cheesecake_assassin: Hey
Wontonimo: solved it
Wontonimo: i guess i'm lucky now
Wontonimo: gn all
martinpapa69: any c4 expert here ?
cheesecake_assassin: fbi wants your location
martinpapa69: fbi does know my location
cheesecake_assassin: Hot!
Wontonimo: i'm okay at c4
Wontonimo: 19th
martinpapa69: I checked this bitboard article for c4. and he has a bitshit isWin function
martinpapa69: but i cant leave 1 row and 1 culomn free
martinpapa69: what now ?
Wontonimo: what article?
martinpapa69: https://github.com/denkspuren/BitboardC4/blob/master/BitboardDesign.md
Wontonimo: my encoding just uses 1 uint64_t per player
martinpapa69: yes
Wontonimo: the article is a 6x7 board
martinpapa69: yes
Wontonimo: what's your question?
martinpapa69: he utilizes a free row and culomn for a fast is_win function
martinpapa69: do you have any solution for that ?
martinpapa69: as we dont have enough space
Wontonimo: yeah
martinpapa69: mind sharing ? :D
eulerscheZahl: there are 2 ways
Wontonimo: one solution is to use uint128_t
eulerscheZahl: 1. use int128_t
Wontonimo: oh, thanks euler. it's late for me
martinpapa69: noo
martinpapa69: i want to use int64
eulerscheZahl: 2. use the 64 bit version. and before checking for remaining 1s you do a bitmask that completely hides a part of hte bitboard
Wontonimo: ^^ me too
martinpapa69: that was my idea too
Wontonimo: ng
eulerscheZahl: e.g. when you shift up for vertical rows you do board & 0b00011110001111...
eulerscheZahl: for me the int128 was faster
martinpapa69: to mask the map around the last played piece in 5 radius
martinpapa69: so i cant step out of the map
eulerscheZahl: just mask in regards to row check direction regardless of the played bit
martinpapa69: or just max the farthest sides
martinpapa69: mask*
martinpapa69: ye something like that
martinpapa69: okay so some drawing homework for me i guess
eulerscheZahl: pretty simple to find the masks
eulerscheZahl: i had them but deleted
martinpapa69: or i will just bruteforce a mask for every position
martinpapa69: at start
eulerscheZahl: still a bigger lookup array for your masks
martinpapa69: or ill calculate a distenca from the bit, which is '1', after i apllied the bit operations of the is_win func
martinpapa69: from the last used piece
martinpapa69: if its greater than 4 its a false positive
martinpapa69: ye, thats what ill do
eulerscheZahl: i have doubts about the correctness of this
martinpapa69: its correct
eulerscheZahl: place a 1 in the middle vs at the top with some 1s at the top of the previous row
eulerscheZahl: what's the difference in those cases?
martinpapa69: the bitsifts go in one direction
eulerscheZahl: this time you typed the f in bitshift :)
martinpapa69: :D
martinpapa69: the distance cant be greater than 4 ever
eulerscheZahl: i'll just trust you to get it right. and if it's wrong, it's not my problem anyways :)
martinpapa69: :D
ProCoder03: where can we learn Trees in C# ??
xxd: class Node
xxd: how is the performance of int128's?
xxd: are they native?
xxd: the extra row+col strategy is interesting, but i'm not sure if MSmit s allowed_moves function still works
michaellan: i think it'll work with some tweaking
michaellan: but i think the mask idea is a bit less hectic, altho euler says its slower :sad:
Almin5k: Goodmorning everyone, if you’re changing the world, you’re working on important things. You’re excited to get up in the morning.
Westicles: Repetition is how we learn!
ProCoder03: @Westicles, I can understand we need to practice , But the conceptual knowledge ???
Westicles: I was referring to Almin5k's copypasta from yesterday
Almin5k: It comes from the heart
peppers: u really a philosopher bro.
Almin5k: thanks man
ProCoder03: So we need to learn from other's code, Thanks @Westicles !!!
Westicles: Yeah, Larry Page was quite the prophet
ProCoder03: i don't understand ??
