Default avatar.png Switch64: How do you put out a baby from a mixer ? With a straw *

PeyoakaJesus: my little died in a mixer it's not funny

PeyoakaJesus: brother

Default avatar.png Jean-Paul: :cold_sweat:

MadKnight: what is going on here

Default avatar.png Switch64: How do you call a dwarf that works at the THE POST : A dwarfposter

MadKnight: calm down Switch64

Default avatar.png Switch64: Sorry sorry we are between friends having fun in class

Default avatar.png Switch64: it's pretty hard to be honest

MadKnight: u can just go to a private class

Default avatar.png Switch64: (that was she said)

MadKnight: chat

MadKnight: class chat

Default avatar.png ubaire: What does the left eye says to the right eye ? Something spells here

MadKnight: #switchchat

Default avatar.png ubaire: Between us

Default avatar.png Jean-Paul: MadKnight is the Impostor

MadKnight: everyone click #switchchat

Default avatar.png ubaire: THANK YOU

Default avatar.png Jean-Paul: vote MadKnight

Default avatar.png Switch64: ty you are the best

PeyoakaJesus: GOD BLEES YOU

Default avatar.png Switch64: better than BlaiseEbuth

PeyoakaJesus: BEST MODO EVER

Default avatar.png Switch64: i love you mad knight ty

Default avatar.png ubaire: us

Default avatar.png ubaire: you are a better modo than blaiseebuth

Default avatar.png Jean-Paul: ty

JSboss: ya he is a bit of a tyrant

BlaiseEbuth: Something to say ?

MadKnight: BlaiseTyranth

CodingCommander03: in csb will the score reset every time in test in arena ?

MadKnight: right

MadKnight: when u submit it starts all over again

CodingCommander03: okay thanks

derjack: who cares about csb

MadKnight: yea exactly

MadKnight: Automaton2000 let's play some graph games

Automaton2000: dont want to know that

Default avatar.png Jean-Paul: MadKnight>BlaiseEbuth

MadKnight: dude u won't hurt his feelings with that

derjack: graph games? like hypersonic?

MadKnight: no that's a grid

BlaiseEbuth: A grid is peculiar graph

BlaiseEbuth: +a

MadKnight: it's about optimizing grids to the point where it's just a int128

MadKnight: and all that grid-related stuff

MadKnight: BlaiseEbuth are u not upset about our old fight anymore?

BlaiseEbuth: I will not ignore you on public chat...

Default avatar.png ubaire: Be cool guys

MadKnight: well good enough

Default avatar.png ubaire: Why did Mr. Hass refuse to move to France? The French are famous for not pronouncing the letter ‘H’.


MadKnight: no passive aggression Automaton2000

Automaton2000: is it possible to get that with a simple ga

MadKnight: ubaire #switchchat

Default avatar.png ubaire: #switchchat

VizGhar: Which puzzle/bot contest you recommend for GA?

MadKnight: single player actually

BlaiseEbuth: code vs zombie

MadKnight: and where the late moves don't depend on the early moves

MadKnight: because y'know

MadKnight: in most games if u change early moves

MadKnight: all the future moves just break

MadKnight: well CvZ not perfect but pretty good

derjack: :soccer:

Uljahn: Marslander ep.2/3 could be a good choice with simulation being easy enough, also there are some blog posts about implementing GA in marslander

Default avatar.png Jean-Paul: x

MadKnight: now that's an actually good suggestion

MadKnight: Jean-Paul i hope u are not trying to get banned in here too? after #fr

Default avatar.png Jean-Paul: nop

MadKnight: okay cool

MadKnight: wow

MadKnight: RuthlessEbuth

MadKnight: RuthlessTyranth

BlaiseEbuth: He insult me on the chan you created for them. So he can stay there

derjack: MadBlaise

derjack: the ultimate insult

AntiSquid: oh daporan actually made it to first, it didn't look good last i checked and thought pb had a strong NN, neuman 2nd :o

Default avatar.png Lucie-Fer: :thumbsdown_tone2:

BlaiseEbuth: Problem ubaire ?

Default avatar.png Lucie-Fer: My name is LUCYFER

MadKnight: dude #switchchat

BlaiseEbuth: Cool

Default avatar.png Lucie-Fer: You're Belzebuth I'm Lucifer, we're bros

MadKnight: i think he's gonna ban u now

BlaiseEbuth: In fact my alt account was named Lucie Faire

Default avatar.png Lucie-Fer: Whyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

VizGhar: I already have simulator for mars-lander implemented 100% correctly... I'll try to use it there

Default avatar.png Lucie-Fer: Can smbdy help me on Power of Thor pls

MadKnight: oh that's good VizGhar

Default avatar.png Lucie-Fer: I'm kinda stuck here

MadKnight: can u explain the problem

MadKnight: ?

VizGhar: try hint on the left Lucie-Fer or ask what exactly you need

Default avatar.png Lucie-Fer: Got it !!

Default avatar.png Lucie-Fer: Thank you all for your kindness

Default avatar.png Lucie-Fer: God bless you guys

MadKnight: no problem

MadKnight: Automaton2000 where's my CodinPoints for helping

Automaton2000: i don't know how to install it

Westicles: Happy Ambedkar Jayanti Day

MadKnight: what is even that day?

AntiSquid: ya, not even google celebrates it

jrke: indian celebrates it i mean just by wishing

jrke: he was the father of our constitution

AntiSquid: are you Indian or partially Indian Westicles ?

AntiSquid: or is your wife indian?

