Westicles: littlebear, still need help?
Westicles: oh, never mind wrong guy :P
littlebear: haha
Kilimandaros: Hi, after doing some puzzle I wanted to check 'best solutions for this puzzle'. It asks to choose prefered solution, but I can't see code - only top part is somewhat visible, but not even whole characters but more like parts of them. https://ibb.co/bFrnBPY this is how it looks. Any ideas?
littlebear: it says
littlebear: opps sorry
Westicles: which puzzle and language?
Kilimandaros: defibrillators and python3
Kilimandaros: but it also happens with other puzzles
Westicles: yeah, looks the same for me. you can click skip the review at the bottom
Westicles: there's a bug report think on discord, or you can post it to the forum
Kilimandaros: Ok, thanks.
ImAFkngNinja: how do you determine the number closest to zero? This is my problem
Write a program that prints the temperature closest to 0 among input data. If two numbers are equally close to zero, positive integer has to be considered closest to zero (for instance, if the temperatures are -5 and 5, then display 5).
C26_1: um, maybe I just use this program:
abs(min(Array))
Where Array is a Array of temperature
C26_1: print(abs(min(Array)))
littlebear: https://ibb.co/bHhC2Cr
C26_1: if there are two numbers, like -5 and 5 then the minimum of array is -5 and absolute of -5 is 5, hence the desire output we want
littlebear: answer is one of blue or orange, find it :p
littlebear: red dot is zero
BlaiseEbuth: And if there's -7 -5 and 5 C26_1 :3
C26_1: Um wait
C26_1: My program doesn't when the Array have negative numbers as the closest number to 0
C26_1: doesn't work*
C26_1: For example: -1, -2, 3, 7, -12. My program will output 1 becuase I use the abs function before print it, even though it should be -1
BlaiseEbuth: Anyway, giving/sharing solutions is not the CG policy.
Westicles: perhaps some sort of barter can be arranged
BlaiseEbuth: Oh. Hadn't seen... A server reboot and I'm back. :imp:
BoldGhost_9bff: is there anyway to view all the puzzles I have completed?
littlebear: yes
littlebear: go to puzzles easy medium hard, at bottom you can see i think
Maxim251: I have mathematical problem
Maxim251: http://chat.codingame.com/pastebin/3fc2b4fe-e6f3-462b-957f-e8b5ad498319
Maxim251: how I can write smart code to choice what hero is the best?
BoldGhost_9bff: thank you
ProCoder03: Compare there units, Maxim251
ProCoder03: make them public
ProCoder03: and have a class which compares there physique and arrange them
Maxim251: Bu how compare many different abilities?
ProCoder03: get a all there value into array with a specific order
ProCoder03: and check for minimum and eliminate them in all other array
ProCoder03: You need to have an array for each physique
ProCoder03: That's what I can think of for now...
Maxim251: I was thinking about using average. First add all values from specific ability, then devide by amount of heroes, and then take that average and check how many heroes have more points from average
ProCoder03: That's better mine
Maxim251: Then i need to do something like sort list.
Maxim251: Or maybe add all points togheter for one heroe, and then make sort list and compare who have the highest sum points?
ProCoder03: That's a bad one
ProCoder03: you need a overall good heros
Maxim251: Because I dont want eliminate heroe, who range is lower, but attack is higher
Maxim251: Yes, heroe who is the best in all situations
ProCoder03: or create your own formulae linking all the stats and calculate
Maxim251: Because at the beginning of game I dont know who will fit the best to fight with enemy heroe, and thats why I am looking for some method to choice the best hero
ProCoder03: Or better, use weightage like what you want more in your hero
ProCoder03: and calculate a overall score and choose the one with the best..
Maxim251: then Health, demage, move_speed, range
Maxim251: I think this 4 is important
ProCoder03: Find some percentage for wieghtage like 30 for health, 30 for damage and so..
ProCoder03: *weightage
Maxim251: I calculated by hand, that average for health of all heroes is 1201 points, that means that I need look for heroes who have more points then that average
Maxim251: Oww... o knw what You mean
ProCoder03: wdym "o knw what You mean"???
Maxim251: sorry, spelling
Uljahn: another method of choice could be parsing top players' replays to gather some statistics
ProCoder03: what is this puzzle btw ??
Uljahn: guess it's Botters of the galaxy multi
Maxim251: Yes
ProCoder03: thanks..

sirsatan: hey i cant find information about logic between lists in python.
sirsatan: e.g. how to interpret 'list and list or int'
sirsatan: no idea how type it in google to get some useful info ;/
Uljahn: you mean casting a list to boolean?
