MiyamuraIzumi: Hello guys

holyterror: hi

Default avatar.png zaldis: Hi guys!:wave:

Default avatar.png XanderGaldones: what's up!

derjack: ttt eh

Default avatar.png mailbox: this website is good for learning but def urges you to do bad practices lol

Default avatar.png mailbox: i almost named my variable "a" when i was programming normally lol

derjack: codegolf isnt for good practices

derjack: heck most stuff here isnt for good practices. my code here is hackatonish

Uljahn: this site is about learning dirty hacks :smiley:

Default avatar.png mailbox: mhm lol

Uljahn: e.g. how to fit NN in 100k or to use bitboards and AVX

derjack: bitboards arent dirty :o

Default avatar.png mailbox: i mean, when are you going to need to micro 1 byte

Default avatar.png mailbox: 10 bytes even

derjack: bitboards are for speed. NN quantiozation for speed also, due to cache coherence and whatnot. but normally they would be encapsulated in nice classes etc.

Default avatar.png DeadlyFeature: Hello guys

Default avatar.png sgprtz: hi!

Default avatar.png Serjongo: hi

Default avatar.png Chubz: hi

derjack: c-c-c-com...

islander4059: henlo

chop-chop: Hi

ProCoder03: What is an optimal time in space race ??

ProCoder03: *search race

ProCoder03: and what is that collision time in it ??

derjack: probably lower than 1st

ProCoder03: :unamused:

TimothyAlexisVass: Why did this stop further code? :\

ProCoder03: ???

MiyamuraIzumi: 492180 Points

TimothyAlexisVass: if(row.split``.every(c=>c=='#')){b=true;break;}

TimothyAlexisVass: even if it evaluated to false, the code after didn't run...

TimothyAlexisVass: Will it break if row is empty or something?

ProCoder03: MiyamuraIzumi, What are you talking abt..... CG points...

chop-chop: wrap into try{}catch(e){/*you-code*/}

chop-chop: probably there are some error

MrBest: Hello guys

ProCoder03: :wave:

Default avatar.png TaPadPo: Hi

Default avatar.png Plourfi: yo

Default avatar.png Plourfi: pouet pouet

MiyamuraIzumi: ProCoder03, I just excited on my improvement on CvZ, this is the new point :D

derjack: oh my

Default avatar.png Paper_Was_Taken_Sad: script no worke

Default avatar.png Paper_Was_Taken_Sad: print("help')

chop-chop: "help"

Default avatar.png C26_1: hello

Default avatar.png C26_1: I'm gonna ask a question

derjack: hm?

Default avatar.png C26_1: Does using a lot of variables make you bad at programming language

derjack: no

derjack: sometimes you need a very lot of variables

Default avatar.png C26_1: I don't have exprience with any real work, but at least knowing some coding

Default avatar.png C26_1: Cool

Default avatar.png C26_1: Thank you for answer my question

Default avatar.png C26_1: At least if you do some simple code, you don't need a lot of them

Default avatar.png C26_1: For example:

Uljahn: just make sure your variable names are meaningful and you're good

Default avatar.png pikachutiya: i honestly find it better if there are multiple clearly defined variables, keeping in mind that you only use variables when its absolutely necessart

Default avatar.png pikachutiya: necessary*

derjack: oh my that turtle is about smits in c4

Default avatar.png C26_1: Um

Default avatar.png C26_1: Im gonna copy my post from Reddit (Bc I'm inventing Base-Divide notation)

Default avatar.png C26_1: http://chat.codingame.com/pastebin/55bdf0df-adec-4506-9a76-d60ce3c7e100

Default avatar.png C26_1: Oops, the text is so large that it is meaningful to paste them as pastebin

derjack: any question?

Default avatar.png C26_1: So I'm inventing something called Base-Divide Notation (Or you can called it as Base-Power Notation bc it's related)

Default avatar.png C26_1: the things that it'll do is store a very very large to some small way

Default avatar.png C26_1: large numbers*

Default avatar.png C26_1: The notation in general is:

Default avatar.png C26_1: (n1,n2,n3,.....,nk)b

Default avatar.png C26_1: where k is the length of the notation, and b is the base

Default avatar.png C26_1: Note to know here:

Default avatar.png C26_1: 1. You cannot have a digit in number that is larger to the base (EX: 1234, no digits in 1234 is larger the number 10 - the base)

Default avatar.png C26_1: 2. You only use that notation for some very large and unusual base like base 13, base 41, base 100

Default avatar.png C26_1: 3. Just to know, writing wrong digits in notation isn't "wrong" but to keep base analysis clear, you just have to do that

darkhorse64: ProCoder03: what do you mean by optimal ? Shortest ? Something you can reach with a moderate effort ? The collision time is the time at which you reach a checkpoint during your turn. A turn duration is 1s

Default avatar.png C26_1: 4. You can plugin real numbers in digits of the notation, as long as the digits smaller than the base, and you know the converting formula from any base to base 10

Default avatar.png C26_1: Ok, done the introduces

Default avatar.png C26_1: Back to the conversation

Default avatar.png C26_1: We write the notation with the open bracket first "(" , with the following "|" for every digits in the numbers. After that, you use the closed bracket ")" to close the number, and finally plug the base as a number

Default avatar.png C26_1: For example:

Default avatar.png C26_1: (|20|31|42|)56

Default avatar.png C26_1: Or

Default avatar.png C26_1: (|12|32|45|)100

Default avatar.png C26_1: Ok, done the notation

Default avatar.png C26_1: How to convert the "number" in base "b" to base 10 for our human-purpose reading

darkhorse64: You have a clash of code subject with this notation

Default avatar.png C26_1: @darkhorse64, what clash tho?

darkhorse64: short time span (5 min) problem solving

darkhorse64: https://www.codingame.com/multiplayer/clashofcode

Default avatar.png C26_1: formula for converting base "b" to base 10: https://slidetodoc.com/beyond-base-10-nondecimal-based-number-systems-what/

darkhorse64: You can make contributions to CoC too

Default avatar.png C26_1: Ok

Default avatar.png C26_1: But can I typing the text fully in this chat

Default avatar.png C26_1: I'll do now

Default avatar.png C26_1: So back to notation converting

darkhorse64: A wall of text will be turned automatically to a pastebin

Default avatar.png C26_1: It just as easy as doing carry sums in elementary schools so don't worry if you scare math or hardcore one

Default avatar.png C26_1: Example this number:

Default avatar.png C26_1: (|13|29|14|)30

Default avatar.png C26_1: You want to converting that number into base 10 right?