Westicles: Almin5k is quoting Larry Page
Almin5k: No Larry Page is quoting me
Almin5k: im the ghostwriter
peppers: imm curious about how u guys learn english...some question really really hard to understand
KRALLEE: HELLO GUYS THE KING IS HERE
Almin5k: Godmorning spongebob
KRALLEE: BOW DOWN SQUIRREL
Uljahn: you can't be the king here if you suck at coding sorry
KRALLEE: NEW ACCOUNT AND BOW DOWN U CAT
Uljahn: why so caps and rude? guess i should kick you
KRALLEE: MY KEYBOARD IS BROKEN I CANT FIX IT
Almin5k: good vibes only:raised_hand:
Almin5k: Every breath we take, every step we make, can be filled with peace, joy and serenity.
MrKovi: Hello guys, i just joined codingame, i am trying new ways to learn coding, i am currently learning python, any advice for me?
Uljahn: besides using search?
MrKovi: it depends if you have better advice than just using search, for every problem
Uljahn: this site is meant for practice, it could be hard for a complete beginner to start here
Uljahn: so i'd suggest to use some tutorials on the web
MrKovi: I have completed courses over python, i just didn't find the right motivation to start practicing, with a little practice and competition.
Uljahn: ah, i see. have you tried bot AI games?
MrKovi: not yet
Uljahn: try this https://www.codingame.com/multiplayer/bot-programming/coders-strike-back
Uljahn: if you don't like it, there are more
MrKovi: thank you, i will search for more!
elio27: The others are much harder
elio27: Or maybe I'm just absolutely stupid
Armin_programmer2010: hello everybode
Armin_programmer2010: everybody
Armin_programmer2010: :sweat_smile:
elio27: hi !
Armin_programmer2010: how are you?
Uljahn: btw some multis provide a list of valid actions for your bot, so you can simply choose one of them
Armin_programmer2010: hey guys how can i anwer multiply anwers in coC in print
Armin_programmer2010: i mean clash of codes
Uljahn: which one?
elio27: in one line or each in a different line ?
Armin_programmer2010: in reverse mode
Armin_programmer2010: in one line
Armin_programmer2010: please answer
Almin5k: A hello sends a message of welcome of acknowledgment and of worth. To ignore someone is to say to them that they are not worthy of your attention. Make it a point to say hello, warmly, and with a smile.
Armin_programmer2010: what!?
Almin5k: Hello :)
Armin_programmer2010: ok:smiley:
KINGGGGGGGGGGG: hi
KINGGGGGGGGGGG: hello
Almin5k: Hello king, what you know about rolling down in the deep?
KINGGGGGGGGGGG: ok
KINGGGGGGGGGGG: when the brain goes numb u can call that mental FREEEEZEEE
KINGGGGGGGGGGG: guys u wont believe what happened a guy named christian just dropped my airpods and now im very much sad and depressed faze up guys
Uljahn: are you guys really interested in coding? if not you'd better find another place for casual chit-chat
KINGGGGGGGGGGG: SO WE'RE ARE NOT ALLOWED TO SAY WHAT WE WANT MAN ISNT THIS FREEDOM OF SPEECH OR WHAT AM I RIGHT Almin5k???
Almin5k: Nobody is perfect. We all make mistakes and do things that hurt other people at some point in our lives. That’s why it’s important to acquire the ability to acknowledge your mistakes and apologize for your wrongs, even if you didn’t do it on purpose. Im sorry
KINGGGGGGGGGGG: preech
Uljahn: you have been warned btw, you are free to discuss coding related topics here
Uljahn: Almin5k: there's no need to copy-paste random quotes in the chat, it's a warning
Almin5k: Okay sorry i will stop preaching, but it comes from the heart:fist:
KINGGGGGGGGGGG: DO U EVEN HAVE A FUCKING LIFE MAN GET SOME BITCHES ON UR DICK MAN HOLY SHIT U SIT AT HOME PROBABLY LIK 30+ RIGHT NOW AND MODDING ON A GARBAGE ASS SITE THAT NOBOBY CARES ABOUT IF U THINK YOUR THE BOSS THEN THATS REALLY PATHETHIC MY BROTHER PREACH AND #BLM FOR OUR FUTURE FREE MY MAN KRALLEE HE AINT DONE NOTHING!!!!!!!!!!!