Uljahn: empty list is False, not empty is True
sirsatan: not exactly, list consist ints
Uljahn: ok, i'll DM you
sirsatan: thanks
smacker01: how can i get output so it won't interrupt test cases?
Uljahn: use debug output
smacker01: where can i put print so it will go to debug and not to actual output?
ash15khng: the comments in the pregenerated code should help
smacker01: oh thanks

littlebear: :rolling_eyes:
Hv11: Anyone know the best way to learn coding here?
johnWickkkkk: yes
rkocharyan: just read books
rkocharyan: start with c++ probably
johnWickkkkk: by practicing instead of posting this ques
rkocharyan: because it's the hardest oone
SteindelSE: Two of the worst pieces of advice I have ever heard "read books and start with c++".
johnWickkkkk: haha
rkocharyan: why?
SteindelSE: Reading books is good, but you need someone to explain it to you in a practical way @Hv11
SteindelSE: I would recommend a programming class if you're still in high school, whether at the school itself or in a learning annex/votech of some sort.
SteindelSE: Ask teachers, they want to see you succeed and will get you information.
rkocharyan: if he doesnt have someone to explain him it's still better to read books instead of watching hOW tO LeARn C++ in 1 HoUr videos
rkocharyan: if will take extra work to learn c++, but he will actually understand all programming concepts
SteindelSE: If you're past high school, you can either seek out a college education, or if you're looking to get your feet wet, seek out something significantly cheaper like a Udemy into course. It will allow the instructor to explain it to you in a practical way AND have a chat where you can discuss the coursework with the instructor, their helpers, and other people taking the course.
SteindelSE: Udemy intro* course
rkocharyan: It's your opinion but I would never pay someone to teach me programming
Hv11: Ok
SteindelSE: You can definitely do it for free using youtube and books, but have someone on hand, even a community, that backs the language you're learning
SteindelSE: I would learn something like python where you have to worry less about formatting and syntax and more about understanding how the code works'
SteindelSE: Get yourself an understanding of data types, variables, conditional and incremental operators, modulo. Then move on to refactoring code into functions and understanding how functions work with parameter in and returns out.
SteindelSE: Finally get into Object Oriented Programming. Start developing an understanding of classes, how they are blueprints for objects and really almost everything that isn't a primitive data type is an object in most OOP languages.
StevenV: Hello guys?
SteindelSE: After that you've scratched the surface and still need to learn about polymorphism and encapsulation, but those are good starting points above, respectively.
StevenV: actually, I see this platform as a place to learn about AI more than to learn a programming language
SteindelSE: If you do go with python, and I recommend it, here's the official python discord https://discord.gg/python
SteindelSE: Good luck @Hv11
StevenV: why you don't like c++
StevenV: SteindelSE
SteindelSE: I love C++ ?
StevenV: it is good, especially you can learn about pointer, memory
SteindelSE: Where you trying to ask why don't I like C++ as a starting language?
SteindelSE: Were*
StevenV: yes
StevenV: I start with c++
StevenV: then later I jump to other languages and everything is a piece of cake then
ProCoder03: My 2 cents would be start with C
ProCoder03: learn to code each and every function first..
SteindelSE: It's cryptic. For someone who doesn't even understand what a variable is yet, you're adding unnecessary difficulty to the education. To understand the fundamentals of programming, the best approach for most people is to focus on understanding the fundamentals, not why you need to include a library, why this thing needs {} and that one does not... etc
StevenV: I skip c and go directly with c++
StevenV: well I just realize that this platform doesn't have Lips
StevenV: *Lisp
SteindelSE: Lisp has lost its fame and started its journey to death unfortunately.
ProCoder03: Lisp went into hiding many years ago and have just started to reappear now...
StevenV: we have Clojure
SteindelSE: Clojure, Python, Java...
StevenV: I think I will try on that though
SteindelSE: I've settled on finishing my bachelor in C# (although I know several other languages) because, to put it way too simply, it's basically better Java now that cross-platform has really taken off. Any popular language is a good language to learn, someone will always want you for something.
MiyamuraIzumi: C# and Java are quite the same
SteindelSE: Agreed.
SteindelSE: With the documentation on hand, it's quite effortless for me to write something in Java as well
MiyamuraIzumi: I will learn Rust if I have time though
SteindelSE: Rust is very popular, not a bad choice
ProCoder03: after C lang and its derivatives stink, I find Rust a bit rusty to learn..
MiyamuraIzumi: I learn for the interesting purpose
SteindelSE: Couldn't comment. I have looked at exactly 0 lines of rust code. Just hasn't come up for me.
ProCoder03: is looks more like fp to me..