Default avatar.png C26_1: I don't know the general step, so I'm just writing step for this EX, just to so if you can figure out

Default avatar.png C26_1: Step 1:

Default avatar.png C26_1: Divide 14/30: remainder: 14, carry sums: 0

Default avatar.png C26_1: Step 2:

Default avatar.png C26_1: Wait

Default avatar.png C26_1: That's the wrong step

Default avatar.png C26_1: Sorry

Default avatar.png C26_1: Step 1: Compute 13*30^2 + 29*30^1 + 14*30^0

Default avatar.png C26_1: Done

Default avatar.png C26_1: The result is 12584

Default avatar.png C26_1: Sorry again, Carry sums and remainder is in part 2: Rewriting the wrong notation to the right one

Default avatar.png C26_1: Part 2: Rewriting the wrong notation to the right one


MiyamuraIzumi: http://chat.codingame.com/pastebin/fcf34813-7376-4c9b-bafa-3179f3846e2f

Default avatar.png C26_1: So, there are only 2 ways to writing the wrong notation, either writing less symbols as it needed, or if the digit is larger or equal to the base

MiyamuraIzumi: nice haha

Default avatar.png C26_1: Example

chop-chop: how to open such links http://chat.codingame.com/pastebin/fcf34813-7376-4c9b-bafa-3179f3846e2f

Default avatar.png C26_1: (|30

Default avatar.png C26_1: (|30|12|14|)21

Default avatar.png C26_1: This is a wrong notation

MiyamuraIzumi: just text alot

Default avatar.png C26_1: We need to rewrite it, as we need base analysis to be neutral

MiyamuraIzumi: chop-chop

MiyamuraIzumi: http://chat.codingame.com/pastebin/f63e7b4f-ade1-4af3-9021-9e575de6f0b3

Default avatar.png C26_1: Step 1: Compute 14/21, remainder = 14, carry sums = 0

Default avatar.png C26_1: Step 2: Compute 12/21, remainder = 12, carry sums = 0

Default avatar.png C26_1: Step 3: Compute 30/21, remainder = 9, carry sums = 1

Default avatar.png C26_1: Step 4: Compute 1/21, remainder = 1, carry sums = 0. End digits

Default avatar.png C26_1: Done

Default avatar.png C26_1: Rewrite (|30|12|14|)21 as (|1|9|12|14|)21

Default avatar.png C26_1: So that's it

Default avatar.png C26_1: End of the notation conversation

Default avatar.png C26_1: Note: You only need use that notation if you stored a super large number ino small numbers

chop-chop: C26_1, it looks interesting!

chop-chop: http://chat.codingame.com/pastebin/ca2e9530-afe4-4a92-86dd-43bd1033372c

Default avatar.png C26_1: In computer science, you can use that notation as an array, where the last number in array is the base, all other are just digits

Default avatar.png C26_1: If you ever use my notation in math paper or the other way around, just writing this line of text: "The Base-Divide Notation is invented by user C26_1 in codingame.com"

Default avatar.png C26_1: I don't need (money, or credits in general)

Default avatar.png C26_1: Soooooo....

Default avatar.png C26_1: The ends.

chop-chop: http://chat.codingame.com/pastebin/17702314-3692-4bec-89c0-c0f1042fa0cf

chop-chop: @MiyamuraIzumi, I insert a long text and it was converted to link. But how to see content of this link?


Default avatar.png Lanfeustdedeux: Hello guys! Do you know if there are any tools for debuging?

derjack: most decent IDEs allow for debugging

derjack: on codingame, you can print values to stderr

Default avatar.png Lanfeustdedeux: Oh, ok thanks

derjack: what language

Default avatar.png Lanfeustdedeux: I'm using python, but I guess you just meant to use print("....", file=sys.stderr)

Default avatar.png Lanfeustdedeux: I realised that there was an comment that was automatically generated that said we could use that for debugging x)

Default avatar.png Lanfeustdedeux: I should have RTFM as we say

derjack: nah, its always better to ask in chat than to read the statement :v

Default avatar.png me23: credit

chop-chop: ^ true

MiyamuraIzumi: gooooooo

KalamariKing: stoooooop

Default avatar.png JacobTheCoder: hi:)

KalamariKing: hey!

MrBest: hey THERE!

Default avatar.png JacobTheCoder: i thought it said mrbeast xD

Default avatar.png JacobTheCoder: anyone got tips for C++?

KalamariKing: c-- is better smh

Default avatar.png JacobTheCoder: fair enough

Default avatar.png JacobTheCoder: havent really tried it

derjack: oO

Default avatar.png GoodGuss: I want to learn to write code, but I think I am not smart enough

Lord_Binary: everyone can learn to write code, but don't expect it to be fast and easy to learn

Lord_Binary: as long as you put in the time and effort, I am sure you will learn :)

automata: I am playing clash of code after not playing it for a very long time. People seem not to share their code mostly these days. Maybe it is just my impression, but it used to be very collaborative back in the day. Top players used to share and now it is the opposite.

Wontonimo: GoodGuss, learning to code is like learning to read. It takes daily effort over a long time. And like reading, it can be fun if you choose

Wontonimo: maybe play the challenges https://www.codingame.com/training instead. There you can see lots of shared solutions

Wontonimo: Lord_Binary ^^

Wontonimo: oh, sorry, that was meat for automata

Default avatar.png C26_1: Does fast code rely on programming language (like C++ vs Python) or Algorithms (Like Binary Search or Linear Search)

Wontonimo: both

Default avatar.png C26_1: Ok

Default avatar.png C26_1: I need to learn C++ quick

Default avatar.png C26_1: Because I knew that C++ is a lot faster than Python

Wontonimo: if you have to use a language, then you can improve speed using efficient data structures

Default avatar.png C26_1: But its syntax is horribly hard to read or even translate it to Python

Default avatar.png C26_1: What a cool trae off after all

Wontonimo: I'm not trying to talk you out of learning C++, but why do you want code to be a lot faster?

Default avatar.png C26_1: trade off*

Uljahn: how fast do you need your code to be? in most cases python is more than enough

Default avatar.png C26_1: um ok

Wontonimo: +1 Uljahn

Default avatar.png C26_1: At least if runtime is not larger than 1 seconds for any function

automata: Wontonimo, my point was that people should share their code. Especially if they win.

Uljahn: it all depends on data though

struct: learn logic first

Wontonimo: +1 ^^

struct: you dont need to speed if you dont know how to code

struct: dont need speed*

Default avatar.png C26_1: @struct, good quote

automata: C++ is not a lot faster than Python per se


struct: You dont want to learn a language, you want to learn how to code

struct: if you are a begginer

DamCoder: But u need "Speed" - if u want to code faster :o

automata: But to be constructive, you can use Cython

Default avatar.png C26_1: I mean programming language are for human reading after all, so don't use list comprehension or if-trick in python if you want your code need to be readable

Default avatar.png C26_1: I have a idea

Default avatar.png C26_1: if you make your code to be fast and also readable to your team, then

Uljahn: i use numpy and numba when i want my python to go faster

Wontonimo: Here is an example https://www.codingame.com/ide/puzzle/the-lucky-number A brute force attack on this problem will time out for any language. My plain python solution that uses some logic takes 0.3 milliseconds

struct: i use c++ when i want my c++ to go faster :)

Uljahn: you mean pragmas

Default avatar.png C26_1: Make your function store in 1 file where you do the readable one and send it to your team, and make the fastest one to your own

Default avatar.png C26_1: Then use fastest function to public if you ever post it in Github

derjack: or use OOP, encapsulate parts of codes into functions and classes. if there is critical part of code that needs to best fast but not readable, then only that part will be unreadable, but you can still use comments there

struct: if you want readable code use perl

derjack: and avoid using structs ~

eve_va_hooves_the_king_of_wifes: hm

eve_va_hooves_the_king_of_wifes: cool

eve_va_hooves_the_king_of_wifes: im bored, anyone wanna chat about games and anime?

