thanhhv317: hello everyone

Laminator: helloooooooo

Default avatar.png LinhT.Nguyen: sup lam

Default avatar.png LinhT.Nguyen: that was weird as shit problem tho.....

Laminator: which one? lol

Default avatar.png hacker3d3d: hi

codeing: hi gays

codeing: tell me there #codeing

codeing: what you think about this puzzle

codeing: that's my answer

codeing: https://www.codingame.com/training/medium/count-of-primes-in-a-number-grid

codeing: http://pastebin.fr/69139

codeing: waiting answer there #codeing

codeing: is my code complexe ?

jacek: happy Caturday

Shrimpster: any free python bootcamps yall can recommend? My little brother is starting to code

Default avatar.png Tiki69: hey can someone help with a question? Minimun number of swaps to make an adjecent of an array equal exp-> [2,1,2,1] output 1 As Swap 2nd and 3 red index

Neumann: Are you guys using Beam Search in the top 8 of 2048 ?

eulerscheZahl: you should ask that on #ru

eulerscheZahl: i don't understand a word but they are actively discussing it by the numbers i see there

geppoz: i dont know how it is called,

geppoz: i create a full tree of a certain depth, say 8

geppoz: then i evaluate all the leafs, choose the best and i go up the tree for some steps, then i restart from there

geppoz: with that, i am above Euler :D

eulerscheZahl: (╯°□°)╯︵ ┻━┻

geppoz: that's enough for me :D

eulerscheZahl: what to expect next (not an optim): https://prnt.sc/v12mud

geppoz: that method of mine has a name?

eulerscheZahl: sounds a bit like beam search

eulerscheZahl: yet different

eulerscheZahl: and i doubt it's more effective than a regular beam search

geppoz: the difference would be to choose a set, not a single one to restart, right?

eulerscheZahl: and not go back multiple steps

eulerscheZahl: list of boards => expand all take best n

eulerscheZahl: repeat

geppoz: expand all => 1 step only?

eulerscheZahl: yes

eulerscheZahl: give it a try

Intp: https://www.codingame.com/clashofcode/clash/1423654aba198072da292d6c8f3740eb9fb0d6f

geppoz: i think that requires a very good scoring evaluation

geppoz: while going deep allows good results even with poor score eval

eulerscheZahl: it's not much different to what you do

eulerscheZahl: going multiple levels deep is the same as having a wide beam

eulerscheZahl: that is keeping many nodes

Neumann: What's your BS width euler ?

eulerscheZahl: you don't have to print everything up to the final node at the end

eulerscheZahl: const int searchDepth = 30;

   const int printDepth = 30;
   const int beamWidth = 100;

Neumann: wow

Neumann: You must have some fancy eval function

eulerscheZahl: http://chat.codingame.com/pastebin/738ecabc-a6c1-4870-a0a7-5507a1f8a4a8

eulerscheZahl: double result = 0;

           result += Grid[0, 0]; result *= 9;
           result += Grid[0, 1]; result *= 9;
           result += Grid[0, 2]; result *= 9;

eulerscheZahl: and so on, forming a snake

Neumann: wat

eulerscheZahl: i dont even score the game score

eulerscheZahl: just the number on each tile with different factors

eulerscheZahl: rewarding a large number in the corner

geppoz: fixed snake? i did double sided snake

eulerscheZahl: fixed for me. Ille has 2 snakes as well

geppoz: what means printDepth?

eulerscheZahl: i should also score "movability" only a single legal action that is RIGHT is deadly for me

eulerscheZahl: tried not to print all of my plan

Neumann: Why the top left-corner would reward 6561 times more than the bottom-left corner ?

eulerscheZahl: to recover from that RIGHT-only

eulerscheZahl: if that's 9^4, then yes

Neumann: I don't understand the logic of your eval :D

Neumann: Favor tiles stacked in a corner, ok

eulerscheZahl: did you ever play by hand?

Neumann: But why a corner more than another ?