Uljahn: flooding the chat with offtopics is disrespectful to the community
Acquira: http://chat.codingame.com/pastebin/16fecaa7-0127-4daf-ba65-36fb97ab1c26
Acquira: wait It automatically went to a pastebin for a smaller message than king's spams.
Uljahn: your message has too many linebreaks i guess
MounirEnmeiRyuu: hello !
is the source of DeepMind's AlphaZero chess available somewhere ?
Acquira: Indeed, that might be the case.
Uljahn: MounirEnmeiRyuu: dunno but Automaton2000 algorithm is available here on CG
Automaton2000: how good are you at now?
Uljahn: Acquira: im not proficient with php sorry
MounirEnmeiRyuu: Ok, thanks
martinpapa69: alphazero source is not puplic, but there is a public replication
martinpapa69: https://github.com/LeelaChessZero/
Uljahn: Acquira: my bet is to use debug output to see what is happening
realBillGates: hi guys
realBillGates: i need some help with "imagine" coding if u know what that is
b0n5a1: Hi !

Uljahn: MCTS is for top gold/legend
ProCoder03: then for bronze ??
Uljahn: im midgold with flat UCB1
Uljahn: random for bronze i guess
ProCoder03: Nahh... I tried random
ProCoder03: only top 100
Uljahn: add some win checks

kolpaja: i m new here,
TobiasA: sorry for late reply
ProCoder03: np ..
kolpaja: what do you suggest me to start doing?
ProCoder03: then how ??
ProCoder03: kolpaja: try descent and temperatures
TobiasA: i checked all the available moves and chose the one that leads to a win in either miniboard or mainboard
Atanasius: p
Atanasius: p

Wontonimo: thanks Astro
Astrobytes: you're welcome
Lekrkutj: how did u guys learn to code
Astrobytes: Practice.
Wontonimo: wow, the list of CG mods on the list is large today
Uljahn: start simple
Wontonimo: i started by transposing choose-your-own-adventure stories into if/else code with lots of prints
Astrobytes: Yeah. Everything builds on the basics. Without having a solid foundation you won't get much further.
Astrobytes: Wontonimo: good example. Also simple word games, guessing games etc.
Wontonimo: actually, not even if/else. it was GOTOs !
Astrobytes: :D
ProCoder03: Wow !!! one of Linq is working while the same in another is not working
ProCoder03: what a weird situation !?!
darkhorse64: wontonimo: is there a "PID for dummies" somewhere ? I am curious about your approach. I have used GA only for ML2/3 for optimization purposes
Wontonimo: this is the "easiest read" i've found https://w3.cs.jmu.edu/spragunr/CS354_F17/handouts/pid.pdf

ProCoder03: I am not even getting the Count of list , it is just blank !!!
alowaniak: None of the UBoard[1-8]==0?
ProCoder03: nahh... every thing is zero in the start
ProCoder03: public int[] UBoard = {0,0,0,0,0,0,0,0,0};
Uljahn: add more debug outputs to be sure
KRALLEE: hey guys
Wontonimo: hey spongebob
ProCoder03: This is awesome !!! , the same code in my history works. But now it isn't :sob:
Wontonimo: that doesn't sound awesome. perhaps we have different definitions :P
ProCoder03: sarcasm !!!
Wontonimo: me too !!!
ProCoder03: I copy pasted my code and now its completely broken....
Wontonimo: hey darkhorse64 , tbh about Mars2 I didn't do "all of it" as PID. Just the X direction is PID controlled using a gentle banking of around 15 or 28 degrees and thrust 4 as the "steering" to get over the landing pad. Then switch to Mars1 logic for landing
Wontonimo: no collision detection, just landing detection
darkhorse64: Hover than land. Got it !

Wontonimo: finished "The Lucky Number" yesterday (that's not the interesting bit). What was surprising is that it took 0.0024 seconds for my python code to solve it. I thought it was going to be fast enough, but that's overkill
Q12: Nice!