derjack: that would be quite offtopic for this chat, wouldn't it?

eve_va_hooves_the_king_of_wifes: hmmm... yea but im asking if anyone wants to

eve_va_hooves_the_king_of_wifes: and im really bored

automata: not if talk about the codingame :joy:

eve_va_hooves_the_king_of_wifes: hmmmmmmmmmmmmmmmmmmmmmmmmm

eve_va_hooves_the_king_of_wifes: ok

chop-chop: Do we have any clash of code about anime related theme? >.|.<

eve_va_hooves_the_king_of_wifes: HMMMMMMMMMMMMMMMMMMM??????


eve_va_hooves_the_king_of_wifes: boys and girls, we have a job to do

xspeedasx: cwash of cwode uwu

eve_va_hooves_the_king_of_wifes: a furry?

xspeedasx: in a blender

eve_va_hooves_the_king_of_wifes: hm

eve_va_hooves_the_king_of_wifes: well time to make a furry account

derjack: are bronies furries?

eve_va_hooves_the_king_of_wifes: nah

eve_va_hooves_the_king_of_wifes: i can say that cuz im a furry and bronie and a weeeb

xspeedasx: hmm no judgement, most of them probably are

derjack: :scream:

eve_va_hooves_the_king_of_wifes: hm

eve_va_hooves_the_king_of_wifes: illl be back laters

eve_va_hooves_the_king_of_wifes: seee ya boys and goirls uwu

Astrobytes: This chat sometimes makes me feel so dead inside when I read it back. Grim af.

derjack: yeah :unamused:

derjack: and smits still didnt notice hes not first in Y

xspeedasx: at least its not about antivax or flat earth :D

xspeedasx: that would be grim

Astrobytes: I'm sure there'll be some of that at some point too.

struct: just need to open twitter

Default avatar.png Bobbelo: Hey guys, when you are doing the practices, is there any way to see what the input is for the test cases?

Default avatar.png Bobbelo: Its really annoying that I can't find it because knowing what the inputs are will make it easier to debug

Default avatar.png Bobbelo: Nevermind, found it

xspeedasx: there's a "list" button to the right of TEST CASES | CUSTOM |

Default avatar.png Bobbelo: thanks speed

xspeedasx: too slow :D but np

xspeedasx: i like to take the inputs and use them to solve it in IDE then just copy-paste the code back to CG

xspeedasx: if its a puzzle

Default avatar.png Bobbelo: Would there be a way for me to ask for help here? is it okay if I just paste code?

xspeedasx: use pastebin :D

Default avatar.png kumabearr: use carbon :p

Default avatar.png kumabearr: https://carbon.now.sh/

Default avatar.png Bobbelo: https://pastebin.com/cv6tBf87

chop-chop: @kumabearr, carbon - its nice one, thx

Default avatar.png kumabearr: :)

struct: Bobbelo

Default avatar.png Bobbelo: Yeah?

struct: You turn negative into possible

struct: and then save it has negative

struct: your comparison is always checking the positive value vs negative

Default avatar.png Bobbelo: What?

chop-chop: how to mention some one?

struct: if unsign_temp < closest_temp:

struct: This part

Default avatar.png kumabearr: chop-chop

struct: if last temperature was -12

struct: you stored -12

Default avatar.png Bobbelo: My goodnes.

Default avatar.png Bobbelo: Thank you so much

struct: you understood?

Default avatar.png Bobbelo: yeah, but now I'm completely lost on how to fix it

struct: do you know abs?

xspeedasx: suggest to have another closest_temp but with a sign. ala closest_real_temp and assign t to it when you assign unsign_temp to closest_temp

Default avatar.png Bobbelo: I did it! :D

kumabearr: :clap:

Default avatar.png Bobbelo: https://pastebin.com/dm8gYc5x

Default avatar.png Bobbelo: Thanks for the help guys

Default avatar.png Bobbelo: Now I can rest peacufully

Default avatar.png Bobbelo: Peacefully*

Default avatar.png Lanfeustdedeux: Hey guys! Do you know if we can battle a friend?

Default avatar.png Lanfeustdedeux: In "Coders Strike back" sorry

Default avatar.png Lanfeustdedeux: The game with the pods racing x)

Wontonimo: yeah, if they are in the same league

Wontonimo: you can remove the boss and then add them

Wontonimo: you can then share the replay with them

struct: only if they are on top 1k of the league though

Wontonimo: can't you search by name struct?

struct: no

struct: it will still only get based on the 1k

Wontonimo: Lanfeustdedeux - it looks like your bot is broken and isn't reading the new data for gold league. You can get the new template by clicking the circle arrow in the upper right of the IDE

Wontonimo: then you can get your old code from history and copy it in where it is expected.

Wontonimo: you will immediately jump 1000 ranks just by having working code that simply flies directly to the next checkpoint

Default avatar.png JacobTheCoder: hi

Default avatar.png JacobTheCoder: im new to coding and want to know the best way and what type (C++, JS, etc.) to code

struct: both have their uses

Default avatar.png JacobTheCoder: heh

Default avatar.png JacobTheCoder: what would be the best for like addons or whatever

struct: what do you mean by addons?

Default avatar.png JacobTheCoder: lemme rephrase that lol, for games

Default avatar.png JacobTheCoder: so like say for instance shooters, car games ya know?

struct: both work

struct: js for mostly browser

Default avatar.png JacobTheCoder: okay

struct: c++ for desktop

Default avatar.png JacobTheCoder: ahhh

Default avatar.png JacobTheCoder: where is the best place to start with no experiance

Default avatar.png JacobTheCoder: experience

Wontonimo: there is a really good youtube channel called "the coding train"

Wontonimo: he does some really good intro to programming videos

Wontonimo: he has over 1000 instructional videos on programming

Default avatar.png JacobTheCoder: cant really watch it rn cause im in school but ill watch it when i get home

struct: I remember seeing some of his videos long ago

Default avatar.png JacobTheCoder: so like is he #1recommended?

Wontonimo: if you have zero experience programming, you can play with coding concepts using https://scratch.mit.edu/

Default avatar.png JacobTheCoder: ah

Default avatar.png JacobTheCoder: gtg

Wontonimo: that is a fun way of starting to visualize coding structures

Default avatar.png JacobTheCoder: seeya

Default avatar.png JacobTheCoder: yeah

Wontonimo: later

MONIGMA: hey

Wontonimo: :wave:

struct: I see you made it to gold Wontonimo

Default avatar.png Pinggo: please teach me to use js

Default avatar.png Pinggo: how to use js

MONIGMA: You don't know how to use JS

Default avatar.png Pinggo: i newbe

struct: 0=="0" true

struct: All you need to know

MONIGMA: me too but I use Python and Java

Default avatar.png Pinggo: i'm stil confuse. cos my english is not good

struct: Pinggo usually you wont find someone that will teach you a language

Default avatar.png Pinggo: im didnt go to college too

Default avatar.png Pinggo: too poor eheheh

struct: You dont need to go to college to learn js

struct: First challenge to learning js is learning how to google

struct: Then you find a tutorial that suits you

struct: Some people like videos, some like books, some learn by doing

Default avatar.png JacobTheCoder: hi

Default avatar.png JacobTheCoder: im back

Default avatar.png JacobTheCoder: but not for long cause i have to do work D:

Default avatar.png JacobTheCoder: :(

Default avatar.png Pinggo: okay

Default avatar.png Pinggo: i'll try to watch youtube

struct: good luck

Default avatar.png Pinggo: thanks mr struct

Wontonimo: if you are total newbe, try scratch.mit.edu

Default avatar.png Pinggo: this is my first day open this web

Default avatar.png Pinggo: thanks sir

Default avatar.png Pinggo: so im tottaly newbie

Wontonimo: yeah struct, thanks for noticing

struct: are you aiming for legend?