Neumann: A bit yes

eulerscheZahl: give me a moment to make a screenshot

eulerscheZahl: https://prnt.sc/v12srs

eulerscheZahl: i reward snakes

Neumann: That I can see. But what if your screenshot was inverted, center-rotation

Neumann: Same board value

Neumann: Very different eval result

eulerscheZahl: for me it's the top left. but that's completely arbitrary

eulerscheZahl: just take 1 corner and stick with it

Neumann: Ok

Neumann: Interesting

geppoz: the important think is you dont reward two corners in the same board

geppoz: eval the "direction" of the board, and reward only toward any corner

geppoz: i do it for the two top corners

Neumann: brb stealing your idea

eulerscheZahl: i see you beating me soon

geppoz: i still didnt understand what do you mean with "print" depth

eulerscheZahl: while my beamsearch knows my plan for several turns, i don't print all of them

eulerscheZahl: you go some levels deeper to detect a dead end and go back up

eulerscheZahl: i just don't print everything

Neumann: How did you came up with that eval ? You figured out the game ? That's pretty smart

eulerscheZahl: too much playing by hand

eulerscheZahl: https://prnt.sc/v136f6

Neumann: Nice

wlesavo: Neumann yeah, mostly beamsearch with snake eval, at pure bruteforce with depth 7 i was at 28M

wlesavo: i think anyone who played the game came up with the same eval separately, which is pretty funny actually

Default avatar.png BoBot: exactly - I was like - "what snakes?!" and then when I saw the screenshot - oh yea I used to do that as well :D

codeing: hi gays tell me there #codeing what you think about this puzzle that's my answer

codeing: https://www.codingame.com/training/medium/count-of-primes-in-a-number-grid http://pastebin.fr/69139

Astrobytes: again codeing?

codeing: sure

codeing: i'm shaked

AntiSquid: codeine ?

AntiSquid: (pain drug)

codeing: explain

Astrobytes: I know, it take it 4 times a day

codeing: why pain drug ?

AntiSquid: because that's what it is

Astrobytes: codeine and codeing, different by 1 letter only

codeing: mhm

AntiSquid: Codeine is an opiate used to treat pain, coughing, and diarrhea.

codeing: codeing == code in present continuous

codeing: so code ing

Astrobytes: *coding

codeing: same

Astrobytes: You drop the e

AntiSquid: codeing is like short for treating pain with codeine

AntiSquid: the perfect verb for it

Astrobytes: "every day I'm codeing"

codeing: sure ?

Astrobytes: totally untrue actually

Astrobytes: anyway codeing, why are you showing everyone that code from hell again?

codeing: Astrobytes how is this code the hell ?

codeing: make me feedback there

codeing: #codeing

Astrobytes: we gave you feedback on it last night

codeing: you rigth

codeing: cya

Astrobytes: remember? Hard to read, inefficient, extremely verbose

codeing: what verbose ?

Astrobytes: You asked that last night too

codeing: was tired

Astrobytes: In this case, more code than required

Default avatar.png Tiki69: hey can someone help with a question? Minimun number of swaps to make an adjecent of an array equal exp-> [2,1,2,1] output 1 As Swap 2nd and 3 red index

codeing: oke

Astrobytes: Tiki69: https://lmgtfy.app/?q=minimum+adjacent+swaps+array

Sylarb91: can anyone guide me on the temperatures puzzle ?

jrke: in temperatures you have to output nearest int to 0

jrke: means minimum absolute value

Sylarb91: i already did that... let me be more specific

Sylarb91: i fail on the 3rd and 5th test because i dont know how i can output the positive value

jrke: use if else

thanhhv317: Hi

Sylarb91: yo

Neumann: wlesavo: How would you reach 28M with depth 7 ? 7 moves per turn doesn't allow you to get that high. Did you do several depth 7 BF per turn ?

geppoz: +1 (me too dont get that)

Default avatar.png Rodian: Can I restart coders strike back?

jacek: what do you mean by restart

Default avatar.png radwl: hi

wlesavo: Neumann yeah, several, you need around 30-40k moves, so once you reached depth 7 you add moves to the pool and continue the search