Wontonimo: not just python, but hacky string manipulation with splits instead of integer math
elio27: hey, what's the easiest bot battle exercise after coders strike back ?
Wontonimo: easy in what way?
Wontonimo: easy to start and get something working or easiest to get to legend?
elio27: oh yeah sorry I forgot to precise
elio27: easiest to start
Wontonimo: there are a few multis where all the legal moves are provided in a list on every turn. These are pretty easy to start because you can make a basic bot that just picks one move randomly
Wontonimo: Spring Challenge 2021, Ultimate Tic Tac Toe fall into these
jrke: tron can be easy start i think
Wontonimo: Something like Tron is pretty easy because there are just 4 directions
Wontonimo: and you can do well just by going in the same direction as last time, or turning if you are going to crash
elio27: Okay thank you !
Wontonimo: if you know flood fill so you can make an informed decision about how much space is available, even better
Wontonimo: Connect 4, also fits into the category of fairly easy to start. There are only 9 moves (and 1 steal)
jrke: oware!! only 6 valid moves at max
jrke: Tron 4 moves at first turn then 3 moves max
Wontonimo: yeah! are the moves listed in the output?
Wontonimo: for oware?
jrke: nope
Wontonimo: which one interests you elio27?
elio27: I think Tron
jrke: depth 1 is enough for tron if i am not mistaken
elio27: It looks cool and interesting at the same time
jrke: till silver league
Wontonimo: yeah, i got to silver with depth 1
rndmlck: can someone explain to me what you have to do in the reverse mode with the numbers? A little pointer in the right direction would do a lot. I try to figure it out but I have no idea... It's not binary at least.
elio27: I will try, thanks !
Wontonimo: wait till the clash is over and look at other peoples solution
Wontonimo: that's the easiest
rndmlck: Thank you, didn't know that was possible
jacek: the point of reverse clash is to find it yourself
BlaiseEbuth: You mean... Thinking?! :scream:
ManeatingGhostOfDeath_6d14: hi
FiveRivers: For the race I've unlocked the ability to use "BOOST" but when replacing the power value with "BOOST" as it says, I receive an error saying BOOST is not defined.
FiveRivers: code: console.log(nextCheckpointX + ' ' + nextCheckpointY + ' ' + BOOST)
Wontonimo: console.log(nextCheckpointX + ' ' + nextCheckpointY + ' BOOST')
Wontonimo: there you go
FiveRivers: Alright, so the output needs to be boost and it isn't a defined variable. Thanks.
Wontonimo: the only defined values are the ones in your code

Wontonimo: that's strange, some random numbered chat tabs showed up and I haven't been doing anything other than the musical scores challenge
Astrobytes: known bug
Astrobytes: (cause unknown)
Astrobytes: ah grats on lvl 30 :)
Wontonimo: thanks. maybe being level 30 makes me able to drink milk
Wontonimo: i'll try it out
Swyfti: but don't we already drink milk?
Wontonimo: yeah, i was just thinking about how dumb that power would be. Man, why would they even make that the level 30 unlock? CG is strange
Wontonimo: you'd think they'd make it more useful, like moderation of profile pics
Astrobytes: I don't drink milk.
Astrobytes: levelling up is levelling up.
BlaiseEbuth: So deep...
Astrobytes: :D
MounirEnmeiRyuu: I used alpha-beta search in the ULTIMATE TIC-TAC-TOE, and got ranked 69th in the Gold ranking.
MounirEnmeiRyuu: do you think alpha-beta search cannot be better than monte-carlo ?
Astrobytes: MounirEnmeiRyuu: nice one! There are alphabeta bots in Legend league
Astrobytes: Most use Monte Carlo tree search though
jacek: its difficult to come up with decent eval in uttt
jacek: so this is good ranking
Astrobytes: yep
Wontonimo: are you using bitboard MounirEnmeiRyuu ?
MounirEnmeiRyuu: no bitboard, just simple optimized C code
Astrobytes: pragmas?
Zyabrik10: Send a message to say hello!