Wontonimo: i've got a major bug and i also want to switch to minimax or mcts. those two things combined i'm confident will get me to legend in tron

struct: do you use bitboards?

Wontonimo: not yet. i'm going to see if i can get away without it for now

jacek: wgat game

Wontonimo: it's a large board with multiple players. makes life simple to just use uint8_t

Wontonimo: Tron !

struct: yeah

Default avatar.png zacdave: hello world

struct: Olá mundo

Wontonimo: and if you can get away with not saving the board, then it can be mostly all in L1 cache anyway

struct: should still fit in L1

Wontonimo: i was thinking DFS implementation of Minimax with iterative deepening. Are you working on tron anymore and what's your plan?

struct: no

struct: I only have been working on "dumb" games

struct: Games where I dont need to think

Wontonimo: :)

jacek: like amazons :v

struct: jacek bot still undefeated :(

Wontonimo: yeah, i hear that struct. I did that for about 4 months.

Wontonimo: helping so many people with PID really got my pid game improved and helped with space shooter

Default avatar.png JacobTheCoder: hoi

Wontonimo: hey Jacob

Default avatar.png JacobTheCoder: im dying rn xD

Default avatar.png JacobTheCoder: but anywho ima go ahve fun coding goodbye :)

Wontonimo: sorry to hear. call 1-888-1hearse

struct: hf

Default avatar.png JacobTheCoder: lol

Default avatar.png JacobTheCoder: idk where to start

jacek: from the beginning

Default avatar.png JacobTheCoder: :O no way

Default avatar.png JacobTheCoder: this feels like a populated discoed server lol

Default avatar.png JacobTheCoder: discord*

struct: you should come here during a contest then

Wontonimo: it's almost too much during contests

Wontonimo: i get very distracted

struct: Ill ban you from chat if you dont want to get distracted :p

Wontonimo: i'm here now and being distracted ;)

Astrobytes: instaban offence

struct: this ludii games thing is crazy, I should make a module for sdk that can do this, but I think its way too far from my knowledge

Astrobytes: Could be an interesting side project, you can only gain knowledge from it right

struct: Yeah, also their code is open source

struct: this is their code for breakthrough

Astrobytes: indeed

struct: https://ludii.games/lud/games/Breakthrough.lud

Astrobytes: Yeah, I've checked it out before

jacek: !

jacek: general game playing game?

Astrobytes: framework

jacek: i mean new game for CG

jacek: no need for statement, the game will be generated on the fly

jacek: and rules provided in 1st turn

Astrobytes: lol

Astrobytes: sounds like a plan

struct: gl jacek

struct: you must do it now

Astrobytes: ^

jacek: good. writing the statement is the hardest part anyway

struct: I think everyone can agree to that

jacek: or does ludii generate the statement based on rules? :thinking:

struct: nah

Astrobytes: modify the Automaton to generate statements

jacek: Automaton2000 eh

Automaton2000: even though it is not a language

eve_va_hooves_the_king_of_wifes: IM BACK!!


jacek: uwu

eve_va_hooves_the_king_of_wifes: but im gonna go to another class

Astrobytes: Great.

eve_va_hooves_the_king_of_wifes: i hate art -_-

MONIGMA: art is greatOUCH!

eve_va_hooves_the_king_of_wifes: but thats u and others

MONIGMA: okee

eve_va_hooves_the_king_of_wifes: ill be back

MONIGMA: okay

eve_va_hooves_the_king_of_wifes: love ya lovely

MONIGMA: ooooookaaay

eve_va_hooves_the_king_of_wifes: be a good lil person BYEEEEEEEEEE! uwu

eulerscheZahl: i think that's enough okays

Astrobytes: Seriously...

MONIGMA: yeah

eve_va_hooves_the_king_of_wifes: lol

jacek: classes these days...

MONIGMA: Youre one to talk

eve_va_hooves_the_king_of_wifes: yup, they are fulled with people like me or like u

Astrobytes: Can you give it a rest please. This is not your classroom. This is not your playground.

eve_va_hooves_the_king_of_wifes: fine fine, ill take it down a few (to alot) of downs

MONIGMA: The code iis my playground

eve_va_hooves_the_king_of_wifes: see ya, i need to go to class, i shall be back

Astrobytes: Don't hurry.

MONIGMA: ok im in class right now

MONIGMA: HEhe

MONIGMA: bye everybody

Default avatar.png krazy-kenny: Cat

Wontonimo: vi

eulerscheZahl: vim

WWFYMN: can i say cum?

Astrobytes: You just did.

eve_va_hooves_the_king_of_wifes: -_-

eve_va_hooves_the_king_of_wifes: bruh

WWFYMN: can I?

WWFYMN: again

eulerscheZahl: no

WWFYMN: :(

Astrobytes: say it again and I'll kick you

WWFYMN: sad

eulerscheZahl: i had already typed the kick, still in my clipboard

eve_va_hooves_the_king_of_wifes: this dude is worser than me

WWFYMN: lol

eve_va_hooves_the_king_of_wifes: and i did ALOT of bad stuff

WWFYMN: not as bad as a certain failed artist?

eulerscheZahl: so, this yare contest... hard to test your bot when there are only 3 bots to play against. and other players only if they are online at the same time as you

struct: whats the contest euler?

Astrobytes: Say what?

eve_va_hooves_the_king_of_wifes: well im in art class rn

struct: focus on class

eve_va_hooves_the_king_of_wifes: cant

Astrobytes: or we'll kick you

eulerscheZahl: https://yare.io/d1/otqgv31hz2p3 that game is running live right now struct

eve_va_hooves_the_king_of_wifes: OKAY OKAY!

eve_va_hooves_the_king_of_wifes: we're doing alleys

Astrobytes: Hm. Somewhat annoying situation euler

eulerscheZahl: and it's more of a heuristic contest than a simulation. so you have to cover those corner cases yourself

Astrobytes: Kinda surprised you're bothering with it

struct: 0.6 ethereum

struct: o.o

struct: thats 10k $

eulerscheZahl: yeah, not bad. and only 30 players qualified for the finals

struct: When does contest end?

