Kellthazar: I finished my simulation + genetic algorithm a couple of weeks ago, but I couldn't thought a clever way to create a initial population. I tried several ways til think on "force" the initial genes with a pre-established directions... Then the magic happened! :D

Passifi: So pythons range function doesn't support floats just as I am warming up to that language it backstabes me ... everytime ...

AgathokakologicalBit: Does anyone have code for simulating MarsLander game?

derjack: Passifi use numpy arrange(?)

DaNinja: Muzkaw has a video on building a Lunar Lander app https://www.youtube.com/watch?v=bcYXlosxBzk

Passifi: yo derJack yeah i found that one too. but thanks :)

AgathokakologicalBit: @DaNinja, thx

MeSeet: NN+GA (NEAT) in js vs in python? What are your thougths?

KiwiTae: C++ ftw

derjack: youll get more tools for python. for performance, of course c++

derjack: though python acts here as wrapper for c++ stuff

MadKnight: MeSeet what exactly kind of combination ?

Joseph_Mother: Ay ay ay

Joseph_Mother: cmon now

Joseph_Mother: :flag_il:

Joseph_Mother: Dang 38 seconds

Joseph_Mother: im not bad huh

Joseph_Mother: I got an issue yall

Joseph_Mother: When u print numbers in lua its like 1.0 instead of 1

Joseph_Mother: and it causes alot of issues n stuff and ive lost clashes before because of it

Joseph_Mother: so i have to do like tostring(num):sub(1,-3) every time i need to output a number

DaNinja: did you try ~~x or x|0

Joseph_Mother: that aint valid lua syntax

DaNinja: x-x%1

Joseph_Mother: lol

Katespizer: is cursing on CoC channels allowed?

jacek: bloody hell!

AgathokakologicalBit: Oh, my stars and garters! O:

Q12: Can somebody that know python very well help me in "Don't Panic" optimization challenge? Need to be less than 200 characters but the closest I get is 296. I think that my current way of solving is enough to complete it, just need to reduce the number of characters and don't know how.

RoboStac: if you've solved it you can check other peoples solutions in the standard (non golf version). See if there are any ideas in there you can use

JerWhatIsCode: ^ this is super useful looking at others code even if you solve any puzzle perfectly fine. I think it's the best part of this site, being able to see how other people approach the same problem.

Default avatar.png NicknameAlreadyTakenHelp: bad

Q12: Thanks a lot, good idea @RoboStac and @JerWhatIsCode :thumbsup:

KelvinAndHubbles: how long till the "Max number of submissions and test cases tried" thingy goes away?

MadKnight: hmm where did u get that ?

KelvinAndHubbles: Code Vs Zombies

KelvinAndHubbles: its due to a lot of test cases

MadKnight: do u test them all at once very often ?

KelvinAndHubbles: well yeah, thats why I have the notif, probably should just be doing some lower down ones

MadKnight: there's one pretty important

MadKnight: that can give u 464k for just that 1 test

MadKnight: https://www.codingame.com/replay/310155287

MadKnight: use this one instead of them all

Uljahn: KelvinAndHubbles: you are given 25 submission attempts per 5 hours, it doesn't depend on the number of validators i guess

Default avatar.png Rakotoo: Pour vous les boys

MadKnight: the solution is already in Hints

Default avatar.png Rakotoo: On sait jamais

AntiSquid: who is Jamal ?

Default avatar.png deoignition: asm >>> python

BlaiseEbuth: Don't know this operator... :thinking:

Default avatar.png deoignition: Is that a reference to :joy: the popular game :rage: amogus :joy: :joy: :laughing: who is sus!?!? :rage: who :flushed: is :smirk: sus :sob: WHOWO :pensive: amogus is best game :joy: bcuz is was coded in asm :innocent: best languiui :hugging:\

Astrobytes: Are you unwell in some way?

Default avatar.png deoignition: yes :weary:

Scarfield: wait, i thought both uljah-n and blaise were mods?

Astrobytes: Desist with spamming crap please.

Default avatar.png deoignition: ok bby :kissing_heart:

BlaiseEbuth: Scarfield : The server has eat our badges ! :scream:

Astrobytes: Scarfield, they were but there was an issue the other day that wiped some of the mod rights

Scarfield: :screa:

Scarfield: :scream:

Astrobytes: ScreamField

Scarfield: ScaryMovieBytes

jrke: even i just noticed that some mods removed, But why

BlaiseEbuth: certificats update.