Astrobytes: bitboards and/or the right pragmas and you'd be in Legend
Wontonimo: well, bitboard could probably increase your depth by another 2
Astrobytes: Need to know if he has the pragmas
jacek: the suspense is killing him
Wontonimo: if you arn't using killer move, that could also equal another 1 depth
jacek: killer move in uttt?
Wontonimo: why not?
jacek: uttt is very context based
Astrobytes: maybe history heuristic
Wontonimo: alpha-beta killer move
Swyfti: i like ultimate tic-tac-toe irl with my friends
Wontonimo: you don't think it would help jacek?
MounirEnmeiRyuu: okay, I see
jacek: whenever specific move would be available, the entire board will be quite different. i never tested, i think it wont work much
Astrobytes: the code is compiled with no optimization MounirEnmeiRyuu, so you have to specify things via pragma directives
Wontonimo: it's a general and safe optimization on top of alpha-beta pruning that sorts the moves as to maximize pruning
jacek: i know
DR_IQWDJ: is there a way to input nested arrays like [1,[1,3,[1]]], when making a contribution?
Astrobytes: I haven't checked either but not sure it would work in UTTT. ID with best last depth move sure
MounirEnmeiRyuu: I mixed the alpha-beta with iterative deepening in fact, starting from depth 8
Astrobytes: Nice.
MounirEnmeiRyuu: it reached usually depth 13, 14 by the end game
MounirEnmeiRyuu: I occasionally beat MightyCarlo, but he wins most of the time
Astrobytes: A bit more optimisation and you'll be Legend for sure.
MounirEnmeiRyuu: do you the mean the code is built in debug mode ?
Astrobytes: Yes.
MounirEnmeiRyuu: then what is the pragma to enable this optimization ?
jacek: #pragma GCC optimize "Ofast,unroll-loops,omit-frame-pointer,inline"
- pragma GCC option("arch=native", "tune=native", "no-zero-upper")
- pragma GCC target("rdrnd", "popcnt", "avx", "bmi2")
jacek: add this as first lines (above the includes
Astrobytes: Also, check this:
https://tech.io/playgrounds/58302/using-pragma-for-compile-optimization
jacek: by saying alpha-beta, im assuming you mean iterative deepening
AllYourTrees: must be nice to be able to specify compile args in code :eyes:
Astrobytes: Eh. You chose to side with Ferris!
AllYourTrees: ya just being crabby :D
AllYourTrees: its part of the job
Astrobytes: :rofl:
MounirEnmeiRyuu: thanks!
jacek: is it faster?
MounirEnmeiRyuu: i'm testing it out
MounirEnmeiRyuu: It doesn't seem to be better, but maybe I need to tune some timing parameters. Will check it later.
Thanks anyway!
michaellan: Swyfti: UTTT is opaque
Takos: hello, has anyone worked with CodinGame API? in that case where could i get a list of all notification types and type groups?
thanks in advance
Swyfti: uttt is opaque? it is not transparent? what does that mean xxd
Swyfti: xxd: is there something special about ultimate tic-tac-toe?
michaellan: its not trivial for a human to determine the state of a UTTT game
michaellan: i.e., given a position, determine who's winning/losing
MSmits: Astrobytes I still want to try for that article. Do you think people will appreciate if I explain how to generate an endgame book for oware?
MSmits: I think i'd like writing that
MSmits: I mean an ingame one btw
MSmits: not this local craziness that I do
Astrobytes: I reckon so yes MSmits
MSmits: allright then, I'll try to finish that this week then
Astrobytes: You've accumulated a wealth of knowledge
MSmits: yeah there's a couple games on CG i could talk about for hours
Astrobytes: Is that just an excuse not to finish your NN? :P
MSmits: err mostly not :P
MSmits: but maybe subconsciously some
Astrobytes: :grin:
BlaiseEbuth: If you'd like to write it, why do you wonder about people needs? Just write it.