Astrobytes: Oh right.

eulerscheZahl: you can't join anymore

eulerscheZahl: and $10k?

eulerscheZahl: last i checked it was about 2k

struct: ah sorry

struct: yeah

struct: i had in brazilian currency

struct: sorry

struct: Similar $

Astrobytes: Still, wouldn't sniff at 2K

struct: but has an R before

eulerscheZahl: tbh that prize money is my main motivation right now

struct: i was shocked when i saw 18k

struct: gl euler

Astrobytes: Reais

Astrobytes: (the R)

struct: 1800€ is a good prize

Astrobytes: about £1500

eulerscheZahl: not like i really need the money. but i've never grabbed such a big prize before

Astrobytes: So if you win you'll be donating it to charity then :P

eve_va_hooves_the_king_of_wifes: im lookin for a alley that looks very dirty

Astrobytes: I'll kick you into one if you don't stop talking bollocks

Wontonimo: talk about coding, stay on topic, be respectful

eve_va_hooves_the_king_of_wifes: okay, how do i code a alley into a coding thing

eve_va_hooves_the_king_of_wifes: okay im done joking around, ill do my class

struct: Whats the reason for both players having to be online though?

Astrobytes: Poor design choices I suspect.

eulerscheZahl: it's a semi-bot contest actually

eulerscheZahl: you can edit your code while the game is running

struct: o.o

Astrobytes: interesting...

eulerscheZahl: but i have better things to do than babysitting my bot for a full 2 weeks tournament

struct: So write a bot that writes a bot

struct: :p

struct: But yeah

struct: doesnt seem fun

eulerscheZahl: i just have other things to do. like my normal job. and doing real life hobbies

Astrobytes: Football and catching mice?

eulerscheZahl: yes :D

eulerscheZahl: the mouse escaped again

Astrobytes: hahaha

eulerscheZahl: useless cat

Astrobytes: Some cats have that instinct, some don't. And when they don't - they *really* don't.

MONIGMA: exactly

eulerscheZahl: at least I managed to scrape replays from yare. So I can reproduce a certain frame offline without submitting a new bot and hoping that the same situations occurs

eulerscheZahl: my cat is just old (16 years)

eulerscheZahl: there were times when she brought 2 mice in a single night

Astrobytes: awww, she's an old lady!

eulerscheZahl: and released them in my room

MONIGMA: That cat has some energy

Astrobytes: Great when they do things like that.

eulerscheZahl: she liked those rainy nights when the mice had to leave their holes

MONIGMA: YEah until they kill the mouse then drop it

MONIGMA: ON YOUR LAP

Astrobytes: Birds flapping around the house, half dead rats squirming across the floor, mice with 3 legs hopping around

eulerscheZahl: once there was a mouse living in my shoe and I didn't notice at first

MONIGMA: YUK

eulerscheZahl: was full of cat food and mouse poop, had to throw it away

Astrobytes: lol, not a frequently worn shoe then :D

MONIGMA:

*retches*

**eulerscheZahl puts it on ebay, "barely used"

Astrobytes: :D

eve_va_hooves_the_king_of_wifes: im almost done with my class :)

jacek: no do the struct

struct: structs are bad

eve_va_hooves_the_king_of_wifes: did anyone have a good day so far?

Astrobytes: Gonna take your attention deficiency issues somewhere else eh?

eve_va_hooves_the_king_of_wifes: u talking to me?

Astrobytes: Yes.

eve_va_hooves_the_king_of_wifes: im already done with my class

eve_va_hooves_the_king_of_wifes: so im gonna try to code something

Astrobytes: Good. Stay off the chat.

Illedan: :(

struct: whats wrong Illedan

Illedan: Astro wants me to stay off chat

Illedan: :P

Astrobytes: lol

eve_va_hooves_the_king_of_wifes: i didnt do anything wrong......................yet

Illedan: and my 5 million last fb tries fails

eulerscheZahl: thank you astro

Astrobytes: np

Astrobytes: You were 3rd at some point Ille

Default avatar.png JacobTheCoder: hi

Illedan: Sure, I'm 100 % 3rd when I submit the best

struct: premeditation, should be banned

struct: :p

Illedan: Just autokick everyone below level 40

Default avatar.png JacobTheCoder: :(

struct: hi

Astrobytes: I better get my level up!

struct: Illedan I would not mind rank 3

struct: knowing who top 2 is

Astrobytes: He's going for the top

eulerscheZahl: can't find a monocle emoji

Default avatar.png JacobTheCoder: oof

struct: not worth the trouble

struct: trust me

Illedan: Give me a value between 1 and 0 for a test?

Wontonimo: :nerd: dual monocle

eulerscheZahl: pi/4

Astrobytes: 0.03145

struct: :spy_tone1:

Illedan: 0.78 that is euler

eulerscheZahl: only for small values of pi

struct: which algo do you use illedan?

Illedan: I simulate the game

Astrobytes: :grin:

struct: ...

eulerscheZahl: ̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤̤

Illedan: ^^

Illedan: Simultaneous GA

Astrobytes: ffs

Illedan: Same as sogeti

struct: I dont know what you used on sogeti

eulerscheZahl: read his forum post (is there any?)

Illedan: nope

eulerscheZahl: read it anyways

Illedan: Yeah, it's called void

struct: Why did I open forum...

Illedan: 16 wins in a row with 0.78. Lets go

struct: git copilot in coc discussion

eulerscheZahl: so that the "last seen" timer updates

eve_va_hooves_the_king_of_wifes: b

eve_va_hooves_the_king_of_wifes: oh it worked?

eulerscheZahl: much better than astro's value

Illedan: Yeah his value is bad

Astrobytes: shh

Astrobytes: Stop mocking my value.

Illedan: It is the distance between his furthest wizard and my goal for where I want to defend :P

Astrobytes: Well if you said that I'd have given a sensible number :P

Illedan: Which would be?

Astrobytes: 0.785

eve_va_hooves_the_king_of_wifes: duck

eulerscheZahl: mocking such a value, hmm :thinking:

eulerscheZahl: should I write and implement an interface for this case?

eulerscheZahl: and do I really have to mock it?

Astrobytes: Not that kind of mocking.

eulerscheZahl: :P

Illedan: Always mock

Astrobytes: :D

Illedan: Mock the cut too

Illedan: then mock the mock

Astrobytes: And everything becomes a mockery of itself?

Illedan: 3-0 vs reCurse. Lucky today. Soon crash and burn

Astrobytes: never say never

Illedan: 0.4 had 6-13 vs recu and 6-16 vs pb

eve_va_hooves_the_king_of_wifes: wha ya guys and girls coding?

Astrobytes: Programs.

Illedan: https://www.codingame.com/ide/puzzle/fantastic-bits

eve_va_hooves_the_king_of_wifes: okay, how long has everyone been coding?

Illedan: 30 min

Astrobytes: About 15 minutes

Default avatar.png Tenttsotne: among us candice sugondese obama ur mum deez nutz

eulerscheZahl: longer than you are old

Default avatar.png Tenttsotne: among us balls

eve_va_hooves_the_king_of_wifes: oh

eve_va_hooves_the_king_of_wifes: so 58 years?

Astrobytes: ty euler

eve_va_hooves_the_king_of_wifes: jk

mkkhell: i created C++

mkkhell: thank me later

eulerscheZahl: I invented christmas

Astrobytes: I am Santa Claus.

eulerscheZahl: and i got you from the streets, you were unemployed

Astrobytes: Eternally grateful

jacek: but you have to work on holidays

Illedan: I'm just a man, sitting in front of a computer, wanting his fb bot to reach first.

eve_va_hooves_the_king_of_wifes: anyone ever made a dating sim?

struct: yes

Astrobytes: Yes, it simulated an entire day ahead.

eve_va_hooves_the_king_of_wifes: oh,

eulerscheZahl: mine broke in September 1752 :(

Astrobytes: Give me my 11 days!

mkkhell: how can i learn advanced C++

mkkhell: ?

