquid: just need to think of it as a game that plays itself or a game that plays other games and then maybe you can finish it struct

Default avatar.png UnnamedCodinGamer: Astrobytes, here is the link https://tech.io/snippet/2oI54uz

Default avatar.png UnnamedCodinGamer: I do not know if it is understandable enough

Wontonimo: my kids laugh at me for programming my computer to play games for me ... sigh, I haven't converted them yet

Default avatar.png UnnamedCodinGamer: consuming is easier than creating

AntiSquid: show them the power of automation in their own games

jacek: power of AutomatonNN

AutomatonNN: who the first test case doesn't work for me

Wontonimo: Noooooo

tibithegreat: show them factorio

tibithegreat: that should get them to learn the power of automation

AntiSquid: what are they playing Wontonimo

Astrobytes: UnnamedCodinGamer: after I had my adrenaline shot for unexpected exposure to Java (j/k) I have seen your code. Decent basic implementation, speaks for itself if you know it but if you want it to be useful you might have to break it down into chunks with more explanation?

Wontonimo: my son was pretty big into redstone mechanics, so partly redeemed

Wontonimo: AntiSquid currently, my son is into some FPS and my daughter still into minecraft

Default avatar.png UnnamedCodinGamer: Astrobytes, hah

Default avatar.png UnnamedCodinGamer: it is based on code that I wrote a while back

Default avatar.png JammSpread: you should try getting them into minecraft modding

Default avatar.png JammSpread: serverside plugins is easier

AntiSquid: FPS -> autoaim scripts, minecraft -> MineRL challenge, damn even making a diamond is hard

Astrobytes: UnnamedCodinGamer: the code doesn't have to be optimised or anything, just explanations alongside the snippets of each part, then full code at the end to play with

Wontonimo: i made a server side mod for them a few years back, gave everyone classes and power phrases... they loved it, but again just interested in consuming not creating

struct: garrys mod also allows you to code inside the game

struct: you can use lua

Default avatar.png UnnamedCodinGamer: I am not sure about more explanation - as I imagine it it should be for people who have read the theory but for some reason struggle to implement it

struct: or expression 2

Default avatar.png UnnamedCodinGamer: as I did

Wontonimo: struct garrys mod eh? oh, that's cool

KelvinAndHobbes: Gotten the "Capcta: are you a human" 3 times in a row in CoC, does it just really think I'm a bot?

Astrobytes: UnnamedCodinGamer: Is there not full Java code out there already?

Default avatar.png JammSpread: stackoverflow does that every time i search now

geppoz: uhm the "mars lander" banner was always that way or they updated in honor to Perseverance?

Default avatar.png JayM9: I am getting major errors

Default avatar.png JayM9: I am unsure why

Astrobytes: Talk to General Problems, he will help JayM9

Wontonimo: geppoz afair it's been that way always

geppoz: so that landing configuration was known years ago? nice

Westicles: geppoz, what's up with all that math in your beach volleyball solution?

Default avatar.png UnnamedCodinGamer: Astrobytes, maybe, but I am bad at reading other people's code

tibithegreat: geppoz the skycrane was used for curiosity as well

Default avatar.png UnnamedCodinGamer: for some reason I think that my version is clearer :)

Astrobytes: UnnamedCodinGamer: That's fair, it takes some practice that's for sure

geppoz: Westicles that the solution of a 4th grade equation

Default avatar.png UnnamedCodinGamer: which may not be true

Astrobytes: UnnamedCodinGamer: I find it clear yeah

geppoz: tibithegreat uh, I didn't know, ty, I tought was still airbag tecnique

Default avatar.png UnnamedCodinGamer: thanks for looking at it

geppoz: Westicles that is a O(1) solution of the problem ;)

Astrobytes: No worries, maybe other people can contribute to it with other language implementations?

Astrobytes: @UnnamedCodinGamer

Westicles: I see. I tried to take the derivative and find a closed-form solution, but couldn't get it

Default avatar.png UnnamedCodinGamer: yes

Wontonimo: I had added the label "Snell's Law" to the challenge but for some reason it got removed.

Westicles: They only allow approved tags

Wontonimo: "Snell" is just so racy ... i get it

Astrobytes: lmao

Default avatar.png UnnamedCodinGamer: or other implementation of certain steps - for instance here at the expansion step all children are expanded at once - you can expand single child at a time

geppoz: Westicles https://ibb.co/KjSGYBt

Default avatar.png UnnamedCodinGamer: it saves memory

Astrobytes: Sure, depends on your node size but yeah, different implementations would be cool

Default avatar.png UnnamedCodinGamer: I have it already

Default avatar.png UnnamedCodinGamer: in another version

Westicles: nice

Default avatar.png UnnamedCodinGamer: less nodes are being created

Wontonimo: what i found useful for my first implementation of MCTS (which you may want to include) is a deterministic example to turn into a unit test. An example is here https://www.youtube.com/watch?v=UXW2yZndl7U

geppoz: it would be great if CG would rate solutions based on time/memory consumption

Wontonimo: don't know if unit tests are all the rage where you are publishing this

geppoz: it will become little more interesting to optimize even the normal puzzles

AntiSquid: seen, best video on mcts Wontonimo :D

Astrobytes: geppoz: I guess that's only really doable with the bot programming

Default avatar.png UnnamedCodinGamer: I will take a look

Wontonimo: AntiSquid and that's saying sometrhing considering the crazy shaking of the camera

AntiSquid: in general very few youtubers get straight to the point and explain things clearly

geppoz: Astrobytes, no, leetcode does it

Wontonimo: geppoz, no, leetcode + that guy = still very few

Astrobytes: geppoz: Sure, and projecteuler too iirc, I just mean with the way CG is currently set up

Wontonimo: lol

AntiSquid: leetcode also rates you based on fail attempts no?