StevenV: what is fp?
StevenV: functional programming?
ProCoder03: yup
StevenV: I don't know Rust, but I don't think Rust is functional
ProCoder03: ikt, but the syntax seems to be borrowed from fp
ProCoder03: like u use 'let' to declare rust
StevenV: oh
ProCoder03: for anyone who wants to learn rust https://github.com/rust-lang/rustlings
ProCoder03: sorry had to dig for it..
MiyamuraIzumi: :D
Rich_Engler: NAh, Start with Assembly
littlebear: binary
MiyamuraIzumi: :(
MiyamuraIzumi: do you know knuth books?
Rich_Engler: If you can figure out assembly, you can figure out almost any language
MiyamuraIzumi: if you want to learn Assembly, then they are for you
MiyamuraIzumi: Assembly is for compiler writer
MiyamuraIzumi: not for me
Rich_Engler: Are any of you here familiar with the codex of alchemy flash game?

MiyamuraIzumi: this platform is for solving problems
goggels: a person that likes somone online
MiyamuraIzumi: why don't you find some problem to solve?
goggels: like what?
MiyamuraIzumi: csb
goggels: wazzat
MiyamuraIzumi: you know, if you could reach legend once, you'll addict to those game
MACKEYTH: What do you think is the easiest bot programming challenge to reach legendary in?
PatrickMcGinnisII: Tron
PatrickMcGinnisII: Coders Strike Back is easy gold
goggels: hi!
MACKEYTH: CSB should unlock multiple bikes in bronze, I think.
MiyamuraIzumi: gold will unlock 2 pods
PatrickMcGinnisII: CoIF and GitC are the most fun imo
MACKEYTH: It's kinda frustrating to put all that effort into building a solid racer for silver and bronze then get the rug pulled out from under you
PatrickMcGinnisII: kinda why OOP was invented tho
MiyamuraIzumi: what is CoIF and GitC?
goggels: hiiiiiiyyyyyy
PatrickMcGinnisII: Code of Ice and Fire, Ghost in the Cell
PatrickMcGinnisII: Fantastic Bits has some gitc codde that can help you understand multi-agents
MiyamuraIzumi: Fall Challenge 2020 is the one bring me here, I will reach legend on it once day
PatrickMcGinnisII: that was fun, but hard ... alot of new competition began with that one
MiyamuraIzumi: alot of new competition began?
MiyamuraIzumi: what do you mean
PatrickMcGinnisII: alot of new players, especially from japan
MACKEYTH: I just redid my fall 2020 bot and got from bronze to silver.
MiyamuraIzumi: CG has spring 2020 and many more
MiyamuraIzumi: ah
MiyamuraIzumi: new players
MACKEYTH: Having trouble getting it to consistently not time out. Java.
MiyamuraIzumi: I first use Java on it
MiyamuraIzumi: but seems that performance is important
PatrickMcGinnisII: cg won't let me play a round of FC2020 with MiyamuraIzumi...same league...but i think you gotta be just a little higher on the leaderboard
MiyamuraIzumi: my current bot is half bfs
MACKEYTH: Should let you choose anyone in your league as an opponent in the IDE
PatrickMcGinnisII: only top 999
PatrickMcGinnisII: i think
RoboStac: theres a cap of top 1000 because csb used to often crash the browser with the massive leagues
MACKEYTH: Oh really? Didn't know that.
struct: robo seems like a nice improvement
RoboStac: or just take forever
struct: from your old bt bot
RoboStac: yeah, just need to stop losing randomly to people outside the top 2
MACKEYTH: Does anyone know a better timing mechanism in Java than currentTimeMillis?
MACKEYTH: I feel like I get inconsistent results from it.
PatrickMcGinnisII: MACKEYTH think your stuck with millis
struct: maybe you start the timer in the wrong place
struct: you must start the timer after reading the first input
goggels: hihihihihih
Uljahn: goggels: pls stop spamming, im warning you, next time is ban
MACKEYTH: I've been reading round start time immediately after my first input statement. Should I be doing it somewhere else?
MiyamuraIzumi: actually, I my code got timeout randomly if I check end time too near the limit
RoboStac: I seem to remember some java people saying there was a nanosecond one that was better due to being monotonic?
MACKEYTH: I'll have to check that out.
PatrickMcGinnisII: it's still just a long
struct: google return System.nanoTime()
RoboStac: yeah, but you don't need more precision you need stability (eg steady_clock vs high_resolution_clock in c++ it's much better to use steady)
RoboStac: on here
MiyamuraIzumi: I really wonder how can someone use Java to solve problem using AI algorithm
MiyamuraIzumi: its performance is too bad
MACKEYTH: I've got my FC 2020 bot choked down to 20 ms. Anything more that that and I start running into timeouts.