BlaiseEbuth: You don't see the link ? Me neither :D

jrke: link?for what

BlaiseEbuth: The link between certificats update and the moderator rights.

jrke: https://www.codingame.com/playgrounds/40701/contribute---help/chat-moderation

jrke: ^^ i can see the name of ebuth here

Scarfield: Astrobytes https://prnt.sc/10ncweh

eulerscheZahl: https://static.codingame.com/servlet/fileservlet?id=23052489191875

AntiSquid: i never see some of those people around jrke

MSmits: it should go here eulerscheZahl: https://isthisacat.com/

eulerscheZahl: https://imgur.com/a/FV9dScT

MSmits: haha

Scarfield: wonder what it is then

MSmits: what kind of demon is it then?

eulerscheZahl: an impurrstor

Scarfield: xD

MSmits: :grin:

Scarfield: ty for the link euler, but high res requires more than low effort :p

MasterCoderxD: hey

Scarfield: hi

MasterCoderxD: what does (t := b) mean?

eulerscheZahl: it also shows some background

MSmits: set t equal to b

eulerscheZahl: Pascal syntax

MSmits: or bind t to b

AntiSquid: is it new python syntax?

MSmits: or syntax error, depending on the language

MasterCoderxD: like? t=b?

MasterCoderxD: it's just basic algorithm yntax

MSmits: yeah t = b should be similar

AntiSquid: like tell us what language you're using lol

eulerscheZahl: pseudo code

AntiSquid: or you could look it up in language docs yourself

MasterCoderxD: it was a pseudo code bro

MSmits: oh, current puzzle of the week was created by happy-jacek

AntiSquid: https://softwareengineering.stackexchange.com/questions/101716/in-pseudo-code-what-does-mean


MasterCoderxD: thanks bruv

AntiSquid: forgot this goes along with it MasterCoderxD https://lmgtfy.app/#gsc.tab=0

jacek: happy-jacek?

eulerscheZahl: https://www.codingame.com/profile/1b727538d147d9eb687b82915f3539e28521681

jacek: pretty avatar

MSmits: yeah it's like jacek only even happier

jrke: thats why its 'happy-jacek'

MSmits: you got it

eulerscheZahl: i sneaked in a link to the wrong profile and you didn't complain :(

MSmits: that's dark jacek

MSmits: don't confuse the two

eulerscheZahl: or "snuck" :thinking:

MSmits: or "snookered"

jacek: no one noticed i mirrored my avatar few weeks ago :(

eulerscheZahl: no, snuck https://www.youtube.com/watch?v=PJVNzwTnfbk

jrke: just noticed after your message

BlaiseEbuth: I noticed.

MSmits: this teaches me things about your google preferences euler

jrke: i noticed before you changed your mirror avatar ;)

MSmits: It shows me alot of conan too :)

eulerscheZahl: there's a spider! right above my chair

eulerscheZahl: god dammit

eulerscheZahl: it was a little beside 5min ago but it moved

jrke: so, toad v/s spider

BlaiseEbuth: tongue

Default avatar.png Rakotoo: Claquette chaussette

ZarthaxX: who won?

Default avatar.png Rakotoo: me

ZarthaxX: toad the spider got you? :P

ZarthaxX: toads eat spiders

eulerscheZahl: FJAFJKLDSKF7JKFDJ

Scarfield: im still worried, might be a david goliath scenario

BlaiseEbuth: The spider walks on his keyboard :scream:

eulerscheZahl: did you recognize the reference?

jrke: the one more hungrier should have won

jrke: gtg b-bye

eulerscheZahl: it's walking

eulerscheZahl: ok i'm done, time to get it outside

ZarthaxX: what was that :rofl:

Scarfield: no idea about the reference, and was too slow to link the conan video first :'(

ZarthaxX: ah walking onthe keyboard lmao

eulerscheZahl: https://xkcd.com/1530/

Default avatar.png Got_Games: hi

eulerscheZahl: you all would have failed to rescue me, i'm disappointed

ZarthaxX: LOOOOOOL

ZarthaxX: that meme fits so well

ZarthaxX: did you type the exact string? lol

eulerscheZahl: of course

Scarfield: xD

Default avatar.png deoignition: remove shortest code mode right now :rage:

KelvinAndHubbles: make reverse + shortest mode now >:D

jacek: it would be easier actually. once you figure out reverse, you have more time to complete it

eulerscheZahl: make a new mode: you get a solution and have to find a puzzle

Default avatar.png deoignition: reverse mode is oke

Default avatar.png deoignition: shortest code mode is garbage cuz python always wins

jacek: use ruby [solved]

KelvinAndHubbles: or just learn python

Default avatar.png deoignition: :nauseated_face:

Default avatar.png deoignition: i know python

jacek: an how come euler has mod badge when others dont

Default avatar.png deoignition: i just dont want to have to use it

Default avatar.png deoignition: and its unfair to people who dont want to learn a garbage language

struct: a bug caused it jacek

struct: They forgot some people :(

Default avatar.png deoignition: well clearly you are a mod

Default avatar.png deoignition: so you can remove shortest mode from right now :grinning:

darkhorse64: mod not god

Default avatar.png deoignition: :frowning2:

struct: Also you cant please everyone

AntiSquid: deoignition what language do you use?