Astrobytes: Learn basic C++ then ++ it

jacek: is that true? https://i.redd.it/3l1d55j3k1m71.jpg

mkkhell: XD

eulerscheZahl: to C#?

eve_va_hooves_the_king_of_wifes: im gonna to my new class, bye good luck with ya codes

eve_va_hooves_the_king_of_wifes: i'll try to stay off the chat during class

Astrobytes: you're on thin ice, it's a ban next time

mkkhell: class or object?

Astrobytes: jacek: yes.

struct: This is the number you are looking for Illedan

struct: 0.84669248029520630246

struct: Thank me later

mkkhell: :radioactive:

eve_va_hooves_the_king_of_wifes: class mr. mkkhell

Illedan: 0.78 is too big

Illedan: I'll go down

eulerscheZahl: smaller pi

struct: pi/(e**2)

struct: 0.42516833158763632844

eulerscheZahl: i like the e part

Astrobytes: 0.27182818284

Illedan: I had 0.4 earlier, I'll try 0.55 now

jacek: e^pi - pi

Illedan: Too high

eulerscheZahl: looks familiar. is that the =20 thing from xkcd?

eulerscheZahl: https://xkcd.com/217/

Astrobytes: hahaha

jacek: eeyup

struct: from my personal experience with breakthrough

struct: its never worth to change values

struct: just add features to eval

jacek: yeah, most time the first guesses on hyperparameters are close to optimal

jacek: which sucks if you want to learn to automate tuning those

jacek: and youre done with breakthrough?

struct: No, I opened ludii breakthrough eval

struct: now I cant unsee it

Astrobytes: :D

jacek: we lost him

jacek: just like we lost reBless to chess

Astrobytes: Hey, reBless has other duties too these days

jacek: he also does shogi?

Astrobytes: :smirk:

eulerscheZahl: https://www.youtube.com/watch?v=5hvRrhhzpZc

Astrobytes: aka Hell on a Chessboard

jacek: kriegspiel?

Astrobytes: wouldn't that be kriegsspiel?

Astrobytes: Mein Deutsch ist nicht so gut.

jacek: :scream:

Astrobytes: But I remember such useful things as die Apotheke, die Bibliothek and other exceptionally useful things

jacek: hande hoch!

eulerscheZahl: i'm with astro on the Fugen-s

eulerscheZahl: and it's Hände, not hande. You would be a bad robber

Astrobytes: yay, I remembered something correctly from a long time ago

jacek: i knew. i dont have ä in my keyboard

eulerscheZahl: i speak astro's language better than he speaks mine. But jacek is better at German than I am at Polish

eulerscheZahl: kurwa

Astrobytes: Always preferred kurwa mać myself

**Astrobytes kicks himself

jacek: oO

jacek: now learn the pierdolić https://i.redd.it/zw28vjrtkbc41.png

Astrobytes: That looks fun

darkhorse64: struct: ludii breakthrough eval ? Is there a paper or a website that I can look at ?

struct: https://github.com/Ludeme/Ludii/blob/7b1ebd3817486b21cad636daa762a29b86f05e30/Common/res/def_ai/Breakthrough_ai.def

Astrobytes: Caralho! Now look what you've done! :P

eve_va_hooves_the_king_of_wifes: im done with class and just ate, can anyone help me with coders strike back?

struct: might be a bit hard to understand

**Astrobytes runs off to modify his BT eval

eve_va_hooves_the_king_of_wifes: how hard?

struct: but if you search cornerProximity on the search bar of github

struct: or the keywords that you want

eulerscheZahl: where do these constants come from? they don't look random

jacek: hand crafted :v

struct: it should find the java class

darkhorse64: thanks. Even more code to browse

MONIGMA: Im still on Coders Strike back too

MONIGMA: EVE, whats your rank

struct: csb is only the begining

eve_va_hooves_the_king_of_wifes: <->

eve_va_hooves_the_king_of_wifes: let me check

eve_va_hooves_the_king_of_wifes: 26,459th rookie

eve_va_hooves_the_king_of_wifes: and im level 4

Astrobytes: rank IN CSB

jacek: i wonder if i could extract simple piece-square tables from the NN for breakthrough

MONIGMA: Im in CSB 5298th/54694

jacek: wood?

Astrobytes: Didn't you try that already jacek?

MONIGMA: 2

Astrobytes: piece-square tables I mean

jacek: i dont remember. long ago a tried texel tuning for psqt

Astrobytes: that might have been it then

jacek: yay im 3rd https://www.littlegolem.net/jsp/info/player_list.jsp?gtvar=brkthr_DEFAULT

eve_va_hooves_the_king_of_wifes: soo? is there any code programs you think i can try for a rookie like myself

Astrobytes: Nice work jacek

struct: games that dont have a result yet are still ongoing right?

struct: in little golem

jacek: yes

struct: one of them seems won already

jacek: i have 3 ongoing games. 1 is proven win

struct: at least is easy to see

struct: yeah

jacek: other one is like 80%

Astrobytes: Just wait, 5 more years and you'll be first!

struct: do top 2 players every challenge you?

eulerscheZahl: that website sends a full request every time I step back and forth, not just client side updating :o

jacek: i participate in some 'infinite' tournament

jacek: every month or so a bunch of new games are played

struct: Is it the same bot since the start?

jacek: there was 1 major rewrite

eve_va_hooves_the_king_of_wifes: can i ask something about codeing things?

struct: sure

jacek: i used entirely new learning framework i use for CG now

eve_va_hooves_the_king_of_wifes: what was the hardest thing you ever coded?

Astrobytes: A diamond simulator.

eve_va_hooves_the_king_of_wifes: oh, whats that?

jacek: graph traversing algorithm that generates possible moves for paper soccer

jacek: that was hard

jacek: ~

Astrobytes: :drum:

eve_va_hooves_the_king_of_wifes: the hardest i ever coded was a dating sim

Astrobytes: Getting a girl/boyfriend might be easier and a little less creepy.

eve_va_hooves_the_king_of_wifes: ehhhhhh.........true enough

jacek: getting a waifu is hard

eve_va_hooves_the_king_of_wifes: most of the people i meet........i made them hate me

Astrobytes: I cannot imagine why that might be.

jacek: i wonder why :thinking:

eve_va_hooves_the_king_of_wifes: cuz i made them

eve_va_hooves_the_king_of_wifes: i love making people hate me sometimes

Astrobytes: I recommend you leave the chat and re-evaluate your motives and goals in life.

eve_va_hooves_the_king_of_wifes: already did that

**Astrobytes shakes fist at clouds

Default avatar.png mr.nomad: heh

Default avatar.png Bobbelo: Hey guys, is it not possible to scroll through the previous messages in this chat?

eulerscheZahl: not directly

eulerscheZahl: there is https://cg.spdns.eu/wiki/Special:PrefixIndex?prefix=World%2F&namespace=3000

Default avatar.png mr.nomad: i blame myself for that

eulerscheZahl: will update chat logs once a day, next time in about 10h

eulerscheZahl: except for august 28th+29th, dbdr stole them

Default avatar.png mr.nomad: hey adman

Default avatar.png KennaR12: timer

Default avatar.png mr.nomad: i got banned

Default avatar.png Bobbelo: @eulerscheZahl When was the last time you updated the chat log?