Westicles: No, robinhood was telling me about it

Westicles: I guess they all have the day off

Westicles: Everything I know about India is from the movie Sholay

jrke: :smiley:

VizGhar: is robinhood some kind of meme? I don't recall seeing anybody with this name here

VizGhar: but he is mentioned quite often

jrke: robinhood is codingamer remains active in indian chat as far as i know

AntiSquid: VizGhar, he made multiple accounts with similar name, got banned multiple times, keeps create new accounts

VizGhar: :D how can you get banned here ffs? And why would you come back... people are strange

Westicles: I got banned once, almost twice to be honest

jrke: i haven't banned yet

jrke: lucky :)

BlaiseEbuth: Strange Westicles... :thinking:

AntiSquid: multiple reasons, constant spam, swear words out of the blue VizGhar, repetitive messages that are completely pointless for example ... but he was also trolling a bit more than that

AntiSquid: i don't know what others ban for, might include being politically incorrect i guess, nothing i deal with though

Default avatar.png Mil27Coder: hi

VizGhar: :thumbsup:

jrke: i still remember i was one of the spammer during spring challenge 2020 cause i was new to coding and codingame

AntiSquid: depends what you see as spam

derjack: i never got banned o.O

AntiSquid: never too late

BlaiseEbuth: I can fix that for you.

Default avatar.png Mil27Coder: can someone help learn js

AntiSquid: put more effort in it derjack, especially if it's an alt account which is not allowed to begin with

Default avatar.png ErrorRazor: Mil27Coder here you go: https://duckduckgo.com/?t=ffab&q=javascript+tutorial&ia=web

AntiSquid: jrke i see regulars spam too, it's more about not being obnoxious when you do it, but there are also double standards i've seen, school kids who join as a group occasionally got kicked / banned for the same thing regulars did without side-effects ...

VizGhar: I have one alt account, just for showing my students first 2-3 puzzles :P

AntiSquid: there's the argument school kids are less predictable

jrke: ohkay

AntiSquid: what were your spam messages anyway jrke ?

AntiSquid: asking questions / help isn't spam @_@

jrke: like keep asking every moment for advices

jrke: i was asking for help but very frequent messages

AntiSquid: isn't that normal if you're new?

jrke: hmmm....

AntiSquid: if it's "can i ask a question" then ... oof

AntiSquid: actually people do that a lot in real life! :D

AntiSquid: even when it's clear i am there to help them

Default avatar.png ErrorRazor: Interesting potw

Default avatar.png Kokahina: Hello

Default avatar.png ErrorRazor: Hi

PhamTuanMinh1: Hi

Bari: Hello

AntiSquid: hi

derjack:

Matrix007: hello guys...

Matrix007: i have a doubt

Matrix007: in Horse -racing duals

Matrix007: two test cases seems to satisfy it but the third test case shows somehting totally different

Matrix007: http://chat.codingame.com/pastebin/5d71b5f9-0e75-4a7c-acd6-93741aa6d58b

Matrix007: idk where i am making the mistake:upside_down:

Default avatar.png ErrorRazor: for (int i = 0; i < N; i++) {

      diff[i]=inp[i+1]-inp[i];

^shouldn't the program cash when you try to access inp[N]?

Default avatar.png ErrorRazor: crash*

Default avatar.png ErrorRazor: unless inp[N] points to diff[0] since they're declared together, idk how that works

Matrix007: oh yah...it must crash right??....but how does it work??

Matrix007: i dont know my code:no_mouth:

Default avatar.png ErrorRazor: Try printing inp[N] and see what's in there

Uljahn: ye, it works with i < N -1 and diff[N-1]

Default avatar.png ErrorRazor: The sorting can be simplified btw, just do sort(inp, inp + N)

Matrix007: it prints the garbage value .....thats what messed me up in the last case

Matrix007: i just saw the hint it says to simplify the number of comparisons...

Matrix007: as it clearly defines that my logic will not work in the long run

Uljahn: the second sorting could be replaced with finding minimum i guess

Default avatar.png ErrorRazor: I got 100% with python, so you should be good

Matrix007: i will try:thumbsup:

Default avatar.png ErrorRazor: I never realized there was a hints button lmao

Uljahn: that button is quite rare, only 4 or 5 puzzles have it

Default avatar.png ErrorRazor: Ah okay

Default avatar.png Hamza_Abdelal: hiiiiiiiiiiii

AntiSquid: how many alts are you going to make robin_hood ? kinda boring really

derjack: why would anyone create an alt here

BlaiseEbuth: For glory !

AntiSquid: to replay lower leagues

IshaanJ: hi

Rudrigo: hello friends

Default avatar.png ensamblador: hi

Butanium: hi

Default avatar.png ThatGuyRadnii: People smurf CodinGame?

struct: nah

ZarthaxX: struct does

struct: yes

Default avatar.png Auto2552: BSOD

BlaiseEbuth: HCF

struct: Finally found how to cast binary values of __m256 to __m256i

ZarthaxX: how so :P

ZarthaxX: doesnt seem hard

struct: Is there an instruction for it?

ZarthaxX: i mean they are the same registers

ZarthaxX: low level wise

Default avatar.png heloche: howdy

pb4: struct : what does that mean ?

pb4: Are you speaking about the equivalent of a reinterpret_cast<>() ?

struct: 10.0f = 01000001001000000000000000000000

struct: binary

struct: which equals 1092616192

pb4: so that's a reinterpret cast

pb4: What's your solution ?

struct: _mm256_cvtepi32_ps(*(__m256i*)(&x))

struct: x being a __m256

pb4: wow

pb4: I think I struggled on this question some time ago

pb4: But I don't remember having that many steps in the solution

pb4: But it seems I don't use it anymore in my latest engine, I don't know where I'd find what I used

struct: So there should be a shorter way?

pb4: I might be mistaken, maybe I was using m128 at the time

struct: It converts back to __m256 though

struct: the binary equivalent is the just the *(__m256i*)(&x)

struct: But there might be a better way, im not really good with avx

pb4: I'm looking through my old engines

pb4: They were _m128

pb4: I have this somewhere

pb4: #define v4i_to_v4f(a) (_mm_castsi128_ps(a))

  1. define v4f_to_v4i(a) (_mm_castps_si128(a))
  2. define int4_to_v4i(a) (*(v4i *)&(a))

pb4: I beilieve all those are reinterpret_cast<>()

struct: you are right

struct: _mm256_castps_si256

struct: does the same :/

struct: Dont know how I missed it

struct: Thanks

pb4: I'm finding this : __m256 _mm256_castsi256_ps (__m256i a)

pb4: Yeah, other way around

struct: Thanks for the help

pb4: It's easy to miss, the search engine on the intel intrinsics guide isn't the best...

pb4: Do you use other resources when looking for intrinsics ?

struct: Only this https://github.com/vectorclass/version2

struct: and intel intrinsics site

ZarthaxX: wow

ZarthaxX: did you see the _mm256_castps_si256 description struct?