struct: Plenty of people enjoy shortest

Default avatar.png deoignition: mainly c++

AntiSquid: so just play multiplayer then, c++ usually wins

NoctalIvan: I like shortest. But CoC multi language shortest is so unfair tbh

struct: hmm

struct: Languages have more advantage on shortest than on multies tbh

Default avatar.png ErrorRazor: It's not unfair, you're allowed to pick any language you want

NoctalIvan: Well I'm learning Perl just for this

AntiSquid: python and ruby are for premium VIP members only /s

ANONYMOUS42: ruby or bust

NoctalIvan: I just don't wanna

struct: When I played CoC, I switched between Bash Ruby Perl Js and python

struct: and I dont know any of them well

AntiSquid: so coc didn't help you improve? shocker

NoctalIvan: Yeah same. Mostly python & JS so far

struct: It teached me random math formulas and regex

Default avatar.png ErrorRazor: Didn't teach you the past tense of "teach" though

AntiSquid: i feel like a lot of the ordinary puzzles force you to learn random math stuff

AntiSquid: twat, there's your past tense

Scarfield: ^

NoctalIvan: Actually shortest teaches me a lotta stuff, imo

jacek: happy code review for your coworkers

ANONYMOUS42: how much CoC do you need to play to start getting repeating puzzles

NoctalIvan: About how twisted for loops really work for instance

NoctalIvan: Oh that's a good question. Never had any

NoctalIvan: But some opponents at some points were like waaaay to fast to be reading the problem entirely

ANONYMOUS42: yeah i remember playing it a few years ago and it there were like 20 second responses

ANONYMOUS42: i think it's a bit better now

ANONYMOUS42: or maybe they were just really fast idk

NoctalIvan: Yup, I remember a guy making a bot to auto copy paste the answers to the stuff he had completed once :grin:

NoctalIvan: In uni, years ago

NoctalIvan: Nah. 50 secs can be legit but 20 is too short. Even if they didn't bot anything it's only possible if they knew the subject imo

NoctalIvan: Which technically isn't cheating

struct: If they know the clash under 20 sec is possible

ANONYMOUS42: yes

ANONYMOUS42: that was kind of my point

AntiSquid: not everyone knows the clash and i've seen it too often, even for longer clashes instant submits ...

AntiSquid: so screw clash, unless you want to do shortest for fun

ANONYMOUS42: i always like reverse for some reason

ANONYMOUS42: liked*

Default avatar.png snoyes: I have just completed a clash in 22 seconds, having never seen it before and without using any bot or script or anything else resembling cheating.

jacek: oO

JohnnyHotBody: Dang your good!

Default avatar.png ErrorRazor: What's the max execution time for puzzles? Is it the same for every puzzle? There's nothing specified in potw

jacek: not enough to brute force it in any way

Default avatar.png ErrorRazor: Why would you want to brute force it anyway

jacek: because im dumb

Default avatar.png aamirhs: 15 mins i guess?

Default avatar.png snoyes: where do you manage who you are "following" and who is following you, and what do you see when you follow someone?

AntiSquid: profile page

Default avatar.png Wilster: -=W=-

Default avatar.png jonzel: is it a smart career move in college to do a lot of c++? Or should you rather spend more time with python and java

struct: What do you mean by move in college to do a lot of c++?

Default avatar.png jonzel: like doing private projects where I could chose any language in cpp

Default avatar.png jonzel: oh, I meant "career move" :-D

Default avatar.png snoyes: Is it a (wise thing to do) (while in college) to...

Default avatar.png Wayne_Ker: Hi can someone help me

struct: ah you mean doing side project while in uni?

Default avatar.png jonzel: yeah, sorry english is not my first language

Default avatar.png Wayne_Ker: im building a calculator and im running out of ideas for different buttons

Default avatar.png Wayne_Ker: i already got 40 different and i need 3 more

Theino: do you have addition?

struct: factorial?

Default avatar.png Wayne_Ker: yep

Theino: welp, I'm out of ideas

Grizzly21: PV and FV

Default avatar.png Wayne_Ker: sin cos tan ctn + - * / ** sqrt ...

Default avatar.png Wayne_Ker: !

Default avatar.png Wayne_Ker: | |

Theino: arc sin, arc cos...

struct: mod?

Default avatar.png Wayne_Ker: i dont eve3n know what that is

Default avatar.png Wayne_Ker: ?