RoboStac: hmm, that sounds like a bigger problem then
struct: maybe gc kicks in
MACKEYTH: gc?
struct: garbage collector
MACKEYTH: Yeah, could be.
struct: but even then it should not take that much time
struct: imo
struct: but im not really familiar with java
PatrickMcGinnisII: MiyamuraIzumi anyone's java bot can beat any of my PHP bots, so .. no excuses
MACKEYTH: Legendary #9 in FC2020 is in Java. It's not hopeless. I just need some more finesse, I guess.
MiyamuraIzumi: yeah wala solve most problem with Java
**PatrickMcGinnisII loves making excuses
MiyamuraIzumi: but we have to know what he's done
MiyamuraIzumi: those Java code is quite mistery
MACKEYTH: Maybe I could get a performance boost if I change over some collections framework stuff to arrays?
PatrickMcGinnisII: hmm, yes it seems nanotime helps in a linux system from clock drift... but I would be more concerned with how many times you check the time
MiyamuraIzumi: I am a Java developer, so really I do want to know how they do that
MACKEYTH: Lots of C++ in the legend league...
struct: well in c++ you have full control
MiyamuraIzumi: C++ has big advantage
struct: But anyone can learn it
struct: I don't feel like its an harder language to learn
MACKEYTH: PatrickMcGinnisII I'm checking once at the head of my BFS loop.
MiyamuraIzumi: I know C++, but I really do want to know more on Java
PatrickMcGinnisII: Lot of times higher library constructs generally take alot more time... sometimes you just have to KISS - keep it simple
goggels: i wanna friend
goggels: oh and hi
wala: MACKEYTH this post mights help you https://www.codingame.com/forum/t/java-codingame-tips/191870
PatrickMcGinnisII: Some games i can get a depth 5 tree, others only 2. HMM, let's see looks like I'm only doing depth 2 in FC2020 with like 30 nodes after it's trimmed, the rest is timing heuristics
goggels: can someone be my frnd
PatrickMcGinnisII: go play roblox
PatrickMcGinnisII: oh i use a pth finder to each recipe
PatrickMcGinnisII: hmm
PatrickMcGinnisII: could be better

goggels: im 10
goggels: how old are you?
MiyamuraIzumi: thanks wala, I bookmarked your post. I have to sleep now :D
wala: you're welcome
goggels: hello?
sonic.exe: i suck at this
goggels: hi and me to
goggels: how old are you
Uljahn: goggels: stop flooding
TimothyAlexisVass: hello

TimothyAlexisVass: What is the shortest way to get 1 integer input in Ruby?
Rich_Engler: Can you try making a code challenge even if you don't know a dozen languages?
Uljahn: for what purpose? you can try but don't expect it to be approved
TimothyAlexisVass: Why is this:
puts (gets.to_i/4).round()
TimothyAlexisVass: giving a different result than this:
print(round(int(input())/4))
??
TimothyAlexisVass: (Ruby and Python)
Uljahn: https://stackoverflow.com/questions/15735454/why-is-rubys-floatround-behavior-different-than-pythons

PatrickMcGinnisII: new puzzle sweet spot was fun
PatrickMcGinnisII: ok, to actual work then...glhf
Frothbile: This Dungeons and Maps puzzle is kicking my butt :disappointed:
AmazingPro: hahah
AmazingPro: nice
MACKEYTH: Sounds like fun, in the Dwarf Fortress sense
LeonPrefix: hi
vaaniicx: hi
Wontonimo: Hi new people :wave:
Wontonimo: there is more here than just clash of code, like puzzles and bot battles
goggels: um hi
goggels: Uljahn you shut up
Wontonimo: be nice, keep the talk code or codingame related, and generally stay on topic
goggels: ok imsrry
goggels: i need help
struct: goggels you have been trolling for long enough
goggels: umm ok?
AllYourTrees: sleggog
goggels: what does trolling mean
AllYourTrees: is Space Shooter's code available anywhere
Wontonimo: https://www.codingame.com/contribute/view/6870921d7302d6decba319f66b7716afddb3
Wontonimo: click download
AllYourTrees: ty
goggels: hi
goggels: iy
senku_yt: ok
Rich_Engler: I'm working on the temperatures puzzle, but can't figure out why the edgecase 12 always fails
Rich_Engler: Even after searching online for the answer I admit
Poostang: is there a way to start back in wood league?
JBM: nope
Poostang: gg
JBM: you're better than that
Poostang: well its ultimate tic tac toe now i have the big board but still dont have good small board bot
JBM: but why would you care?