ZarthaxX: it's just a compiled thing as at low level its all the same hehe

pb4: Thanks !

pb4: Yeah that's the reinterpret_cast ZarthaxX :)

pb4: very different from static_cast

ZarthaxX: but that one is not for intrinsics only right?


ZarthaxX: any type of data

pb4: reinterpret_cast and static_cast are for scalar values

ZarthaxX: ah okey

ZarthaxX: never used any, thanks for that, will look it up :o

pb4: static_cast is the basic cast

struct: Now I will try again what I talked with you the last time ZarthaxX, I never managed to do it.

struct: Get index of highest value of __m256

ZarthaxX: i have code for that

ZarthaxX: :P

ZarthaxX: but not for yout type of data

ZarthaxX: talk with me on pm if you want

pb4: So it's the argmax you need ?

ZarthaxX: yes he needs that

struct: yes

pb4: Curious about your solution :)

ZarthaxX: get index of max value in a simd reg

ZarthaxX: i have the power of 2 solution here

pb4: uh ?

struct: I think he means he has 2 solutions for it

ZarthaxX: mmm

ZarthaxX: http://chat.codingame.com/pastebin/f6a3c53f-ac65-48df-8dca-af307b84aee2

ZarthaxX: that one is for 256

ZarthaxX: short values

ZarthaxX: did you mean that struct?

ZarthaxX: SIMDreg is just a struct

ZarthaxX: i can explain it, but basically it's just taking the max between pairs, then between pairs of pairs bla bla

ZarthaxX: that's why i said the power of 2 solution

ZarthaxX: union SIMDreg{

       __m128i x;
       __m256i y;
   };

ZarthaxX: struct want some explanation?

Default avatar.png ThatGuyRadnii: Is the CodinGame Get A Job feature actually useful?

struct: ZarthaxX I think you explained it to me before

struct: on discord

Smelty: hi

ZarthaxX: and you didnt get it

ZarthaxX: :(

pb4: Didn't know that solution ZarthaxX

ZarthaxX: i need to voice chat with you lol

pb4: I have a different one

ZarthaxX: yours is simpler i guess

pb4: Nah

ZarthaxX: you are a master

ZarthaxX: oh

ZarthaxX: but did you understand mine? its hard as there isnt a context

ZarthaxX: missing some variables declarations

pb4: Same idea to permute the solutions to have only the maximum value at the end

ZarthaxX: the idea is simple

ZarthaxX: ah okey

struct: for(int i = 0; i < 8; ++i)

struct: easy

ZarthaxX: :rofl:

pb4: but I take a mask each time

ZarthaxX: ah okey

pb4: I apply the mask twice

pb4: once to the values

pb4: once to a vector of 0, 1, 2, 3, 4....

ZarthaxX: isnt it more expensive? :thinking:

ZarthaxX: my solution was explained here

pb4: and in the end, my vector of 0, 1, 2, 3, ... contains 3, 3, 3, 3, 3, 3... if 3 was the argmax

ZarthaxX: https://media.discordapp.net/attachments/634216430883045402/809574333390913546/unknown.png?width=733&height=454

ZarthaxX: an example of what is happenning

ZarthaxX: ah pb4 ok

ZarthaxX: i did that broadcast for finding the index later

ZarthaxX: do you apply a mask to the vector to put the intermediate max values pb4 ?

ZarthaxX: :thinking:

Marchete: why AVX?

ZarthaxX: why not

ZarthaxX: i dont really get that question

Smelty: hi

ZarthaxX: hello

Marchete: what kind of code to use AVX?

ZarthaxX: ask struct

Marchete: I did, see "why AVX?"

Default avatar.png groksula: i read that declarative programming is good

Default avatar.png groksula: at least in js

Default avatar.png groksula: map instead of loops

Default avatar.png groksula: but its way slower to run, by factor of x100s sometimes

Default avatar.png groksula: why is it better?

ZarthaxX: Marchete but tag him lol

struct: if i have a __m256 should I use avx to find max value?

struct: or max value index

struct: shouldnt*

ZarthaxX: yep

ZarthaxX: it's ok

Marchete: max value inside it?

ZarthaxX: i think he is asking why do you have that m256

ZarthaxX: :P

ZarthaxX: Marchete yup

struct: yes

Marchete: what are you doing with AVX? just curious

struct: Im going back to csb

struct: to finish it

Marchete: aaargh

**Marchete runs away

struct: :(

Marchete: jk good luck

Default avatar.png dominik-pm: man forgot the return haha

ZarthaxX: puto Marchete

Marchete: I think NN and these approaches beat the raw power of sim with AVX

struct: Yeah

struct: AVX stands no chance vs NNs

struct: at least the tops ones

struct: I mostly do this for fun

ZarthaxX: leave the optim guy alone

ZarthaxX: :C

Marchete: ok, if it's for fun and learning it's good

ZarthaxX: and bullying you sir

ZarthaxX: struct you doing it ? :thinking:

struct: Im going to try it yes

ZarthaxX: aight

ZarthaxX: tell me if you need smth

struct: thanks

Marchete: struct

Marchete: do you want code?