Default avatar.png jonzel: rounding

Grizzly21: lots of financial fucntions you can add

Default avatar.png Wayne_Ker: i got pi e log too

struct: modulo is the remainder

Default avatar.png Wayne_Ker: i got rounding too

Default avatar.png Wayne_Ker: i got parantheses

Default avatar.png jonzel: minutes to hours

Default avatar.png Wayne_Ker: that aint that hard

Theino: oh ya, you could fill it up with conversions. lb to kg, minutes to hours, etc, etc

Default avatar.png Wayne_Ker: but i might add it too

Theino: if you want harder, add some calculus functions

Default avatar.png Wayne_Ker: im too dumb for that

Theino: then do conversions :P

Default avatar.png Wayne_Ker: its at least a year till we learn it

Default avatar.png jonzel: riemann zeta function

Default avatar.png Wayne_Ker: k thx guys

Default avatar.png Wayne_Ker: <3

Theino: easy, but useful would be a pi and e button

Default avatar.png Wayne_Ker: got it

Default avatar.png Wayne_Ker: also what i dont understand is why the gui takes few sec to load

Default avatar.png Wayne_Ker: i use tkinter

Default avatar.png Wayne_Ker: py

Theino: I've used tcl/tk but never tkinter so I don't think I can help you there

Default avatar.png Wayne_Ker: i used the time module to count the loading time

Default avatar.png Wayne_Ker: it took 0.2 sec to run from start to end

Default avatar.png Wayne_Ker: bet the gui takes a lot longer

Default avatar.png Wayne_Ker: im in a VM but my pc is good

Default avatar.png Wayne_Ker: so i dont think it is the problem

eulerscheZahl: https://www.codingame.com/ide/demo/8758470df0f4ccc4ad5c774d20935cf59c7698 hm, somehow the dice rotation doesn't match my internal state :/

wlesavo: oh, nice game, i now want to play it like a board game

eulerscheZahl: it is a board game ;)

eulerscheZahl: a buggy one atm

wlesavo: i mean ive never seen that, but now i had :slight_smile:

wlesavo: i think i have enough dices

eulerscheZahl: oh, you mean you want to play in real life?

wlesavo: yeah

wlesavo: btw euler, i finally found an IT job thx to CG :slight_smile:

kovi: gratz!

eulerscheZahl: oh, awesome!

eulerscheZahl: "IOF RAN" is your profile updated already?

wlesavo: starting from april

wlesavo: not yet

eulerscheZahl: tell me more: what field, tech stack? working hours, ...

wlesavo: smart engines, its a small somewhat scientific company with computer vision and tomogrphy development

eulerscheZahl: so in the medical sector

wlesavo: basically crossplatform C++

wlesavo: not really, they doing high resolution CT for material study

wlesavo: their main product is recognition of different document on mobile devices, CT team is quite small, and im starting from CT

jacek: how would you play those dices in real life overlapping?

wlesavo: jacek you eat the dice if you finished on the same place with greater value

eulerscheZahl: "with greater value" - wlesavo inventing new rules :D

darkhorse64: you always move in straight lines ?

eulerscheZahl: no

eulerscheZahl: but can't cross your own path

eulerscheZahl: play boss vs boss

wlesavo: euler oh, i just deduced it would work like that :smiley:

eulerscheZahl: but when a die has the number N on top, you have to move exactly N cells

wlesavo: hm, from boss vs boss replay it looks like moving up to N cells

wlesavo: https://www.codingame.com/share-replay/534566138

eulerscheZahl: broken

eulerscheZahl: the visuals don't match my internal state

wlesavo: in the end there red cube goes back and force 1 move, even with broken visuals that cant be right

eulerscheZahl: i can't open your replay

eulerscheZahl: it's private

wlesavo: https://www.codingame.com/replay/534566138

eulerscheZahl: Oups An error occurred (#UNAUTHORIZED): "You are not authorised to view replay 534566138".

wlesavo: hm

darkhorse64: you can't share replay in wip

wlesavo: i see

darkhorse64: It's quite bad for bug reporting. CG, please fix it !

eulerscheZahl: i told CG to fix it when I found a BotG replay before the contest started :(

eulerscheZahl: now it's not even relevant anymore as community contests are dead

jacek: revert commit then

eulerscheZahl: and at least I (as the creator) want to see the replays even if the arena is private

wlesavo: http://chat.codingame.com/pastebin/bcd4619c-d05a-403b-a350-dd772a438ec6

darkhorse64: It should be an option. Share if you wish, by default don't share

jacek: make it password locked

eulerscheZahl: options are always good

darkhorse64: same as allow people to dowload the boss code

darkhorse64: Oops, always on

darkhorse64: :grimacing:

eulerscheZahl: well, my internal state of the die is really broken :D

jacek: hm?

darkhorse64: private jke

darkhorse64: *joke*

struct: dark horse I had no idea it was possible when I asked you for othello boss :/

darkhorse64: No worries, I took care to remove some parts of my usual MCTS code

darkhorse64: Lesson learned, I will always write crappy minimax bosses

darkhorse64: That's what I did for Clobber

Default avatar.png Tuo: Is the clobber boss supposed to be easy?

leojean890: darkhorse64 one time, a boss code was public on github ?;)

leojean890: same question as Tuo xD no it's not very easy^^

darkhorse64: No, I made it tough

Default avatar.png Tuo: i keep trying and trying and its not even close

struct: no leojean890 its worse than that

leojean890: it's alpha beta with good eval

leojean890: and god perfs

leojean890: good*

darkhorse64: leojean890: do you refer to the public Clobber repo ?