JBM: the game isn't to be god a the small board
JBM: *good (but hey why not)
Poostang: still figuring out my minimax function
Poostang: and storing board in bits vs table
Poostang: its okay ill do the big board hopefully its not too crazy
struct: Poostang what I did was make it localy
struct: So i made the TTT version first
struct: I implemented both minimax and mcts
Poostang: hmm thats a good idea
struct: its a bit overkill but its a good way to learn
struct: so it was bitboards + miniminax + mcts
Poostang: nice
Poostang: ill try that thanks
struct: also the normal ttt board can be reused in the uttt versio
struct: you will have in total 10 of the ttt boards
AllYourTrees: has anyone done kaggle competitions?
Wontonimo: I started one. does that count?
AllYourTrees: hah yeah which one
AllYourTrees: how was your experience with it
Wontonimo: it's been a more than a little while, so I don't remember even. I also did a few competitions after their official deadline, so it's all kinda mixed. The platform was alright at the time and I remember getting caught up in trying to win instead of learn
Wontonimo: at the time it was just the start of people learning that they can hack the test set and get 100% or whatever perfect was with only a reasonable number of submits
Wontonimo: so the top of the leaderboard was very misleading until the very end with the final holdout data was used against the finalists
Wontonimo: I didn't get that far. it was a humbling experience to be sure
struct: i tried cf and found out i suck :p
AllYourTrees: whats cf?
struct: codeforces
AllYourTrees: wonton so would you say it was a lot different than CG?
struct: I think kaggle is more towards machine learning
AllYourTrees: https://www.kaggle.com/c/lux-ai-2021/overview/description
AllYourTrees: im looking at that ^
AllYourTrees: it seems like they started to support multiplayer games
struct: 3 months
struct: I only can code under pressure
struct: not for me
AllYourTrees: lol
AllYourTrees: ya what are CG competitions, 2 weeks?
AllYourTrees: or wait 1 week?
struct: yeah
struct: 10 days
AllYourTrees: :scream:
AllYourTrees: :wave:
struct: is that hi?
struct: sorry im confused :p
Wontonimo: hey AllYourTrees, yeah it is really different than CG in that it is very ML and DS focus
struct: But cant you write a normal ai though?
struct: im not sure ive never tried kaggle
Wontonimo: it's not like a game when i competed. It is more like opti, not multi
Wontonimo: no graphics. no interaction of your code with someone elses
struct: I see
struct: They changed it I guess
struct: https://www.kaggle.com/c/lux-ai-2021/leaderboard?dialog=episodes-episode-26832151
struct: Now I need to decide on what to do
struct: improve my bots or port a random game
Wontonimo: oh, that 's cool
Wontonimo: i guess they have changed
just_kenned: hi guys, how to improve logic? i dont winner no one :(
struct: But can you solve the problems?
just_kenned: not
just_kenned: dont make sense to me
struct: clashes?
struct: or puzzles?
just_kenned: clashes
struct: Some clashes can be a bit hard yeah
struct: If I were you I would start with puzzles first
ZaAinavolTrash: The Depression of the new.......
struct: CG official easy puzzles should be doable if you have programming knowledge
ZaAinavolTrash: nA
Wontonimo: to be able to do much here you need to know about loops, arrays, functions, and either math or data structures like trees in order to do more than the easy puzzles
just_kenned: thanks guys
just_kenned: :)
struct: also it takes time to learn
Wontonimo: strüct, are you thinking of using bitboards in tron, and if so how?
struct: hmm im not sure if ill do tron
Wontonimo: you did tron. you are in silver
struct: yes its a montecarlo
struct: :p
struct: I think
struct: yeap 4 years ago
struct: I still remember it
struct: bitboards are possible but im not sure if they are worth
struct: you will need 10 uint64_t * n_players
Wontonimo: i'm having trouble doing more than 12k evals (not rollouts), which is just way too low for MC
struct: how much depth?
Wontonimo: i mean for UCT
Wontonimo: currently i'm doing flat MC (not MCTS) with depth 5
Wontonimo: how many rollouts are you getting per frame?
struct: do you do uint8_t[20][30] to tstore the board?
Wontonimo: yeah
Wontonimo: int8_t ... oh
struct: its the same thing
struct: dont owrry
struct: worry*
Wontonimo: nvm ... i got confused. i used -1 and thought i botched it. i'm sleepy
YurkovAS: tron? easy legend with voronoi heuristik
Wontonimo: i'm using voronoi heuristic and i can't get there. what search?