Marchete: I maybe have some oold ancient code

Marchete: it had GA, go figure...

struct: Well, it would save my brain

ZarthaxX: i threw him code too :(

Marchete: not a working bot

Marchete: just the sim

ZarthaxX: ah for csb

ZarthaxX: meh

struct: ah no

struct: I guess I could check

struct: I like to read others code

struct: I always learn something

Marchete: "I like to read others code" I doubt in that case

Marchete: hmm

Marchete: https://gist.github.com/marchete/1db9319be7a134560e0c87e41affbb7d

Marchete: enjoy the pain

Marchete: play against yourself

Marchete: last line will give you the sim accuracy

Marchete: Fails/Over/Turn:0/0/413

struct: I read your pcr code

struct: wasnt that bad :p

Marchete: means no failed turns

Marchete: ahh, it's true

struct: Thanks I will check it out

Marchete: #define SIMLOG is the switch to enable the simulation test

Marchete: anyways nothing else was completed

Marchete: but sim seemed OK

struct: Same situation for me on my csb code

struct: I finished sim but never finished ai

Marchete: for ideas about AVX, better go to https://github.com/vectorclass/version2/blob/master/vectorf256.h

Marchete: That's Agner's Fog vector class

Marchete: a very good one

Marchete: with many tricks

Marchete: STI v8 max(P8fab){return _mm256_max_ps(a,b);}

Marchete: you don't need tricks for max float

pb4: Marchete is that that parallel engine ?

pb4: 8 games in parallel ?

struct: yes pb4

Marchete: yes

Marchete: in PCR doesn't work

Marchete: it just explodes

Marchete: so many collisions that delta time drift

Marchete: unreliable

Marchete: in CSB it seems better

struct: That max is not what I really want

Marchete: ahh

struct: I want max index from a single __m256

struct: of the highest value there

struct: In csb it also did fine for me

struct: you seem to have higher average of sims though

pb4: What are you working on struct

pb4: ?

struct: csb

Smelty: ohh

Marchete: csb sim with AVX + what kind of search?

struct: I was going to try smitsi anyways, but I think the gains will be negligible

struct: I dont think there is a way to properly use it with mcts

struct: It will be all over the place

EliTheCoder: that's a lot of acronyms

pb4: struct you're making a "8 games in parallel" engine too ?

struct: yes

pb4: or an "8 times faster" engine ?

struct: 8 times parallel

struct: I already have one

struct: But never finished AI for it

pb4: 8 times parallel feels hard to use

struct: Is the "8 times faster" good?

struct: and how does it work?

pb4: "8 times faster" is obviously not really 8 times faster, but close enough

struct: So it might be even better than 8 times parallel

pb4: As for "good", it's convenient because you can use it just like a non-SIMD parallel

pb4: *engine

struct: So it makes a single game N times faster?

pb4: Yes

struct: ok, that is way more benefitial than 8 times parallel

pb4: :)

struct: Now I need to find how to do it :D

pb4: haha

pb4: Look at a normal CSB engine

pb4: Where is the bottleneck ?

struct: collisions?

pb4: more specifically ?

pb4: Finding the next collision ? Applying the collision that was found ?

struct: I think it was applying

struct: maybe not due to all the math inside next collision

struct: Well I would say its next collision

struct: You calculate it way more often

pb4: so

pb4: https://github.com/inoryy/csb-ai-starter/blob/master/main.cpp#L279

pb4: is slower than the double loop https://github.com/inoryy/csb-ai-starter/blob/master/main.cpp#L607

pb4: ?

pb4: :)

Default avatar.png ErrorRazor: Have you guys tried printing the inputs for all pods into error stream, then scraping replay data and teaching a neural network based on those inputs and outputs instead of using GA?

struct: So you calculate all the collisions at once?

pb4: two steps for all collisions

struct: I see

pb4: I could probably do one-step for all pod-pod collisions and a simpler step for pod-cp collisions

pb4: but I do two steps for all pod-pod AND pod-cp collisions

struct: its 10 collisions total right?

jrke: yes

pb4: Yes

jrke: 6 + 4

jrke: 6 pod and pod, 4 pod and Cp

jrke: i just discovered one of my major bug in SLCC code

jrke: the bug is in Pod and Cp collison i was taking Cp as pod with radius 600 and vx = vy =0 but forgot about its mass

Default avatar.png Alexhasapython: :disappointed:

struct: Thanks for the tips pb4

jrke: btw way struct with evaluation update and 2-3 more changes in inorry CSB starter you gan get top legend

pb4: haha

pb4: So your pods bounced on the CP ? :)

jrke: yes in slcc i just discovered in my mind that i forgot about CP mass and bouncing

pb4: Did you use inoryy's starter ?

jrke: not now

DetoBot: Would love to see a 8 Games in Parallel Engine. #struct

BlaiseEbuth: Erf. The code in the contest report is last submitted one, not the IDE's one... Just noticed. :(

sbdm666: hello

sbdm666: hows it going bois n girls

sbdm666: :joy:

BlaiseEbuth: :thinking:

Smelty: hm

nmortfeus: sheeeesh

jacek: mhm

KelvinAndHubbles: Why does the leagues have the "Promoting in X seconds" thingy where you have to wait?

KelvinAndHubbles: Is it so you dont get promoted off of like temporary success?

AntiSquid: you mean trying to demoralize you ?

AntiSquid: nah it's just a weird feature that's all

jacek: probably something with preventing server overload?

Westicles: There is an EU law that was put in place after all those WoW players died from bladder explosions

Default avatar.png ErrorRazor: Lmao I can't tell if that's a joke

Maxboyer: Is there any way to create a channel to discuss with some people ? (I see only World, but my collegue say he can see other channels)

Default avatar.png ErrorRazor: If you type a hashtag like #this you can then click it to join it, but idk if there's a way to create one privately

jacek: click on some #dupa and join there

Maxboyer: found it! the Help button seem usefull afterall :D

Maxboyer: (/join [channel name])

Mr.Pepper: (/leave)

Mr.Pepper: :p

ShannonNorris97: Has anyone done Nuggets numbers who can explain the problem differently to me please? I keep looking at the goal and the test cases, but I just don't understand what the puzzle is asking

jacek: that puzzle is so last week

BlaiseEbuth: Just eat all the nuggets. No more chicken, no more problem.

ShannonNorris97: Yeah I first looked at it last week when it was puzzle of the week, but wasn't sure about it, so I've just come back to it

jacek: you dont know what to do, or you dont know how to do it

AntiSquid: is your avatar suffering from vaccine side effects?