Neumann: Ok

Neumann: 4*depth7 give me WAY LESS score than you

wlesavo: its for 3 actions actually

wlesavo: but there was some tuning involved for sure

Neumann: 3 ? as in depth 7, then cut the at depth 3 and regrow from that ?

eulerscheZahl: UDL, no R

eulerscheZahl: or whatever fits to the shape of your snake

Neumann: Oh

wlesavo: yeah, what euler said

wlesavo: and also what you said :slight_smile:

eulerscheZahl: was Ille's idea initially

eulerscheZahl: meanwhile I uploaded my next brainfart :imp:

Neumann: Is that even a thing ? Ignoring one direction

wlesavo: yeah, after he claimed 3 actions is enough for 40 mil i tried that

wlesavo: actually now we know its enough for 50m

wlesavo: Neumann i was also sceptical to that

jacek: what a ripoff of other puzzle

wlesavo: well the real deal is to solve all of the 14 test with 131k's

jacek: i love the windows 98(5?) graphics

jacek: but isnt it copyrighted or something?

AntiSquid: excuse me i got 39k first with doing just ULR . Automaton2000 say somthing

eulerscheZahl: i even downloaded a virtual box disk for that

Automaton2000: i hate when that happens

AntiSquid: yes

eulerscheZahl: i think it's save to call it abandomware

jacek: there is 4:02 PM in the corner. can you make it to show actual time of the replay? :v

eulerscheZahl: :D

AntiSquid: but technically what you need to check for is that you keep the highest number in a corner for as long as possible so if you can move any direction as long as you don't move your highest

eulerscheZahl: wanted your ideas for some nonsense desktop icons

eulerscheZahl: but i like the clock idea

wlesavo: euler what about n-dimensional minesweeper? :smiley:

jacek: nonsense?

eulerscheZahl: finally a use-case for the three.js library

eulerscheZahl: as in: stupid programs that fit in the time

eulerscheZahl: like browser toolbars

jacek: daemon tools or winamp

AntiSquid: add a desktop icon with random anime avatar and text: secretly a fan

eulerscheZahl: leave me alone with your anime

AntiSquid: omg

jacek: yeah, use ponies instead

AntiSquid: gross ... bronies are weird

jacek: weeb

eulerscheZahl: maybe some torrent program

eulerscheZahl: or a napster link

AntiSquid: maybe a "my little pony" avatar with the text "dark web" underneath ... yeah sure

AntiSquid: outdoor cam desktop item !

eulerscheZahl: or good ol' winrar

AntiSquid: or "neighbour's backyard cam" ?

AntiSquid: is this just for the cover image euler ?

eulerscheZahl: for the background of the game

jacek: https://www.oldapps.com/os/Windows_98

eulerscheZahl: messengers, of course!

AntiSquid: oh yes limewire ! the first best source of viruses !

AntiSquid: mcaffee antivirus internet explorer 4

if you are going for crappy old stuff

eulerscheZahl: how do i go online and download things? it tries to detect my modem

jacek: delete system32

AntiSquid: sure i have a drive with a bunch of system32 on it just so i can delete when whenever i see that comment

AntiSquid: delete one *

jacek: linux hasnt system32 and see how fast it is

AntiSquid: out of curiosity what do you use jacek?

AntiSquid: also windows has bloatware so your comparison is unfair

jacek: arch linux

AntiSquid: upgrade to black arch now

Illedan: Oh, Minesweeper contri :O seems fun

eulerscheZahl: i still have to fix the system clock. it's stuck :D

Illedan: OH

Illedan: Do it in JS?