YurkovAS: minimax depth 1
Wontonimo: crazy. what eval?
area - max(enemy_area) ?
struct: its hard to compare rollouts i only sim myself
struct: and it goes until it dies basicly
struct: I get like 50k per turn
pineapple_potatoe: hi
YurkovAS: eval by voronoi. without enemy play good 250place
struct: maybe I need to learn voronoi
struct: YurkovAS do you use avx in c4?
YurkovAS: struct yes, today find bag and performance improvements. but i'm need find best parameters now
struct: nice
struct: parameters?
YurkovAS: without smart rollouts
YurkovAS: ucb const
struct: ah
struct: I just write a random number :D
struct: I think the current one is like 0.85f
YurkovAS: don you use smart rollouts?
struct: I do smart rollouts yes
YurkovAS: can't find it: always play worst
struct: But mine isnt perfectly smart
struct: I check for losing moves on it
struct: But I dont check if a move can create a losing move
struct: Like I place a piece on 0
YurkovAS: only losing?
struct: if opponent plays on top of that piece he can win
YurkovAS: or win?
struct: Both
struct: I need both
struct: But some people check only losing moves
YurkovAS: with reduce performance
struct: no, the other losing moves is more expensive
struct: Because rollout will go for longer
struct: on turn 0 it goes from 28 average moves to 34-36 average
struct: so I check for winning moves if there is any that player wins
struct: if not i check for opponent winning moves
struct: if the opponent on next turn has 2 winning moves then i lost
struct: else I play a random move
struct: if opponent only has 1 winning move on next turn i play that move to block him
YurkovAS: thanks!
YurkovAS: i'm go to sleep, bye. i'm check it again
struct: np
struct: gn
Wontonimo: good nigh
struct: Also I have a quite large ammount of rollouts
struct: 3M+ / sec
struct: 3-3.6
Wontonimo: that's crazy town
struct: I think msmits has similar ammount
struct: sometimes ill look into the asm code
struct: Currently i only used google benchmark on c4
struct: But I still think performance is a trap
struct: you will lose a lot of time on it for little to no gain
Wontonimo: yeah, i hear ya.
struct: On some games people can have <10% of the performance and still their bot is way better
Wontonimo: a good eval is worth a lot of depth
struct: Yeap
struct: On breakthrough at the start I had like 5M rollouts with ept
struct: currently I have like 3-3.5M
struct: but the bot is better
struct: Because the eval is more expensive but better
struct: I also think my eval there is not that great
struct: The way I normalize the score is just awfull
struct: score = (pawns / 16 * 4 + attacked_cells / 32 * 3) / 7;
struct: stuff like that :p
struct: im not even sure if this is normalization
Wontonimo: that's a lot of hyper parameters
struct: 16 is the number of max pawns
struct: 32 is the max of attacked cells
struct: thats not bad
struct: I have 20 parameters * 2 * 2
struct: so 80
struct: lol
struct: But how can I normalize without being like this?
Wontonimo: http://chat.codingame.com/pastebin/6699c391-9ec7-4689-a975-29b5001964c8
Wontonimo: bah, pastebin'ed again
struct: But I want the pawns to have more weight than attacked_cells
struct: for example
Wontonimo: yeah, that's the beta_parameter
Wontonimo: it discounts the attacked_cells
Wontonimo: compared to the pawns
struct: I ee
struct: see*
struct: This makes it cleaner
Wontonimo: http://chat.codingame.com/pastebin/2bd5d8d8-86f2-4d5b-a571-d4b593d90762
Wontonimo: i obviously write like code a little too much
struct: https://i.imgur.com/npEdK1S.png
struct: :p
struct: censored because the chat is public
struct: dont want to ruin the game :p
Wontonimo: yeah, good call
struct: its a mess
struct: Ill fix this tomorrow or something
Wontonimo: all that, then ")/28"
Wontonimo: instead of *0.035714
Wontonimo: and if all the scores are /28, does it really mean anything?
struct: They will never add up to 28
struct: but it would be like 1 in terms of eval
Wontonimo: got it. you can address that when finding UCB_C
Wontonimo: because UCB_C is dependent on the eval range
struct: yeah
struct: maybe I can try a larger eval for this game
struct: instead of -1,1
struct: Also its never even above 0.5
struct: because i do this
struct: return (score_1 - score_0) * static_cast<float>((player << 1) - 1);
Wontonimo: is 0 "even odds"?
struct: what do you mean?
Westicles: can't they make a compiler flag that does all that for you?