AntiSquid: find that a big drawback

Astrobytes: That's the 1337 part :P

AntiSquid: pointless stat

Astrobytes: ...?

Astrobytes: It would just be code without the leet!

Wontonimo: sorry geppoz .. i got confused

Astrobytes: I do agree though AntiSquid

Default avatar.png UnnamedCodinGamer: Wontonimo, I remembered watching this video a couple of years back

Default avatar.png UnnamedCodinGamer: it is a nice one

Default avatar.png UnnamedCodinGamer: however if I remember correctly it is an implementation of single player mcts

Default avatar.png UnnamedCodinGamer: (explanation)

Default avatar.png dericeketli: alooooooooooooo

Astrobytes: +extra points for the lecture being for the University of Strathclyde (Glasgow, Scotland)

Default avatar.png UnnamedCodinGamer: I love the way he goes into details

Default avatar.png UnnamedCodinGamer: showing exactly what is happening

Astrobytes: Yeah, good lecturer

Wontonimo: WW bot game never came up in the top recommendations, yet I seem to recall there being some positive chat about it. Thoughts?

Astrobytes: Yeah, good game

Astrobytes: I need to get back to that actually

Astrobytes: Very fun

Astrobytes: Based on this iirc: https://boardgamegeek.com/boardgame/194655/santorini

AntiSquid: it depends from person to person Wontonimo

Astrobytes: Ofc, as I said earlier it's all very subjective. You should try everything

AntiSquid: the contests back then also had the disadvantage of a forced break after contest, you lost interest completely by the time it got released

AntiSquid: you can play it online: https://boardgamearena.com/gamepanel?game=santorini

not sure if you need premium account for this one

Wontonimo: pull a codebullet and make a bot slaughter humans

darkhorse64: I have tried almost every multi on CG: there are 3 that are so-so for me: Code Royale, Code of Kutulu and mostly Botters of The Galaxy. All others are interesting to play

Wontonimo: oh, code royal is iffy, good to know.

Wontonimo: i was looking at Botters, and it just seems too kludgy for me.

Wontonimo: I get it, the makers were trying to probably do something anti-mcts

Wontonimo: and it was fun to write some if/then/else for it, but ultimately not really my speed

darkhorse64: Too messy for me. My favorites are OOC, PCR, Crystal Rush, Yavalath

Astrobytes: BotG is a no-go for me, didn't like PacMan, Code Royale was so-so, That Cooking Game (Code a la mode),

struct: o.o

Wontonimo: who made BotG?

Astrobytes: I'm a cussy funt though

AntiSquid: there was no intent to make it anti-mcts lol

Astrobytes: Hmm Wontonimo, ask AntiSquid :D

Wontonimo: AntiSquid who made BotG?

AntiSquid: after some debate, we decided to make it focused around optimizing last hit deny on lane-units

darkhorse64: I like Code a la Mode & Code of Ice and Fire too. For most of the multi, there is something to learn

AntiSquid: it says in the description Wontonimo

Astrobytes: Oh COIF was great

AntiSquid: and it has a story !!

struct: my problem is I dont really know how to code for some of those games

struct: like CoIF

Astrobytes: I hacked my way through it

Wontonimo: well, i must be blind cuz i can't find it

AntiSquid: the more i play coif the more i wonder why complain about some of the other games but praise coif

struct: https://www.codingame.com/multiplayer/bot-programming/a-code-of-ice-and-fire

Wontonimo: i'll keep looking though

Astrobytes: Hacky solutions the whole way through

AntiSquid: CIF *

AntiSquid: me and some others, one sec pls Wontonimo

AntiSquid: https://www.codingame.com/multiplayer/bot-programming/botters-of-the-galaxy here at the top it says

AntiSquid: there wasn't even the intent to make it "hard to simulate" lol

darkhorse64: Once again, nothing personal against these multis and congrats to the people who made the effort to design it

AntiSquid: i am not taking it personal, you dislike it fine w/e

Astrobytes: (but we still hate them :stuck_out_tongue_winking_eye: )

AntiSquid: i hate some multis and i wonder why do they get praise, could use same arguments against them

Astrobytes: I will make an effort in BotG one day, but it's after UTTT for me (that means real low)