Illedan: Would be very cool if you added a dummy start menu to :D

eulerscheZahl: :D

eulerscheZahl: when you load the replay, it already shows the correct time

eulerscheZahl: that part is done in JS

Illedan: aha

jacek: while youre at it, why dont you make fully functional windows 98 in js

Einwickler: jacek like this: https://98.js.org/

Illedan: wow, some people have too much free time

Einwickler: yep

Einwickler: there is a ms paint on github somewhere too

jacek: ohh and it has minesweeper

jacek: no need for VM now

Illedan: euler stole it from there :O

Einwickler: Oh boy I just figured its the same guy who made these

Einwickler: wow

Einwickler: But thats my favorite: https://1j01.github.io/pipes/

BiMathAx: Hello, what do you think of my new contribution ? https://www.codingame.com/contribute/view/5581506ad04331f4020bef765773d3759587


BiMathAx: Thank's

DomiKo: I think that statement is too long

jacek: you read statements? :o

DomiKo: no

DomiKo: but i can see that it is long

DomiKo: :sweat_smile:

BiMathAx: Xd

DomiKo: ohhh that's English + French

BiMathAx: It's because she is in English/French

DomiKo: now I don't know if that's legal or not

jacek: its a crime

DomiKo: French could be crime

eulerscheZahl: AntiSquid did you just self-upvote your comment?

AntiSquid: it's a good comment

DomiKo: own comment is always good one

eulerscheZahl: that would be a good comment if i would have written it DomiKo

AntiSquid: btw i still remember the order on every machine was: My computer, recycle bin, network

jacek: what is the round limit in checkers? 300?

Laminator: isn't it infinite if both sides get kings?

jacek: on CG

AntiSquid: it's never infinite, one of the players would die in real life before the game ends .

Sylarb91: imagine that happening

Sylarb91: a game from childhood till burrial

MSmits: Laminator you can have multiple kings in checkers and if you have more kings than your opponent you will usually win

MSmits: you do get some extremely long solved wins though. I think with more than 10 pieces, some solved games have a PV of 400+ turns

MSmits: so that's the fastest you'll win in those cases

jacek: i see there is 300 turns limit

MSmits: yeah, so in CG the solved wins/losses/draws are different

MSmits: well.. only in the sense that some won games will be draws

MSmits: all draws will still be draws

MSmits: this is reflected on the leaderboard btw. Way too many drawn games.

MSmits: also because these end games are so long, the searches cant find a route to the win even if it does exist, so you get silly loopa

MSmits: loops

MSmits: if someone ever makes a chess game, this will be far worse even.

MSmits: needs a point win rule. if you're ahead by x points it's an automatic win. Otherwise way too many games will get stuck even though it's obviously a win for one side

jacek: nah, in chess it is more complicated

MSmits: what is

jacek: points and the endgame

MSmits: I mean I know the game is more complicated and material isnt everything, but after 300 turns, the game is likely stuck in a loop

MSmits: you could make it +15 point difference for the win or something

MSmits: and you dont apply the rule until after 300 turns

MSmits: in real chess tournaments there is a referee making a decision like this also

MSmits: well the one i was in when i was young anyway

PatrickMcGinnisII: start making baby pawns at turn 200, heh

MSmits: lol wut?

PatrickMcGinnisII: bored pieces make babies

MSmits: sounds like i've been playing chess wrong

MSmits: ahhhh

jacek: thats cheese

Allis: @MSmits Not necessarily "stuck in a loop", but threefold repetition of the position is very likely to have occurred by move 300.

MSmits: mmh true

jacek: dunno. detecting 3-fold repetition would be pain

PatrickMcGinnisII: drop random glasses of beer, drunk pieces can bend the rules

Allis: I would be shocked if there weren't a chess position hashing algorithm by now.

jacek: zobrist eh

jacek: hmm my checkers bot seems to be working bugless. move representation was pain

Allis: What'd you use?

jacek: for now, negamax

eulerscheZahl: finally, my clock is working

PatrickMcGinnisII: No Stress Chess would work, no repeated moves checks. level 1, 1 card, level 2 3 cards level 3 5 cards, yup that would do it

MSmits: jacek yeah... checkers is a pain to simulate with the jumps

MSmits: oh and eulerscheZahl grats on fixing time. Though without you my vacation would never end :(

jacek: hm?