leojean890: struct how worse ?:P

Astrobytes: eh, ClobberSan is designed to test you

leojean890: darkhorse64 you told me about your boss a few days ago

leojean890: Astrobytes advised you about the eval and you did good perfs^^

darkhorse64: The boss on the repo is a dummy one

leojean890: but not iterative deepening

leojean890: depth depending on branching factor

leojean890: like I did but better than how I did it;)

darkhorse64: Poor's man iterative deepening

Scarfield: Astrobytes i think you missed this ealier https://prnt.sc/10ncweh

Astrobytes: darkhorse64: :D

darkhorse64: Tip: implement a MCTS. Mine has 90+ % winrate against the boss. No eval needed

AntiSquid: hey clobber has no cover art

AntiSquid: fix it

jacek: who approved it :\

Astrobytes: hahahaha Scarfield

Default avatar.png Tuo: my bot can do 15k 15 step full random sims and 18 total moves left min max.

Scarfield: :)

struct: leojean890 I prefer not to discuss it in public anymore

darkhorse64: I am a dev, not an artist

Astrobytes: Can't you do a bigger one? I can't use that as an avatar!

Default avatar.png Tuo: suold this be enought?

AntiSquid: devs know how to upload image files

Astrobytes: struct: wise move

leojean890: struct darkhorse64 one time, a boss code was public on github ?;)

leojean890: struct oh ok

leojean890: not in public, right, sorry;)

AntiSquid: fix breakthrough cover art while you're at it

darkhorse64: Same answer

darkhorse64: Tuo: I did not understand

Astrobytes: Oh yeah, I started breakthrough today, any tips?

AntiSquid: i'll make a tutorial on tech.io how to upload a cover image

jacek: Astrobytes bitboarding?

darkhorse64: No tip from me. I suck at my own game

Astrobytes: jacek: that's a given

AntiSquid: and paper soccer could have cover art as well

jacek: then its relatively cheap to find/avoid 3-ply win-lose, possibly more with more ifs

darkhorse64: devs don't know how to design images

AntiSquid: they know how to click select image and click upload and click confirm

jacek: and home row is quite important

jacek: but what image to select

Astrobytes: mcts or ab approach is best? Or around the same? And yeah.

Astrobytes: Guessing ept works here

Default avatar.png Tuo: darkhorse64 for MCTS you make a move and simulate game for x turns right? More sims the better and then minmax the end

jacek: i used ab approach originally, it is quite evalable

Astrobytes: Yeah, there's a bunch of heuristics to use

darkhorse64: Tuo: interesting approach. I use a solver instead of minimax

Default avatar.png Tuo: i thought the idea of clobber is to get as many sims as possible, hats what iv been doing for days :D

jacek: it is true for mcts generally

darkhorse64: I have 120k full random rollouts second turn

jacek: and you do mcts until the end

Default avatar.png Tuo: So im not even close to beating the bot with 5-10k

darkhorse64: Astrobytes: MCTS/EPT but my eval is crappy

jacek: huh? bot has 120k rollouts?

darkhorse64: :nerd:

Astrobytes: darkhorse64: good to know, thx

jacek: how do you people count the roullouts? i always have 10x less yet im at the same level

struct: 1 rollout = 1 play until end?

darkhorse64: yes

jacek: thats how i count it

jacek: :thinking:

Astrobytes: 'Harnessing' that pony magic jacek

jacek: and i always have the solver implied

Astrobytes: For some games though you do things a little differently from some of us

darkhorse64: Same. My rollouts are dumb

jacek: im talking vanilla mcts. for uttt before i had 10k in second turn, yet people claimed they had over 100k

jacek: and i was top20

Astrobytes: Yeah but didn't you do something different there? (that's specifically the one I was thinking of)

jacek: i had some heuristics biasing the selection and rolloutsbut rather light ones

darkhorse64: Send me your uttt code. I'll tell you

Astrobytes: :grin:

jacek: https://www.youtube.com/watch?v=dQw4w9WgXcQ

Astrobytes: Yeah, that kinda thing can make a difference jacek

jacek: some people may read the code

leojean890: 120k rollouts is enormous ;)

AntiSquid: humongous

darkhorse64: The engine is so simple

jacek: oh, never did true avx. maybe i should start

darkhorse64: avx does not help or I suck at it. My avx is slower

Astrobytes: It's not the easiest thing in the world

leojean890: ErisSMSO maybe good to go W1 as well^^

jacek: maybe Astrobytes wont be last after all

leojean890: EricSMSO *

leojean890: all W2 people are behind so..^^

Default avatar.png blanit: yo guys

Default avatar.png blanit: everyone*

AntiSquid: anyone

jacek: everypony

Default avatar.png blanit: i need some help here, gonna be testes in this site for a position. Whats the best path to do in 4 days?