Default avatar.png Bobbelo: Wait, nvm I can now scroll through the chat. I couldn't earlier for some reason

Default avatar.png Bobbelo: Strange

eulerscheZahl: i don't update the chat log, that's dbdr's project. and it was 14h ago

eulerscheZahl: https://cg.spdns.eu/wiki/Special:RecentChanges?limit=50&days=7&enhanced=1&urlversion=2

eulerscheZahl: Fr more active than World these days

Astrobytes: Is there some smoothing that jrke can do on that cube that wouldn't slow things down too much? The aliasing is making me itchy.

Astrobytes: It's very nice though, he's done a damn good job

eulerscheZahl: it took me 1 or 2 days to get the rolling animation working as expected for dice duel. these things really mess with your brain

eulerscheZahl: and he combined pixi + three.js

eulerscheZahl: while I just deleted pixi entirely

Astrobytes: Yeah rotational stuff gets a little unwieldy in 3D at times.

Astrobytes: It's really rather good though, I am impressed.

eulerscheZahl: the nasty part is that you have to rotate around the internal axis of a die while still looking from an external perspective

Default avatar.png Bobbelo: @eulerscheZahl Thanks for letting me know. Also I'm fairly new at programming, and I thought I had at least a foot in the basics until I started doing the simple exercises you guys provide XD. It's been quite reassuring when I finally get past them though. I'm really enjoying the feeling of finally finishing one of them. (Not being stuck on them though XD)

eulerscheZahl: i'm impressed too. I wasn't sure if he's going to make it going by his questions on discord

eulerscheZahl: how did that not turn into a pastebin?

Astrobytes: All typed in one line

eulerscheZahl: there's a char limit too

Astrobytes: char limit not exceeded clearly

eulerscheZahl: congrats on making progress Bobbelo

eulerscheZahl: the first steps are always the hardest

eulerscheZahl: you will still scratch your head at other things. but it gets easier when you understand the basics

Astrobytes: Yeah well done Bobbelo. Keep working away at them, the more you learn the... yes, what euler said :P

eulerscheZahl: bed time, see you

Astrobytes: night man, take care

jacek: :older_man:

Wontonimo: gn

Astrobytes: I'm out as well actually, but I'm gonna practice my guitar now that my hand seems able again

Astrobytes: See ya's later or tomorrow

jacek: hand able again :smirk:

ja_fica: jolindien?

ja_fica: nn or opening book?

ja_fica: in C4

AllYourTrees: :eyes:

struct: nn is most likely

jolindien: hi

jolindien: nn

Default avatar.png Tenttsotne: deez nutz

ja_fica: top 5 corresponds to offline training

ja_fica: impressive being in C#

struct: its a wrapper

struct: it uses c++

Okido: Ignore Browser Shortcuts (Ctrl+C): http://chat.codingame.com/pastebin/94737506-c7a7-4380-b4b5-b0b3df13a355

struct: darkhorse64

struct: https://ludii.games/downloads/LudiiLanguageReference.pdf

struct: 19.4

ja_fica: C# is easier to implement?

darkhorse64: reading it

struct: ja_fica im not sure why they use C#

jolindien: c# because an encoder was available

struct: But the ai runs on c++ right?

jolindien: yes

jolindien: https://github.com/marchete/CGZero/blob/master/src/ENCODER16k.cs

jolindien: ja_fica, for you it's MCTS ?

ja_fica: with opening book

jolindien: nice

ja_fica: makes a big differenece

jolindien: no evaluation function ?

ja_fica: I wouldnt call it an evaluation function but I choose to simulate first the moves that result in higher winning positions

ja_fica: I do this only in expansion

jolindien: higher winning posiions ?

darkhorse64: still MCTS with full rollouts at #7

struct: maybe I need to resubmit

struct: my bot fell down a lot

struct: :(

jolindien: you certainly have performant sims

ja_fica: yes, you bot was in #2 if not rank #1 back in the days

struct: yes I have around 3M sims/sec

struct: rolouts*

struct: not sims

ja_fica: I think struct and darkhorse have the best bots without offline training

darkhorse64: did you get what is Pawn1, Pawn2 in Ludii ? 2M rollouts for me. I feel like a dinosaur

jolindien: what is the idea to find quickly winning moves (killer moves)?

struct: jolindien so you dont make a move that make opp win

jolindien: i mean with bitboards

struct: darkhorse64 your pieces and opp pieces

struct: I think

darkhorse64: make sense

darkhorse64: *makes*

ja_fica: I forsee 4 positions at the same time using AVX

struct: jolindien you want to know how to do it?

jolindien: yes

ja_fica: without AVX I have only arround 45% of rollouts

darkhorse64: The idea is to find winning moves for the opponent to avoid them in rollouts

struct: http://blog.gamesolver.org/solving-connect-four/09-anticipate-losing-moves/

struct: My way is based on that

ja_fica: mine 2 with another step ahead

jolindien: my issue is not about algo

jolindien: ok

ja_fica: You use alpha0 pipeline right?

struct: whats is your issue?

struct: I can try to explain.

jolindien: ja_fica, I have re-written a sort of alpha0

jolindien: thx struct, I think it's compute_winning_position() function

ja_fica: struct is climbing the ladder like a boss xD

struct: robo had too many battles vs me

struct: it was like 50+ loses

struct: My bot cant handle him at all

struct: With my bitboard I had to use both shifts << and shift >> to get winning position

struct: if I only use << it would make bits go out of range(?)

ja_fica: I had to use MASK, rigth and left

struct: yeah I also use masks

jolindien: because of weird size

ja_fica: jolindien have you tried to apply the same algo in UTTT?

jolindien: not yet

jolindien: I heard it's really hard

AllYourTrees: i found C4 plenty hard lol

struct: im still amazed that royale got 1st in yavalath

jolindien: for me it was easier than oware

struct: vs msmit book

struct: and bot* his bot is strong

jolindien: royale uses mcts ?

struct: im not sure

struct: I just know its NN

jolindien: he is high in many board games

AllYourTrees: hes using nn in c4

jolindien: ahh ok

ja_fica: my opening book only have 600 positions and it is enought

ja_fica: I get to 15 plays book often, you can see it by my output

struct: msmits book on yavalath is different

struct: its a trap based game

struct: so its a bit different from c4

struct: maybe ill make a bot for it and submit a bos

struct: so it can get potw

Illedan: jolindien, did you get your Sogeti price?

jolindien: no

jolindien: Pb neither

jolindien: (Pb4_)

Illedan: :+1:

Illedan: Mine was still shipping

jolindien: don't have news

jolindien: at all

ja_fica: Why most top programmers in CG are from France?