MSmits: but the article thing was also on my list. I was gonna do uttt, but I prefer sharing things that I came up with myself and uttt would just be a compendium of stuff most longtime players know
MSmits: BlaiseEbuth i like it more if it's also used
Astrobytes: UTTT would still be useful, would save a *lot* of chat time
MSmits: very true
michaellan: your enthusiasm has piqued my interest for it
michaellan: (oware)
michaellan: yeah, i'm probably part of the problem for UTTT and wasting chat time
MSmits: I'm not even sure i like the game oware per sé, i just like that it is simple and that you have a lot of options to do things with it
MSmits: like it's relatively easy to do NN. You can write an eval for it and try mcts + eval, you can try opening books and endgame books etc.
michaellan: how does an opening/endgame book work in a bot
michaellan: does the bot say, "hey that looks like X position, switching to book moves"
MSmits: there's many ways to do it
MSmits: i like to use endgame books as part of the search
MSmits: so you go down the tree and if the state is simple enough, you do a lookup and solve that ndoe
MSmits: node
MSmits: in oware, my bot does a look up if the number of seeds goes below 10
MSmits: sometimes that means perfect play for half the game
MSmits: and sometimes it's useless
MSmits: storing it can also be done in various ways. In Bandas i have a long string hardcoded. In oware, i generate the endgame book in half a second so it's not a string in the source code
MSmits: thats what I'm going to share
MSmits: nn guys should like that it doesnt take much codesize, except the function itself
MSmits: I'll pseudocode it, but should be easy enough
michaellan: i am getting closer to gettin c4 gworking
Endless_void: i cant code
Endless_void: how do i learn
RightHandElf: I just got notified that my Coder Strike Back bot is moving up to silver league when it's been days since I did anything with it
Endless_void: wwwwwwwww
michaellan: thats awesome RightHandElf
michaellan: nothing better than free cash
michaellan: YES MY THING WORKS
michaellan: okay time to add pie rule and test in arena :)
michaellan: well i take that back: working for your level-up is better than not working for it
michaellan: the dumb boilerplate for the CG input is taking a awhile to write
The_wolf_of_the_silicon_valley: lmao
The_wolf_of_the_silicon_valley: hello guys
michaellan: hi
Wontonimo: hi
Wontonimo: it's late here
michaellan: hi wontonim o
michaellan: I think I'm pretty close
michaellan: (this time for real)
Wontonimo: to what?
Wontonimo: what are you close to?
Wontonimo: C4 ?
Wontonimo: i see you have a bot running on c4 right now
michaellan: yeah its buggy when i'm second
michaellan: but i'm gonna fix it
michaellan: also how can you tell I have a bot on c4?
Wontonimo: why's that? does it mess up on steal?
michaellan: No, not steal. just plain second
michaellan: steal is actually pretty simple logic for me
michaellan: just swap the root player
michaellan: (i think, right?)
Wontonimo: https://www.codingame.com/multiplayer/bot-programming/connect-4/leaderboard?column=SCORE&value=INPROGRESS
Wontonimo: showed that your bot was running
michaellan: ah
michaellan: well i can feel it in my clutches
michaellan: its so close
Wontonimo: i don't just lurk there, but went on a hunch. (more like i read the chat history and saw you talk about C4)
Wontonimo: I have 264 lines of code just dedicated to unit testing my C4 simulation (not including the unit tests for MCTS)
michaellan: wow
michaellan: i'm too ignorant to write tests
Wontonimo: my C4 simulation is only 118 lines
Wontonimo: so, 392 lines in total
Wontonimo: 382 ... math
Wontonimo: I was having some weird bugs that i couldn't figure out from replays
Wontonimo: also, i didn't trust my bitmask logic
Wontonimo: and good thing i did because it messed up on shifting right
michaellan: i'm currently losing to a guy who stacks them all up in one column
Wontonimo: yeah, i saw 1 replay like that
Wontonimo: https://www.codingame.com/replay/576232716
Wontonimo: pretty clever winning strategy :D
michaellan: the numbering is really annoying
michaellan: i hate the way its numbered
michaellan: so annoying, i repeat
michaellan: makes zero sense
michaellan: so overcomplicatred
Wontonimo: what numbering ?
michaellan: wait a sec
michaellan: the 0 and 1
AspectCodin: hola
michaellan: I'm breaking my code
Wontonimo: hello AspectCodin
michaellan:
Wontonimo: we are talking about the multi bot battle Connect 4 https://www.codingame.com/multiplayer/bot-programming/connect-4
michaellan: I would have a working bot if not for this stupid
michaellan: this is literally horrible for my cognitive effort
michaellan: because in my game I do not track, at all, who is "me" and who is "opponent" really
michaellan: but I still arbitrarily use 0 and 1 to alternate
michaellan: I Hate THis
michaellan: WEO:IFWJEJF:IOWEJF
Wontonimo: ;(
michaellan: how many times can we submit a day?