ShannonNorris97: I don't know what the puzzle is asking. So it says it wants the maximal nuggets its impossible to get. So even on the first test case where the portion sizes are 2 and 5, the answer is 3. Why not 1? You can't get 1 nugget

jacek: it asks about maximum

jacek: you cant get 1 and 3. 3 is maximum

ShannonNorris97: That's a good point haha, so why not 6 for instance?

jacek: because 6 is 2+2+2

ShannonNorris97: Damn, just got it

ramoRJ96: http://chat.codingame.com/pastebin/3c62389b-37d3-406d-ba4e-2f53e0b55df5

ramoRJ96: anyone knows the problem about this code ?

BlaiseEbuth: Is'nt that the exact same code than this morning ?

snoyes: what happens when you run it?

ramoRJ96: BlaiseEbuth yeah it's the same but I don't yet solve the problem

ramoRJ96: snoyes the 4th test failed

ShannonNorris97: Thanks for your help Jacek, I was totally misinterpreting the question and getting mixed up with the maximum aspect of it. I think I get it now

BlaiseEbuth: I still think that eating the nuggets will be simpler...

ShannonNorris97: Yeah that's true, maybe I should just do that instead...

AntiSquid: are they MRM nuggets or fresh chicken breast nuggets?

jacek: breast :yum:

BlaiseEbuth: Perhaps it's precised in the puzzle constraints...

ShannonNorris97: Sadly not, they let us down on this one

BlaiseEbuth: I hate under-specified contributions...

snoyes: ramoRJ96 The fourth test of what? Failed in what way? What was the input? What was expected?

jacek: i think its chuck norris

AntiSquid: bruce lee

ramoRJ96: yeah it's Chuck Norris

snoyes: ramoRJ96: and what does your code produce for that test?

ramoRJ96: the expected result is different from the result found

snoyes: I kind of assumed that.

AntiSquid: and it gives an error, correct? ramoRJ96

ramoRJ96: yeah but I don't know why ?

AntiSquid: might be because the code is wrong ramoRJ96

Mr.Pepper: is there something wrong with avatar :rolling_eyes:

AntiSquid: that stickman has 2 necks

Mr.Pepper: haha

Mr.Pepper: i meant avatar of others are not showing

jacek: huh

Mr.Pepper: oh good now :)

jacek: welp, my avatar is rotated a bit

Mr.Pepper: :D

ramoRJ96: yeah okey, It's possible I'm not really good with java

AntiSquid: ramoRJ96 you could try D https://www.tutorialspoint.com/d_programming/index.htm

jacek: you like the D dont you

AntiSquid: Automaton2000 give him what he thinks about

Automaton2000: hi all, is there a way to find out

jacek: AutomatonNN are you alright

AntiSquid: someone banned it?

AntiSquid: euler ? :thinking:

AntiSquid: bot lives matter

jacek: btw. what up with wednesdays and frogs

Mr.Pepper: wow what a relief after solving a puzzle

jacek: space maze?

Mr.Pepper: no , Scrabble :D

Mr.Pepper: i tried space maze , have to do one day

The_10x_Engineer: What problem can't be solved with something that Euler did :thinking:

AntiSquid: https://www.reddit.com/r/OutOfTheLoop/comments/6x0uvu/whats_the_origin_story_of_the_wednesday_frog/ second answer jacek

jacek: onitama

AntiSquid: some vine thingy

Marchete: I'm trying to implement jacekmax

Marchete: "Final selection: select move according to formula: move's eval value + log(move's visits)"

Marchete: "The final selection will mostly select move with highest visits, unless the eval score of less visited move is much higher."

Marchete: The latter?

jacek: hm?

Marchete: your playground

Marchete: has these 2 sentences

jacek: the second sentence is just observation

Marchete: and the first?

Marchete: log(visits)?

Marchete: what's that?

jacek: each move has eval and visits, so the formula is eval + log(visits)

jacek: move's visits

Marchete: why log?

Marchete: it comes from some theorem or smth?

jacek: arse-pulled actually. in mcts you choose most visited move

AntiSquid: tilt theorem

jacek: in jacekmax, it will most of the time still mostly visited move

Marchete: arse-pulled :D

Marchete: ok then

jacek: but if 2 moves have visit withing the same order of magnitude, then they are roughly equal and then eval of them is more important

jacek: like 0.5 + log(20000) vs 0.6 + log(18000)

Marchete: I just did the second part

Marchete: first most visits

AntiSquid: usually called magic number, not arse pulled

Marchete: except eval of another one was 1.05 the most visits

jacek: also it was a quick & dirty countermeasure against avoiding proven loss moves

Marchete: but arse pulled can be ok too

jacek: so i dont need to do ifs to exclude them

Marchete: it's a good idea

jacek: http://chat.codingame.com/pastebin/87846558-637e-4e05-8ba4-3fc2ee671e29

jacek: +3 so to avoid any NaNs and infs

Marchete: I'll ask you later about how to train that thing

Marchete: I'm not very fond of NN's

AntiSquid: why Marchete ? it's like brutaltester with extra steps

AntiSquid: NNs i mean

jacek: the other way to see this final selection is too see as using lower confidence

jacek: 1 move eval 0.4 and 10000 visits, 2 move eval 0.7 and 500 visits

jacek: i would choose deeper search over shallow even if the latter shows good eval so far

Marchete: it's note clear to me what to export

Marchete: or what to train

Marchete: value I imagine

Marchete: but I'm not still there

jacek: have you seen my tic tac toe n-tuples? it trains on all possible positions and their true values -1, 0, +1

AntiSquid: it's fine tuning some weights, the weights you export ax + bx2 + cx3 + ... all x

Marchete: no

Marchete: if you use chat.pastebin.com

jacek: https://github.com/jdermont/tictactoe-ntuple

Marchete: you seem to write a lot on chat :D

Marchete: hard to search on spdn

Marchete: also chat.pastebin isn't stored

jacek: spdn?

Marchete: https://cg.spdns.eu/index.php?title=Special:Search&profile=all

BlaiseEbuth: Jacek you're heeling to starboard...