MSmits: sorry, responding to some old chat :P

MSmits: I had new ideas about oware endgame books

MSmits: turns out even though you need a different result for each turn because of the limit, they have patterns. So i can save a bunch of time

MSmits: and I can keep generating the endgame book while still on my opening book

MSmits: maybe if I use all these new ideas I can finally win some games vs you jacek :P

MSmits: still only have a 20-30% winrate with my best versions

jacek: good

jacek: its boring being the 1st

MSmits: in a way it is yeah

jacek: no motivation to improve

MSmits: I would not mind working on yavalath more, but you're right, no motivation

MSmits: I'll help you out, just give me another month or two

Default avatar.png boon-cpu: h

MSmits: I got you

MSmits: :)

jacek: gotta rent that supercomputer eh?

MSmits: maybe as a last resort :P

MaliciouslyCrypticUsername: .-.

MaliciouslyCrypticUsername: 25 more days...

jacek: AutomatonNN, who is the biggest noob

AutomatonNN: want to be a teacher for the contest

MaliciouslyCrypticUsername: jacek is the biggest noob

MaliciouslyCrypticUsername: CLashes are getting easy...

AntiSquid: AutomatonNN i see people getting friendly in chat

AutomatonNN: eulerscheZahl is there a way to see a bot to get top 10 or something ?

jacek: MSmits ever heard of SHOT? :O https://hal.archives-ouvertes.fr/hal-01436255/document

DomiKo: Jacek you are using some fancy enhancement in UTTT, right?

jacek: not that fancy, but yeah

DomiKo: maybe one day I'll make something work that well

DomiKo: right now everything is a lot worse or very similiar :(

jacek: how can it be worse?

DomiKo: some enhancement are really slow

DomiKo: and they perform very bad :(

jacek: many of "general" or "knowledge-free" enhancements works mostly only for go, maybe hex/havannah

DomiKo: now I know

DomiKo: why they never use UTTT in papers

jacek: mmh

jacek: Automaton2000 do you like UTTT

Automaton2000: i think they should be able to help me with my code?

Default avatar.png IAmNewHere: ERROR: ld.so: object 'libstdbuf.so' from LD_PRELOAD cannot be preloaded: ignored.

Default avatar.png IAmNewHere: what is that

jacek: just a warning, nothing to worry about

DomiKo: Automaton2000 why nobody likes UTTT?

Automaton2000: only for the current one

jacek: reBless loves UTTT

DomiKo: I know how much

DomiKo: that much as clashing

MaliciouslyCrypticUsername: AutomatonNN ping euler

AutomatonNN: eh

Astrobytes: jacek: Sequential Halving Applied to Trees should have been SHAT. Probably not good in language filters :P

Nerchio: what are you looking for

MSmits: http://chat.codingame.com/pastebin/974ee0dc-7963-44e9-91b4-c767a5c6954c

MSmits: aw damn, nvm :)

AntiSquid: it's past midnight, don't you guys ever sleep?

AntiSquid: seriously, Automaton2000 what do you think?

Automaton2000: maybe not as much as u want

MSmits: think more AutomatonNN

AutomatonNN: MSmits i dont know if it is a lot in the forum

MSmits: err automaton2000

Automaton2000: because i am a bit confused

MSmits: me too now...

MaliciouslyCrypticUsername: AntiSquid it's only 4:53 pm for me

BenjaminUrquhart: what is sleep

BenjaminUrquhart: yes I came here just to say that

BenjaminUrquhart: now I'm gone

MaliciouslyCrypticUsername: Oh

MaliciouslyCrypticUsername: Bye then

Default avatar.png jr7vn: :D

MaliciouslyCrypticUsername: Im trying to move my target point slightly towards the next checkpoint so I turn in the rght direction

BenjaminUrquhart: coders strike back?

BenjaminUrquhart: yes I'm back hi

Default avatar.png rcadwell: Just started using this site. Seems pretty fun for learning and expanding my skills

MadKnight: just subtract 3v MaliciouslyCrypticUsername cmon

MaliciouslyCrypticUsername: All that does is make me turn earlier. I need to turn in the right direction