Default avatar.png JayM9: damn boys

Default avatar.png JayM9: just took an L

Astrobytes: Ofc, everything is subjective

Default avatar.png JayM9: in the clash of code

Default avatar.png JayM9: could not figure it out

Default avatar.png JayM9: RIP

Default avatar.png JayM9: is there a way to look at past clash of codes

Default avatar.png JayM9: so I can go back and do the

Default avatar.png JayM9: withou the time

Wontonimo: hey, i'm in wood 1 in BotG lol

Astrobytes: if you remember some keywords or the name sure JayM9

Astrobytes: https://eulerschezahl.herokuapp.com/codingame/puzzles/

darkhorse64: Hate is a very strong word, let's just say that some multis motivate me more

Astrobytes: *strongly dislike

Astrobytes: *find unappealing

darkhorse64: Yeah, ths one

darkhorse64: *this*

Astrobytes: 'hate' can be used without much impact in English depending on tone and context, in French I think it's not quite the same

Astrobytes: also, tone and context on the internet :rolling_eyes:

derjack: :skull:

darkhorse64: It's almost like saying you want to murder someone

AntiSquid: hey just imagine how the guys at openAi felt while working on their dota2 project then, they stopped at 17 heroes i think and they ended up with a simplistic push one lane tactic for most part

Astrobytes: darkhorse64: Yes, that's very much the case in English if you use it aggressively. It's a commonly abused word that has lost its traditional impact over time.

derjack: bloody hell

Astrobytes: derjack is becoming unionjack

JohnathanBarbee: I don't know. I very much want to murder my code some times.

Astrobytes: That's a private grievance :P

JohnathanBarbee: :grinning:

Default avatar.png JammSpread: why do i feel that shortest code problems on clash of code makes python op

Astrobytes: Because you don't know Ruby

Default avatar.png JammSpread: oh lol

Default avatar.png JammSpread: i forgot them both

Astrobytes: Right tool for the right job

Default avatar.png JammSpread: lol

Default avatar.png JammSpread: i use javascript in the meantime

Astrobytes: You can still get decent results, you just need to practice golfing it

Default avatar.png JammSpread: I just wish you could multiply strings like you could in py

Astrobytes: what is it in js? repeat()?

Default avatar.png JammSpread: yeah I think String.repeat

Default avatar.png JammSpread: still pythons operations i find superior

Astrobytes: Like I said, if you wanna win golfing you need the right tool for the job

Default avatar.png JammSpread: Ok then, I'm going to retry learning python. Thanks.

Astrobytes: I don't do it myself but it's the way to go. Ruby is also ridiculously OP in regards to golfing

Astrobytes: If you do it right.

Default avatar.png JammSpread: yeah its the langs that try not to be too verbose and easier to learn

Default avatar.png JammSpread: don't even try golfing in Java

Astrobytes: There's attempting to compete and there's just pain. Choose attempting to compete :P

Default avatar.png JammSpread: Totally, I tried one of them recently and even making a util function for the job was a headache.

Theino: I do most coding in C#... I'm always very sad when I get a code golf problem

Default avatar.png JammSpread: C#, Java and C++ require boilerplate to even do a hello world.

Astrobytes: If you're not bothered about ranking in clashes then that's fine. Clash ranking depreciates anyway

Astrobytes: You can do puzzles/multis/optims instead for more permanent ranking

Default avatar.png JammSpread: I mean when they show you a metric even if you don't try to care its hard not to.

Astrobytes: (and code golf too, though it's only 4 or 5 puzzles)

Theino: I just try to hack it together in python and not come in last

Theino: I started learning ruby before I decided I didn't want to work that hard for a few code golf problems

Theino: I might change my mind...

Astrobytes: Yeah, it takes some work to learn how to make things *that* unreadably short lol

Astrobytes: But hey, I don't clash.

Theino: I haven't been on codingame in awhile and found the new quest map... it made me want to do clash again

Astrobytes: Hehe, you and a bunch of others :D

Astrobytes: I gave that particular branch a miss

Default avatar.png JammSpread: The several character long langs on code.golf seem to be an utter headache

Wontonimo: that quest map ... it dug deep into some primal motivation for me

Astrobytes: Worked as intended then I guess.

Astrobytes: It's cool you're digging the multis and not just clashes or whatever

Astrobytes: It makes me somewhat sad when I see people missing the real meat of the site.

**BlaiseEbuth cough cough 5% cough cough.

Astrobytes: Yeah. Innit.

Astrobytes: Also BlaiseEbuth thanks for returning to normal form :D

Default avatar.png **JammSpread is joining a new clash

BlaiseEbuth: Yeah. I prefer this one too.

Astrobytes: :)

Astrobytes: gn all

MSmits: gn!

Default avatar.png JammSpread: gn

Wontonimo: gn

jacek:

Wontonimo: i'ma gonna go

Wontonimo: 2

Default avatar.png JammSpread: bye

AntiSquid: gn8 astro

Default avatar.png Guillermo.: gn

milad-mehri: ~~test~~

milad-mehri: lol

Default avatar.png JayM9: yo

Default avatar.png JayM9: can someone help me

Default avatar.png JayM9: i am doing coders strike back 2

Wontonimo: hey, how can i help?