Wontonimo: what's the range of the score now, 0.5 to -0.5 ?
struct: score_0 can be 0 to 1
struct: but since i subtract score_1
struct: it will be very close to 0
struct: so it probably creates problem on mcts
Wontonimo: what score is "predicting a tie" ?
struct: 0
struct: but there are no ties
struct: sorry
Wontonimo: right, i mean "predicting a very close game"
struct: i havent checked it tbh
struct: I dont feel like there are close games
Wontonimo: oh
struct: You can tell easily if you are going to win or not though
struct: at least as a human
Wontonimo: well, i can't figure out what YurkovA was saying about tron ;(
Westicles: These poor clash guys. I was watching a stream and they had two problems in a row involving derivatives, and half the guys were 13 and totally lost
Wontonimo: hey Westicles :wave:
struct: He was saying to do 1 depth minimax
Westicles: hey Wontonimo
struct: and then apply voronoi to eval
struct: you just do 1 move for your snake
struct: and then eval
struct: so 4 moves total
Wontonimo: oh man
struct: https://www.codingame.com/playgrounds/243/
struct: There is this playground
struct: If you dont know voronoi
Westicles: gotta bookmark this and try tron one of these days
Westicles: this chat
Wontonimo: so, they didn't know about slope?
Westicles: they were reverses so no clue at all
struct: math :(
Westicles: All the math nerds are going to pick apart my rings and groups one
struct: do you do codeforces Westicles?
struct: You seem to be good at math
Westicles: no, never looked at it
struct: ah ok
struct: Its competitive programming they give you like N exercises and you have T time to solve them
C26_1: http://chat.codingame.com/pastebin/886cb196-6e86-4198-ae85-ad391a0548e5
struct: what is this #o(1) stuff?
C26_1: Um, I assume that input is O(1) time complexity
C26_1: Wait a minute
C26_1: I've never learn about random modules so I never know exactly what O of make a random numbers is
Wontonimo: waiting 1 minute is O(1) time complexity
Wontonimo: a reasonable random number generator is O(1). Anything more is silly.
C26_1: @Wontonimo, thank you for you contribution
C26_1: your*
C26_1: The code I was pasted is make an array (List) that has all unique elements smaller or equal to max (Assume that the length of Array is no bigger than Max+1)
C26_1: Well this code maybe helpful if you want to feed the array into Sorting Algorithms
Westicles: C26_1, seems there are several Vietnamese guys here lately. Are you guys in the same class or something?
C26_1: Oh yes, I'm Vietnamese. I'm 8th grade student
C26_1: Um but those Vietnamese you talking to aren't belong or related tome
C26_1: to me*
BobTheBuilder888: hi im new
Westicles: Ah, got it
BobTheBuilder888: i dont understand how this gaame works
C26_1: @BobTheBuilder888, hello
BobTheBuilder888: @C26_1 Hi
Wontonimo: hey bob
BobTheBuilder888: hello
Wontonimo: which game are you having trouble with Bob?
BobTheBuilder888: none im just new i dont understand like anything here, except javascript.
C26_1: Do you see the quest map
Wontonimo: you can choose javascript as your programming language in the dropdown at the top of the IDE
BobTheBuilder888: yeah i done that
Wontonimo: this site is kinda hard if you are not already familiar with loops, functions, arrays, and associative arrays
BobTheBuilder888: im familiar with functions, loops and arrays. Ive came here because i wnated to learn associative arrays :D
struct: associative arrays are 2d arrays?
Wontonimo: a['bob'] = 'builder'
^^ that
struct: ah
struct: like a map
Wontonimo: exactly
Wontonimo: aka hash
C26_1: it feels like a dictionary or some things like struct in C
Wontonimo: aka dictionary
Wontonimo: everyone want's to give it their own name it seems: associative array, map, dictionary, hash
struct: I think i always called it map
struct: in both js and c++
BobTheBuilder888: im trying 'coders strike back' thing, any tips?
Wontonimo: yes
Wontonimo: aim at the checkpoint
Wontonimo: go full speed
BobTheBuilder888: ok
C26_1: Ah yes, struct is made to store multi infomation of a object. dictionary is made to look up a one-to-one correspondence, list store a lot of different things, set store unique things
Wontonimo: if you are close, slow down a bit
Wontonimo: if you are given your angle to the checkpoint, slow down if your angle is more than 90 or less than -90
Wontonimo: do all that, and i'll give you some more hints
BobTheBuilder888: Your target should be the X, Y position of the next checkpoint. Can you fix that in the code?