Default avatar.png blanit: tested*

Astrobytes: jacek: nah, I expect that to be last until I fix my MCTS version

AntiSquid: upload an avatar, player botters

EricSMSO: I cross fingers

Default avatar.png blanit: x)

leojean890: you're not far Eric ;)

darkhorse64: boss 25.5

AntiSquid: that's why everyone who asks how to prepare fails blanit

Default avatar.png blanit: just want to pratice, dont be so judmental

Default avatar.png blanit: jugmental

AntiSquid: yes practice

Default avatar.png blanit: judgemental

darkhorse64: he is kidding you

AntiSquid: why the smiley then

AntiSquid: you can play clobber, see if you get at least wood 1

Default avatar.png Tuo: that is some evil advice

darkhorse64: practice puzzles

AntiSquid: if you want to pass a test prepare for the worst, nothing evil

Default avatar.png blanit: yup doing some puzzels was just asking if there was some path of something

AntiSquid: do the path on the landing page

darkhorse64: There is the quest map

leojean890: practice puzzles or reach gold on multis^^

EricSMSO: Yes ! Now let's try to uncomment #pragma

leojean890: gg ;)

darkhorse64: Why uncomment ?

Default avatar.png blanit: ty for the help!

Scarfield: Astrobytes behold my superiot paint skills https://prnt.sc/10nithg

EricSMSO: Because I forgot to uncomment itat first run

AntiSquid: try gimp it's free Scarfield

darkhorse64: What a serious kick!

Default avatar.png Kaukdsv: Hi

Default avatar.png Kaukdsv: Is there someone here now?

jacek: maybe

Scarfield: potentially

Default avatar.png Kaukdsv: :(

Default avatar.png Kaukdsv: What language do you use/know?

AntiSquid: why singular ?

Astrobytes: Scarfield: Hahaha! My dude. I will change my avatar immendiately :D

Scarfield: xD

Astrobytes: Or immediately.

AntiSquid: Scarfield starting his pimp my cg avatar show soon

struct: The more I code the less I know

Scarfield: i am the artist of 4 now i think

darkhorse64: Kaukdsv: C++. Python is also very popular here

leojean890: python, easier.. C++ more powerful

Default avatar.png blanit: no go?

struct: More important than knowing a language is knowing how to program

leojean890: go less known

Astrobytes: What struct said. 100%

AntiSquid: JavaScript is my favourite because so many people hate it while I like it.

Astrobytes: When you know what's happening behind the scenes, you can learn most languages fairly quickly

darkhorse64: As people say, use the right tool, the one you are confortable with and appropriate to the tasks. You have an ample choice of 25 (27?) languages

Default avatar.png blanit: is good to know to know general programming but langagues and diff purposes and specifics so its also good to focus on a few

Default avatar.png blanit: serve not and sry

Default avatar.png blanit: but yeah first focus on learn to program

AntiSquid: hey Scarfield just a suggestion/challenge, make cover arts for clobber / paper soccer / breakthrough and have them accepted :P

AntiSquid: art *

jacek: :3

AntiSquid: i mean without it nobody will even notice there's a football game

Scarfield: maybe, but i make these silly avatars for the chuckle, if i were to make coverart for games, it would probably have to be more serious

jacek: try one for tvc

AntiSquid: it's ok, just charge them money for it

Scarfield: there was mention of a pretty cool sketching tool a few weeks ago, not gimp though

AntiSquid: paint 3D ? :P

Scarfield: ew, you cannot improve paint

AntiSquid: sketchbook ?

Astrobytes: Krita?

Scarfield: krita yes

jacek: made in kotlin?

AntiSquid: oh krita is available on ubuntu too

darkhorse64: Astrobytes has lost 1st last place

AntiSquid: where

AntiSquid: clobber?

Astrobytes: Oof.

Astrobytes: Not for long if I go by recent experience :P

darkhorse64: Give some tips to EricSMSO

Astrobytes: I only give tips if you're stuck in the lower league :D

Astrobytes: And if you can give me good ones in return :P

darkhorse64: Fast bitboard engine, MCTS, solver

Astrobytes: I know all that

darkhorse64: I have no heuristic at all

PatrickMcGinnisII: tmi, inserting your tips into the weak

Astrobytes: I just haven't finished writing my MCTS. I planned to try EPT first

jacek: curious how ms' meta turned out

jacek: for ept you need heuristics :c

Astrobytes: Who you calling weak Patrick. darkhorse can insert his tips into whomever he likes :P

Scarfield: just the tip?