Illedan: CG is a france based company

Illedan: Gotta start somewhere

jolindien: french are smart

Illedan: ^^

ja_fica: it seems that way

jolindien: and arrogant

Remi_avec_un_i: hey ! french people can read that ! ^^

ja_fica: The rate of French/Rest of the world is not even near Male/Female

ja_fica: I guess its because of preferences

ja_fica: BTW does anyone else found out that having a larger constant in UCT on MCTS is better in case of a better processor?

ja_fica: winrate + CONSTANT * exploration

jolindien: makes sense

ja_fica: at night I submit my bot with 1.5, at day I submit at 1.4 because the server are busier, I guess I could test the processor speed on the precomputation in pick the constant from there

jolindien: if you can spend more time in exploration

jolindien: *if you have more time ...

struct: let me see which NNs still have the problem of playing poorly vs bad bots

struct: robo fixed it

struct: for his

jolindien: I have

ja_fica: royale loses games at 35 plays

struct: yes you have that problem jolindien

jolindien: what is the solution ?

struct: I never asked robo

jolindien: more exploration during training or inline ?

ja_fica: In the offline training play it against regular MTCS as well instead of just nn vs nn

jolindien: I have to work on my UCT formula

jolindien: I don't like PUCT

jolindien: ja_fica, good idea

ja_fica: you have the transition probabilities as well?

jolindien: yes

ja_fica: PUCT may fives some advantages as you spare time using the last layer vector in the NN to get the transition probabilities

ja_fica: *may give

struct: https://www.codingame.com/replay/579355924

struct: this is my bot with 1000. exploration factor

struct: so its random

struct: but still has the tree

jolindien: problem with PUCT is that it gives too much priority to probabilities

jolindien: with small nn, my probas are not so reliables

ja_fica: yes you can add do a (x+p)/(1+x) to reduce the factor

jolindien: oh bad loose

struct: this one is worse

struct: https://www.codingame.com/replay/579356006

AllYourTrees: i think its just that the number of tree expansions on CG is so high that with lower puct constants, PUCt converges really quickly

jolindien: yeah I loose some games in 9 turn :)

ja_fica: basicly, the training fase you cannot just play against your better nn

jolindien: with an eval .98 ...

ja_fica: it will be blind to other bad plays

jolindien: it is the alpha0 algo

jolindien: but here again it is designed for really performant nn

AllYourTrees: its annoying how important the parameters for alphazero are

struct: I cant remember if robo uses 16 bits or 8

struct: I remember that he increased performance a lot

struct: I think it was from 32 bits to 16 bits

Default avatar.png JacobTheCoder: hello

struct: But not the weights

struct: I dont know the term for it

Default avatar.png JacobTheCoder: is it possible to shit

Default avatar.png JacobTheCoder: WHAT

AllYourTrees: quantization

struct: Yeah I think that was it

ja_fica: he uses 8 bits

ja_fica: but floating 8 bits?

ja_fica: or integer 8 bits...

struct: well he uses avx I guess

struct: So it must be int8

ja_fica: has anyone though of using the neuralnetwork to just the UCT constant in each node?

ja_fica: to ajust*

ja_fica: it can only be trained using ARS but it seems worth it

jolindien: I saw a paper on that

jolindien: ARS ?

ja_fica: augmented random search

ja_fica: it works better then drl for many tasks

ja_fica: but like days difference better

ja_fica: in openAI gym there is an environment, bipedalWalkerV2 where ARS is around 10x faster to learn then the usual deep reinforcement learning algorithms

jolindien: would you have a ref ?

Default avatar.png JacobTheCoder: i am super new to coding, dont know a single bit any suggestions on where i sohuld go?

Default avatar.png JacobTheCoder: should*

ja_fica: I had a project to test it

ja_fica: JacobTheCoder, start with the puzzles in you most comforting programming language

ja_fica: I also developed a even faster version GRS - genetic random search

ja_fica: https://paste.ofcode.org/c4ZBYb28YKvztFsCJwm7ri

jolindien: thx !

_Royale: jolindien: MCTS with transpositions, NN with value/policy outputs (on Connect4, Othello, Yavalath and Oware)

jolindien: hi _Royale !

jolindien: transpositions ?

jolindien: do you mean for cache ?

jolindien: (for nn cache) ?

Default avatar.png Chighsmith: how did you all learn to coode

Default avatar.png Chighsmith: code

struct: by doing

Default avatar.png Chighsmith: here? or just working on projects?

struct: I learned quite a bit here

Default avatar.png Chighsmith: i just seem a bit lost im a cs student and Im doing well in the classes it just seems hard to apply it

struct: Yeah, its not very beginner friendly

Default avatar.png Chighsmith: I guess you feel bad at coding for a long time until one day you realize you don't lol

struct: How long have you been a cs student?

Default avatar.png Chighsmith: about a year so im still intro but I dabbled in it in my last degree which brought me over to cs

struct: With 1 year I think you should be able to solve some puzzles

Default avatar.png Chighsmith: Did you ever have a mentor or anybody to help you learn?

struct: https://www.codingame.com/training/easy/the-descent

Default avatar.png Chighsmith: I'll give that one a go

struct: no, but chat helps sometimes

_Royale: jolindien: transpositions for the nodes so I can reuse already explored sub-trees

Default avatar.png Chighsmith: ahh gotcha

jolindien: are you inspired by alpha0 too ?

_Royale: yes I did NN before but only for the value (like jacek)

struct: is your breakthrough bot NN?

_Royale: reCurse PM on last contest and Marchete motivated me to try harder with policy :-)

Marchete: :thumbsup:

jolindien: gg

_Royale: struct: on breakthrough I did logistic regression

struct: thanks

_Royale: and no policy

jolindien: Marchete did you see alpha zero pseudo code ?

jolindien: (pseudocode.py in additional material)

jolindien: it provides some parameters which are not in the paper

_Royale: yeah more parameters to tune \o/

jolindien: no policy ... so logistic regression on value ?

jolindien: -1 / 1

jolindien: I thought policy was more important with a large branching factor ...

Medoo: Good night everyone

Default avatar.png C26_1: Wait

Default avatar.png C26_1: In Vietnam, this should be day not night so.............

Medoo: Well, its almost 4 am in here. Have a great day for you.

Default avatar.png C26_1: ok

Default avatar.png C26_1: so 3 hours late

Default avatar.png C26_1: Can I post a challenge in here

Default avatar.png C26_1: Statement: John is a base analysis, he needs to make a program where he could take a number in his own notation and translate it into base 10

Default avatar.png C26_1: Input description:

Default avatar.png C26_1: <<Line 1:>> A variable "N" and base "B" with space seperated

Default avatar.png C26_1: <<Line 2:>> An array contains N numbers in them

Default avatar.png C26_1: space seperated also

Default avatar.png C26_1: Output description: A number in base 10

Default avatar.png BACONMANXDGODXD: hu

Default avatar.png C26_1: Example:


Default avatar.png BACONMANXDGODXD: huh

Default avatar.png C26_1: Input: 3 24 12 13 14

Default avatar.png C26_1: Output: 7238

Default avatar.png JacobTheCoder: hi

Default avatar.png C26_1: hi

Default avatar.png waffles: C26_1 is that a question?

Default avatar.png waffles: nevermind

Justin-Truong: How

VeilTape: str.maketrans is a useful trick

VeilTape: for shortest mode python

Default avatar.png Jasher_Yen: hi

holyterror: hello

Default avatar.png pythonforfun_2: VeilTape i was literally just talking about maketrans like 2 seconds ago