Marchete: my NN are more "Tensorflowish" https://github.com/marchete/Mokka

Marchete: but I just did basic stuff

Marchete: like MNIST examples and things like that

Marchete: I need to replicate your tictactoe to see if it fits my code

Marchete: to reuse it in jacekmax

AntiSquid: tensorflow-ish = do it the normal way and import a model instead of writing from scratch ?

Marchete: yes

Marchete: and creating a NN model like in TF

Marchete: https://github.com/marchete/Mokka/blob/main/Mokka/Test_MNIST.cpp#L33-L42

Marchete: that's similar to "real" ML frameworks

Marchete: also AVX2 because why not

jacek: well this tic-tac-toe example is nothing more than perceptron

Marchete: but I'm dumb enough

Marchete: I don't have the knowledge to easily know how to train bots

Marchete: I mean you export N self plays

Marchete: best vs candidate

jacek: i see every evals as some kind of NN. chess material is just perceptron - a sum of chess piece values

Marchete: but what "export"?

jacek: N self plays? you mean positions?

Marchete: I imagine you did N self games, with O moves each one

Marchete: no?

jacek: you mean tic tac toe?

Marchete: I mean oware for example

Marchete: I imagine jacekmax did N depth moves per turn, and pick a best move

Marchete: but then, what?

Marchete: move + eval?

Marchete: move + win/loss?

Marchete: no idea

jacek: i train values only. so after like 1000 games you have 50000 (or more or less) positions. each position has label - the value of search tree

Marchete: as you see I'm pretty dumb

Marchete: that's like really basic NN

jacek: position - eval

jacek: when proven win = 1 and loss = -1

AntiSquid: if you didn't get it, then you're overthinking it (the weights i mean) like anyone else overthinks lots of stuff

jacek: (thats is if output of NN is tanh)

BlaiseEbuth: :persevere:

**BlaiseEbuth rotate jacek to the left.

jacek: constipations?

Marchete: position is the gamestate or a single move?

jacek: gamestate

Marchete: so tanh to limit to -1 +1

jacek: also, if not mentioned, values are always from perspective of 1st player

jacek: 2nd player would just take the negative from nn prediction

Marchete: gamestate + eval (or win/loss)

jacek: eeyup

jacek: BlaiseEbuth why rotate?

AntiSquid: blaise, that's his true face

BlaiseEbuth: You're askew... :(

AntiSquid: face angle i mean

jacek: lol, i googled askew

jacek: also, this is my subtle brain trolling. brain doesnt like subtle changes. at first i mirrored the face but no one noticed. so i had to take more extreme measures

BlaiseEbuth: I noticed the mirroring...

BlaiseEbuth: But was not disturbing

jacek: :(

AntiSquid: use pink and yellow as colors

AntiSquid: or purple and yellow ?

Marchete: why would you like to disturb people?

Marchete: that's disturbing

Illedan: What are you trying to NN Marchete?

Marchete: jacekmax

Marchete: oware

Marchete: I tried connect 4 with terrible results

jacek: i wonder what you put as input for oware

Marchete: hmm

AntiSquid: what did you use for connect 4 ?

Marchete: inputs?

Marchete: 6+6+2scores

AntiSquid: how many nodes per layer @_@

Marchete: each one for 0.04

Marchete: dunno!

Illedan: Why scores?

Marchete: why not?

BlaiseEbuth: why why ?

AntiSquid: what is 6 in connect4 ?

Marchete: not not?

Marchete: not, that's in oware

Illedan: Just more data to train when you really just want to maximize your current position

jacek: fair enough

Marchete: I'm a guetto NNer, mmkay?

jacek: guetto?

Marchete: stop questioning my networks

Marchete: undocumented/rogue/fake

Marchete: ghetto

jacek: oh

Illedan: Do you use TF?

Marchete: yes, I use TF

BlaiseEbuth: Who is he, what are his networks ?

Marchete: I mean, I can train with TF but I have no damn idea about how to do it properly

AntiSquid: just do it, don't let your dreams be dreams

Illedan: xD

jacek: "i can write but i cant read yet"

BlaiseEbuth: https://www.youtube.com/watch?v=UhRXn2NRiWI :3

Loth_Cat: hello people

Illedan: Marchete, go discord.

Marchete: no, people are weird there...

Marchete: jk

Illedan: :P

Illedan: :door:

jacek: discord? why not celestia

Loth_Cat: hello?

BlaiseEbuth: :wave:

Loth_Cat: how are you

BlaiseEbuth: Like a monday morning...

AntiSquid: a lot is happening on discord

Loth_Cat: I don't have discord so, what's happening

AntiSquid: wasn't talking to you

Loth_Cat: oh, sorry

jacek: oO

BlaiseEbuth: Rude

AntiSquid: it's ok, it apologized, relax

BlaiseEbuth: :D

BlaiseEbuth: "it"

AntiSquid: the chat critter

Loth_Cat: again, sorry AntiSquid if I annoyed you, I'm a curios person by nature

AntiSquid: not really, you would have to drop a long hellooooooooooooooo when nobody answered the second one

AntiSquid: so no worries

Loth_Cat: so, AntiSquid, how are you today?

BlaiseEbuth: :scream:

AntiSquid: that doesn't concern you

Loth_Cat: ok :grinning:

jacek: oh my

Westicles: Is this that FBI dude again?

Loth_Cat: is everything alright?

Loth_Cat: (you don't need to say, I'm just curios)

AntiSquid: no, we are about to go protest election results at the capitol

AntiSquid: peacefully

AntiSquid: mostly

BlaiseEbuth: The London capitol

BlaiseEbuth: For the UK elections

AntiSquid: no, nobody cares about that one

AntiSquid: murica is where it's at

Westicles: Oh, did the extremely far left party win over the extremely extremely far left party?

BlaiseEbuth: the extremely extremely far left party is a right party cause you've just done a circle right

AntiSquid: Joe Message isn't far left

Westicles: :thinking:

Smelty: :mask:

jacek: :upside_down:

AntiSquid: Automaton2000 -ban_spam

Automaton2000: but when i submit my code in the contest

Loth_Cat: soo, does anyone play any cool video games? (I'm just trying to start a conversation, nothing else)

AntiSquid: this website is full of cool video games (nothing else)

AntiSquid: https://www.codingame.com/multiplayer/bot-programming

AntiSquid: did you start playing a game yet Loth_Cat ?