Astrobytes: jacek: there are heuristics

PatrickMcGinnisII: fingers, ===) whatever...tmi

leojean890: I'm keeping my alphabeta for now and trying stuff xD

darkhorse64: I try to keep my integrity

Astrobytes: And his meta was not great iirc jacek

PatrickMcGinnisII: sry ;)

darkhorse64: I have two kids: that's enough

Astrobytes: Not like you to lower the tone at all Patrick :P

Astrobytes: hahaha

PatrickMcGinnisII: tomorrow is st. patricks day, I'm warming up

Astrobytes: leojean890: alphabeta is enough

Astrobytes: for the next league I mean

kovi: why clobber is more popular than chess?

Astrobytes: chess is far more involved

leojean890: yeah but I have to give up python and improve my eval xD

Astrobytes: clobber sim is 5 minute job

AntiSquid: ppl hate castle

leojean890: chess implies mass investment

darkhorse64: 27 people: not that popular

leojean890: you need more time

leojean890: so maybe one day more people will have time

Astrobytes: Why does breakthrough have so many people?

leojean890: because it's been available for long

leojean890: like vindinium

leojean890: dots and bots it's because it's user friendly and looks easier

Astrobytes: Hm. Perhaps darkhorse64 should add a boss so it can be POTW and get even more.

darkhorse64: Simple engine, some tactics ?

darkhorse64: It has already been potw

Astrobytes: How did that work?

darkhorse64: Quite well. It doubles the number of people

darkhorse64: doubled

Astrobytes: Yeah, but they can't get the achievement because of only one league

darkhorse64: It was pre quest map

Astrobytes: Ah yes, ofc

jacek: :soccer: was also potw, during contest :unamused:

leojean890: potw helps, but some were potw and are still unpopular

AntiSquid: made me giggle, i still remember

leojean890: blocking or fireworks don't have many people yet

darkhorse64: it did not work for fireworks and tryangle

leojean890: penguins or D&B or 2048 were hugely valorized

leojean890: by POTW

Astrobytes: blocking movegen is insane and fireworks requires some time to understand. Tryangle is a game that requires some invested time

darkhorse64: ^

leojean890: I didn't do tryangle and blocking for the moment btw

PatrickMcGinnisII: i think clobber can be optimized for play using a number generator

darkhorse64: ?

PatrickMcGinnisII: it would be hard to find

leojean890: yeah Astrobytes they are not easy

AntiSquid: fireworks is only hard because of the inputs

leojean890: blocking huge branching, chess idem, tryangle idem...

Scarfield: idem?

leojean890: idem = same for

Astrobytes: It's like saying what you've just said

Scarfield: Indiana Department of Environmental Management

Scarfield: never seen that expression before

Astrobytes: Blocking huge branching, chess huge branching, tryangle etc etc

leojean890: idem maybe is french idk

Scarfield: latin

leojean890: but I use this in french ;)

kovi: maybe not all requires game tree...

Astrobytes: I've used it in writing papers and stuff

leojean890: blocking huge branching, same for chess, same for tryangle...

kovi: altough im still having trouble beating boss with no tree...

leojean890: maybe heuristics without game tree may be ok

kovi: chess

jacek: huge branching factor isnt problem. making a sim is

leojean890: chess maybe depth 2 would be ok with good eval for W1 ?^^

Theino: blocking huge branching, chess Indiana Department of Environmental Management, tryangle Indiana Department of Environmental Management

leojean890: Theino trolling ;P

Scarfield: how close to the boos kovi?

jacek: afaik chess boss is 1ply material

Scarfield: and the boss

Astrobytes: Or maybe weaker eval and more depth

Theino: we Americans are serious about our Indiana Department of Environmental Management

leojean890: huge branching may be a problem, because needs to deal with it^^

Astrobytes: yeah jacek, material eval with 2-3 depth should be enough (I think)

Scarfield: iirc re curse said depth 2 material for chess boss

leojean890: with heuristics for example

EricSMSO: So Astrobytes, give me the tips; please

kovi: scarfield: almost 2. im still <40%

jacek: well i advanced league when i hadnt castling or en passant yet

Astrobytes: EricSMSO: You don't get any since you're no longer in the bottom league :P

Scarfield: ye me too, and only 1 ply eval

AntiSquid: k what's quickest way to upper league Astrobytes

PatrickMcGinnisII: <--1D board eval, if you can't beat my chess bot u aren't trying

Astrobytes: AntiSquid: good eval

Scarfield: boss is boosted again i guess, but nice to see another chess player :)

AntiSquid: (╯°□°)╯︵ ┻━┻

Astrobytes: AntiSquid: think outside the box

AntiSquid: for clobber you mean ?

Astrobytes: The eval may not be the most intuitive

Astrobytes: Yes.

AntiSquid: just wanted to know if there's a quick way, doing something else atm

leojean890: there are some papers which could help ^^

leojean890: I saw them really fast

Astrobytes: Actually, to advance to next league I would ignore the papers

kovi: i need to add knight fork/check

leojean890: only a powerful MCTS with many sims;p

Astrobytes: I made it with alphabeta

kovi: that is too strong...and its not immediate effect

jacek: spoon?