Wontonimo: i've never run into the limit
Wontonimo: but i don't usually submit again unless it has run at least half way through the previous run
Wontonimo: and i don't use a bot for submitting
michaellan: what do you mean by "run at least half way through the previous run"
Wontonimo: like, "send to arena" then not wait for it to finish in the arena and send another version
Wontonimo: has anyone shared this with you https://gekomad.github.io/Cinnamon/BitboardCalculator/
Wontonimo: struct shared it with me ages ago
michaellan: ah
Wontonimo: i haven't used it, but it may be helpful
michaellan: i meant like using "Play again"
michaellan: not submitting to arena
Wontonimo: i haven't hit a limit on that either.
michaellan: aight, thanks
Wontonimo: but i do a lot of coding locally
Wontonimo: i was just working on "lucky number" puzzle yesterday and was submitting like mad. Nothing bad happened
Wontonimo: are you running into a warning message about too much usage?
michaellan: no
michaellan: I just hate my life
michaellan: WOW
michaellan: i think i may have fixed it
michaellan: if so, that was on accident
michaellan: YES
michaellan: when i play my bot against myself it takes 53 moves to end the game, i think this is good news
michaellan: i can feel dopamine already
michaellan: (and first player wins)
michaellan: I havent tried to steal yet
michaellan: Haven't lost a battle yet in arena ;)
michaellan: I think i did it
michaellan: oh my god
michaellan: oho
michaellan: and i did it even pumping out tones of debug output
Wontonimo: oh yeah, it's going!
Wontonimo: haha ... it's destroying wood 2
michaellan: I'm probably gonna crumble in wood 1 ... :(
michaellan: I need to implement STEAL for myself xD
Wontonimo: you are beating the boss by 6 points
Wontonimo: that's great
michaellan: I HAVENT LOST A SINGLE MATCH YET
michaellan: lets hope it stays that way
Wontonimo: yeah, implementing steal with an already working bot isn't gonna be hard
michaellan: yeah, it seems i just hardcode move 1
michaellan: but
michaellan: my entier program is SUPER shaky
michaellan: i could touch something and break the entire thing
Wontonimo: why so shaky?
michaellan: because I am xoring by one everywhere
michaellan: it is like the equivalent of the classic MCTS "do I negate here or not"
michaellan: xoring the "current/root player" by 1
michaellan: ohmygod ohmygod
michaellan: i think i might get a perfect run, no losses
michaellan: this feels so good
michaellan: i wrote win detection with the masks
michaellan: and i never actually tested it
michaellan: it seems like it works :rofl:
Wontonimo: nice, very nice
Wontonimo: you went from nearly jumping out a window to dancing in about 28 minutes
michaellan: HAHA
michaellan: do you use masks or int128s for win detection?
michaellan: i heard MSmit s uses some super duper weird method
michaellan: of not playing losing moves
michaellan: idk how that works in practice/implementation
Wontonimo: 64bit with masks
michaellan: yeah but how do you guard against losing positions
Wontonimo: you are in wood 1 i see
xxd: :)
Wontonimo: hmm, i feel competition coming my way
xxd: Apparently my STEAL deteection is buggy
xxd: so i'm losing those games dumbly
xxd: currently 59th... climbing towards you ;)
xxd: i'm probably gonna drop back down due to my bug
Wontonimo: in the higher leagues everyone starts with a fair move anyway, so if you get there you can actually skip steal but they will steal from you
xxd: yeah, they're stealing mine and my program just goes crazy
Wontonimo: oh, because you can't account for someone else stealing
xxd: its hard because since the nodes are reused
xxd: i have to like
cheesecake_assassin: Hey