Loth_Cat: no yet

AntiSquid: how's your bot Loth_Cat ?

Loth_Cat: huh?

AntiSquid: which game are you playing?

Loth_Cat: what do you mean?

AntiSquid: ok play this one then : https://www.codingame.com/multiplayer/bot-programming/penguins

Loth_Cat: I LOVE PENGUINS

Westicles: Why do the feds always pretend to be cats? First kitkat now this guy

AntiSquid: most feds like this game: https://www.codingame.com/multiplayer/bot-programming/xmas-rush it has no christ in xmas, thus 100% politically correct

Westicles: This has been debated at length. They took out the christ but left in the cross, so it is ok

jacek: do flintstones celebrate christmas

Loth_Cat: idk

AntiSquid: yes

Astrobytes: No. They are stones.

therealbeef: flintstones is so heretic. everyone knows the earth is only 6000 years old

AntiSquid: check the flintstones / jestsons conspiracy theories, proves they have christmas

AntiSquid: because they are both set in the future

therealbeef: ah flintstones is post-apocalypse?

AntiSquid: one of the theories yes

therealbeef: make sense

AntiSquid: the other is that jetsons are the rich people living above ground away from lowly flintstone peasants

Westicles: That explains all that Great Gazoo buisness

AntiSquid: why? gazoo is an alien

Astrobytes: When actually they were just American cartoons based on idealistic American lives?

Westicles: Gazoo built a doomsday machine

AntiSquid: oh found this : https://gunaxin.com/great-gazoo-hanna-barberas-best-villain

AntiSquid: ok fun stuff

Westicles: Ha, there you go

Loth_Cat: anyone herd of little nightmares 2?

Westicles: More of a Doki Doki crowd here I think

AntiSquid: i didn't like the first one and it clearly finished the story, what would the sequel even be about ?

AntiSquid: also heard, not herd

Loth_Cat: you didn't like little nightmares?

AntiSquid: chat critter herd :thinking:

Loth_Cat: uh well, little nightmares 2 is apparently a prequel and provides a lot more story for Six also, if you don't mind me asking, what didn't you like about the first game?

AntiSquid: everything or almost everything

Loth_Cat: I see

AntiSquid: the only reason i looked into it is because it was weird

Astrobytes: Never even heard of it

Loth_Cat: the world of little nightmares is very weird

AntiSquid: and wow, now the story progresses backward? she's off the island, should go build her Tropico6 resort or something

Loth_Cat: you mean the Maw?

AntiSquid: https://www.youtube.com/watch?v=V9LgTD9D15M

leojean890: Astrobytes I have just seen that you approved "ice and fire" :)

Loth_Cat: I'm pretty sure that if LN2 is a prequel, then Six wouldn't have been to the maw before this game started

Astrobytes: leojean890: Yes, it was after the SDK thing and had already been tested, it just needed approvals as the system had changed a little wrt community-made stuff

AntiSquid: that's the only community approved CG contest :D

leojean890: I've asked Blaise in the same time in #FR ^^ so I thought that you 3 validated the contest, but it's approval for the realease of a multi after the contest

AntiSquid: community approved community contest ?

Loth_Cat: imma get off now, bye

BlaiseEbuth: Violence is not an answer.

BlaiseEbuth: It's THE answer.

AntiSquid: too many deja-vu vibes from that chat critter

AntiSquid: as if i knew the critter from one of its past lives

BlaiseEbuth: Hmmm...

Astrobytes: AntiSquid: good luck with the letting agency/landlord thing. Not been on much today as I feel like shit, some cold or something

Westicles: Are colds still a thing?

Astrobytes: They never went away

AntiSquid: it snowed in oxford yesterday Westicles :D

therealbeef: icelandic ash

AntiSquid: no, it's just damn cold here

therealbeef: true, it being brittain

AntiSquid: and scots have it worse i am sure

BlaiseEbuth: With the kilt...

Westicles: Wait, can you get a cold without catching it from another person?

Astrobytes: ...

AntiSquid: only if you don't wear a mask when you're alone in your car Westicles

BlaiseEbuth: ^

Westicles: heh heh

AntiSquid: on a serious note though, YES

Astrobytes: yes what?

BlaiseEbuth: Just yes.

Astrobytes: IndyRef2?

AntiSquid: yes germs

therealbeef: germans?

BlaiseEbuth: Be like squid, say yes to the germs.

Westicles: Like if you are the last man alive but you walk around with wet hair

Astrobytes: Germs, the evil parts of seeds

therealbeef: being sexy for no use?

Astrobytes: Nah all that's bollocks Westicles

BlaiseEbuth: Last man will mostly walk around naked

therealbeef: truth

BlaiseEbuth: And so probably get a cold anyway

Astrobytes: You can affect your immune system through exposure [to the elements] but unless you've already contracted said virus this will not cause a cold.

AntiSquid: will get abducted by aliens, have a wife forged from his genes and restart civilization, they can't afford to end the galactic TV show BlaiseEbuth

BlaiseEbuth: Probably...

therealbeef: that reminds me, only 2 months until 5th season of Rick and Morty

AntiSquid: :(

AntiSquid: been waiting so long

Astrobytes: therealbeef coming with the real beef

therealbeef: got triggered by mention of galatic tv show :0

Astrobytes: I haven't actually fully caught up with s4 yet :(

Astrobytes: (I was a latecomer to the show)

AntiSquid: the train episode annoyed me to no end

**BlaiseEbuth has'nt seen a single episode...

AntiSquid: https://www.youtube.com/watch?v=lN5ZZ64P4PM BlaiseEbuth

BlaiseEbuth: I'll watch the show... One day.

Astrobytes: heh

therealbeef: there are already several universes where you have watched the show, BlaiseEbuth

BlaiseEbuth: I'm out. Galactic Nuts to everybody.