Astrobytes: spork jacek

leojean890: or .. a powerful alphabeta with many sims and a good eval

Astrobytes: Now you're talking

Default avatar.png Coder_DaYan: http://chat.codingame.com/pastebin/17ba16b8-db73-4c3c-b8ee-2a1c46c0326f

Astrobytes: alphabeta, some move ordering, TT

leojean890: my eval is bad, mostly checking the number of pawns which can move per player^^

Default avatar.png Coder_DaYan: why does this code not work?

leojean890: (not the number of moves)

Astrobytes: That's a useful addition

AntiSquid: because you wrote it twice Coder_DaYan

leojean890: it's a very light eval^^

Astrobytes: There's something else you can evaluate too leojean890, look at the neighbourhood of your pawns

Scarfield: yea, you want your pawns to live in a good neighbourhood

Default avatar.png Coder_DaYan: no, I just copied it wrong AntiSquid

leojean890: number of neighbors which are my own/adv/empty pawns ?

Astrobytes: I'll let you work it out leojean890

leojean890: ok hehe

Astrobytes: ;)

Scarfield: you arent on the leaderboard though leoIdem

AntiSquid: sell them at the pawn shop

AntiSquid: ?

leojean890: I'm 2nd W2 Scarfield

jacek: Coder_DaYan and what puzzle is that

Scarfield: xD thought you were talking chess

leojean890: clobber;)

Default avatar.png Coder_DaYan: It`s the Horse-racing Duals Puzzle

leojean890: chess, I'll see that later, it takes too much time !

Astrobytes: ^

Default avatar.png Coder_DaYan: The code passes the first and second tests

Default avatar.png Coder_DaYan: but not the third

Astrobytes: And better to bitboard chess from the start rather than start with arrays and whatnot

jacek: as i copied, the code doesnt pass any test o.O

Default avatar.png Coder_DaYan: http://chat.codingame.com/pastebin/001f6a6b-d9e7-4089-a40c-cc02dd0c7bd2

Default avatar.png Coder_DaYan: this code?

AntiSquid: optimize it

jacek: ah oops, not this puzzle ^^

jacek: yeah, code works but is slow

AntiSquid: check time complexity

jacek: you have two loops, N*N operations

Astrobytes: Ditch a for loop and figure out how to save some info that you can use

Default avatar.png Coder_DaYan: and what info could I use with just one for loop

Astrobytes: That's what you have to figure out

jacek: you have hints on the left

Astrobytes: leojean890: either do some insane pruning or don't use python :P

Default avatar.png Coder_DaYan: OK thank you

Suez17: who finished the Bender exercise ?

Default avatar.png Coder_DaYan: I think I have an idea that could work: do you have to sort them all according to size and then only compare the neighboring numbers?

Scarfield: good idea

Default avatar.png Coder_DaYan: would that work?

Scarfield: depends on how much time your sorting takes, but yes

Astrobytes: Try it and see ;)

Default avatar.png Coder_DaYan: OK, thank you very much for the help, I'll give it a try

leojean890: Astrobytes I know about python xD but need a beter eval as well :p

Astrobytes: leojean890: fair point :)

jacek: i know this eval: if (win) +inf else if (lose) -inf

leojean890: better*

Scarfield: else ±inf

leojean890: Astrobytes my eval is : 10*(nbPawnsThatCanMove - nbEnemyPawnsThatCanMove) + nbValidMovesAtMyMaxDepth - nbEnemyValidMovesAtHisMaxDepth

leojean890: I'll think about your idea of watching my pawns neighborhood

Default avatar.png Tuo: i did defended pawns when i was still evaluating boards

Astrobytes: leojean890: yes, prioritise the pawn neighbourhoods in the eval though

Default avatar.png Tuo: as in pawn that can move and has own pawn neighbour

leojean890: defended ?

leojean890: oh ok

leojean890: so if the enemy eats you..

leojean890: you can eat him back

Default avatar.png Tuo: y :)

Astrobytes: I am saying nothing further. tric paid for this info with a trade. You get nothing for free :P

leojean890: because you have a own neighbor

leojean890: XD

jacek: he paid for paper?

leojean890: I saw this drawing in a paper

leojean890: a drawing showing how they studied the problem

leojean890: and they considered this case

leojean890: analyze if you can eat back

Astrobytes: Yeah, don't think too deeply is the advice I would give you right now.

Astrobytes: It's simpler than you think.

Astrobytes: To get to the next league I mean.

leojean890: yeah ;P

leojean890: or MCTS xd

Astrobytes: Yes indeed

Default avatar.png Coder_DaYan: thank you so much. I have now tried it and it worked well

Astrobytes: Coder_DaYan: excellent :)

Astrobytes: Now use that kind of thinking in future puzzles, it will help

Scarfield: :muscle:

Default avatar.png ENTITY303: cool

Default avatar.png ENTITY303: awesom