Astrobytes: gn BlaiseEbuth

Westicles: It is just okay. I've been binging Fat Albert, now that is a great show

Astrobytes: lol "Needful Things"

**AntiSquid gasps

AntiSquid: just ok ...

Westicles: It is a little too Family Guy for me, and I can't stand that one

AntiSquid: alright, i am going to step away from the screen for a while ... will take trash out

AntiSquid: family guy ... :(

Westicles: Well, okay maybe it is more like Archer. You like it at first but then it gets really old fast

therealbeef: like bojack horseman?

Smelty: o.O

Wontonimo: Astrobytes what's s4?

therealbeef: season 4 (of Rick and Morty)

Wontonimo: anyone else having issues with search race? Is it just me or are the validation case kinda tricky?

Wontonimo: normally I don't have issue with validation tests, like super rare

Wontonimo: i get it, they are validation, but man I'm getting stuck

Wontonimo: "Contrary to CSB, the positions are truncated and not rounded to the nearest integer even if the statement says so."

Wontonimo: man, why do i put off RTFM

struct: Did you fix it Wontonimo?


struct: I had a bug where the pod would stay 1 distance away from it

Wontonimo: Really? I have that same bug

struct: whats your eval function?

Wontonimo: it does this little dance trying grind it's butt up against the checkpoint or something

struct: Try doing depth search 1 to see if you still have that bug

Wontonimo: eval is total distance covered

Wontonimo: oh

Wontonimo: no, it's good

struct: Also if you eval every depth it should fix it

struct: I also had that bug on slcc

struct: But i have number of passed checkpoints - distance to next on eval

struct: I just increase the value of number of passed checkpoints

struct: So it values it more

struct: After that I could just eval at end

Wontonimo: i think i want to rewrite it. it is different enough from CSB or SLCC because there are zero opponents or obsticals

Wontonimo: i'm currently at 96th, but it was a fluke after many submits. (hangs head in shame). I think calculating the optimal path and using annealing could produce way better results

Wontonimo: after i fix my math

struct: The game is fun

struct: Also public referee

Wontonimo: oh right ... that's another thing i fail to check regularly

Wontonimo: thanks struct, i think i'll give it another crack soon. honestly I was just about to abandon it but you got me interested again

struct: np

struct: Also a small tip

struct: Some people move the pod when they find a collision with checkpoint

struct: you dont actually need to move it

struct: Same for csb

Wontonimo: what do you mean?

struct: So on csb when you collide with a pod

struct: you move all the pods to the time of the collision

struct: then apply the bounce

struct: for the checkpoint you actually dont need to move the pods

struct: you can just increase the nextcheckpoint

struct: http://chat.codingame.com/pastebin/b34a685b-96d0-4ded-9ec4-0acc181221e7

struct: That code was from slcc

Wontonimo: thanks

struct: When bot completed all checkpoints

struct: I taked into account the time of collision with last checkpoint on eval

struct: I also took into account the turn

struct: Just so pod rushes the checkpoint if its the last

Wontonimo: nice, i like that last checkpoint logic!

Default avatar.png Drew99Kt: you think doing these coding test make you better programmer?? i feel like a lot of this will never be used

struct: it improves your logic

struct: imo

Wontonimo: well practice will never make you better. you are either born with skill or you are not.

Wontonimo: like this bot https://www.codingame.com/share-replay/540191512

Wontonimo: not born with skil

struct: whats your checkpoint radius?

struct: 600?

Wontonimo: 598

Default avatar.png HellSys: hellop

Wontonimo: Drew99Kt i'm just messin with ya. yeah, i think for sure it stretches your abilities especially if you choose different langs and get out of your comfort zone

Default avatar.png Drew99Kt: yeah i know. just idk did good in all my classes but still struggling doing these coding test

Wontonimo: which ones?

struct: Sometimes it takes a little of time to click

struct: People can struggle a lot at the beginning

Default avatar.png Drew99Kt: i can code like 10 different programs using multiple tools and lanuages but these coding test making me feel dumb

Wontonimo: which one are you working on?

Wontonimo: setting reasonable expectations is super important. it isn't clash of code. some of them take me days

Default avatar.png Drew99Kt: i dont know how to share it

Wontonimo: url?

Default avatar.png Drew99Kt: https://www.codingame.com/ide/380721182fc889f622184f698734f67daf70fddf

struct: I think that is a clash

Wontonimo: ah

Wontonimo: my bad

Default avatar.png Drew99Kt: yeah idk i just havent been focused on trying to speed code, been trying to focus on actually building stuff. guess its time to grind away at this

struct: Have you tried the puzzles?

struct: The official cg ones should be better

struct: No time constraint

Default avatar.png Drew99Kt: https://www.codingame.com/ide/38072154688f2de4b5d377dae4a3a5f24158f3a9

struct: https://www.codingame.com/training/easy

Default avatar.png Drew99Kt: trying to do this one now

Smelty: let me see...

Default avatar.png Drew99Kt: ill check that out soon though

Smelty: I'm not allowed to see it

Smelty: try exiting the ide then sending

Default avatar.png Drew99Kt: https://www.codingame.com/replay/540192496

Smelty: um that's a replay

Default avatar.png Drew99Kt: yeah push play

Smelty: But it's called search race?

Smelty: i think you timed out

Default avatar.png Drew99Kt: yeah its called search race.

Smelty: I haven't tried it before, but I'll try it

Smelty: hmm...I think it's similar to coders strike back

Wontonimo: you can do the -3vel thing from CSB, it works well enough to score some CP

Smelty: (the expert rules are literally the same)

Wontonimo: hey Drew99Kt, CoC makes me feel stupid quite often also. Most people who have been on here a while dont do CoC

Smelty: xD same

Smelty: (also, there are so many test cases for the search race

Wontonimo: is test18 and validation18 the same?

Wontonimo: let me say that different ... is test18 the same in validation ?

Smelty: I have no idea

Smelty: I tweaked the -velocity*3 and got 100%, but..

Wontonimo: the suspense is killing me

Smelty: o.O