BobTheBuilder888: yeah i am pretty bad
Wontonimo: yes, if you look at the starting code it is aiming at y,y
Westicles: You should write up all the tiers of discovery from aiming at the checkpoint to... whatever it is re curse does
Wontonimo: just change that print
BobTheBuilder888: yeah i changed it
AYB: did any one played REVERSED LOOK-AND-SAY
AYB: ?? pls
Wontonimo: nope
Wontonimo: i haven't
AYB: thank you for your respond
AYB: i have already 80% done
AYB: but i didn't get it in the phase 5
AYB: 3
AYB: not 4
AYB: not 5
AYB: it seems to me not logice
Wontonimo: what's not logical about it?
BobTheBuilder888: yeah i think my thrust was too low or something thats why it didnt work.
BobTheBuilder888: thanks though
AYB: doesnt follow the pattern
AYB: i had to hardCode it lol
BobTheBuilder888: yeah can someone teach me how to make the thrust levels go up.......
AYB: the Expected is 2222122222
but if you look to this number you can extract from it this number 222222222
AYB: what is thrust ??
BobTheBuilder888: yeah can someone teach me how to make the thrust levels go up....... im using javascript btw
BobTheBuilder888: and what the right thrust is
struct: console.log(nextcheckpoint_x, nextcheckpoint_y, 100);
struct: the last number it the thrust
struct: I think for the first league 80 should owrk
struct: work*
BobTheBuilder888: ok i thought thats how you didnt but then i didnt
BobTheBuilder888: i thought it didnt but now i know i just had the wrong numbers
ProCoder03: Good Morning :smiley:
BobTheBuilder888: morning
ZaAinavolTrash: Depression... Its 6:41PM
BobTheBuilder888: rip
BobTheBuilder888: its about to be good afternoon for me
Wontonimo: crazy, it's as if this flat earth is curved or something
BobTheBuilder888: well...........
BobTheBuilder888: flat earther saying earth not flat?
BobTheBuilder888: yes i know bad grammer
struct: They are just good trolls
Wontonimo: "we flat earthers live all around the globe" - real quote from a flat earther
AYB: lol
struct: dont believe in a globe but believe in teleportation
ZaAinavolTrash: Technically the crust of the earth is flat, but wrapped around the core making it a planet..
BobTheBuilder888: r/whooosh topic be like
AYB: its all about "Technically" xd
ZaAinavolTrash: yEa
Wontonimo: speaking of whoosh, how is your pod racer doing Bob?
struct: yeap even the earth photos are flat
struct: how can a globe be real
BobTheBuilder888: oh im not doing it now
AYB: even wall watches are flat
AYB: so time is flat
BobTheBuilder888: i cant be bothered to figure out the thrust level
AYB: and earth also
BobTheBuilder888: its not 80..
Wontonimo: 100
Wontonimo: use 100
Wontonimo: it's the max
Wontonimo: go go go
ZaAinavolTrash: Nani-
struct: Fun fact earth was named by a flat earther
ProCoder03: till wood 2 its max 100//
Wontonimo: lol strüct !
struct: you dont have to type that u wontonim o
ZaAinavolTrash: wait if the earth is flat...
BobTheBuilder888: im pretty sure i tried 100, anyways im doing 'the descent' task.
ZaAinavolTrash: How would trees, and houses work-
BobTheBuilder888: im pretty sure i tried 100, anyways im doing 'the descent' task.
struct: no its the opposite
BobTheBuilder888: rip
struct: how can you make an house on a globe
BobTheBuilder888: i accidentally pressed up button
ZaAinavolTrash: Basically: "Game Logic"
BobTheBuilder888: this thing called gravity, it always puts you down.
ZaAinavolTrash: true
BobTheBuilder888: top 10 things you get taught in school that everybody knows about
BobTheBuilder888: 1. gravity
Wontonimo: 0. binary
Wontonimo: that's the complete list unless you didn't learn the 1st thing in that list
ZaAinavolTrash: 2. tax fraud and depression.
ProCoder03: Nope first they need to teach us to count from 0 and not 1
BobTheBuilder888: true
struct: you dont need 0 if you code in lua
ZaAinavolTrash: Ye
Wontonimo: 10 things : 0 binary , 1 gravity. Not 11 things ZaAinavolTrash
ZaAinavolTrash: I don't know how to code I'm just here to be here-
ProCoder03: Lua is an exception well...
BobTheBuilder888: i dont know how to code tha well im just mainly chatting-
ZaAinavolTrash: Found this website, you should check it out, something about stuff idk about-
ZaAinavolTrash: https://indreams.me/
ZaAinavolTrash: Well how depressing, everyone left.
BobTheBuilder888: im here
BobTheBuilder888: just not paying attention
BobTheBuilder888: playing my first game of clash of code, got any tips?
ZaAinavolTrash: uh
ZaAinavolTrash: I wish
ZaAinavolTrash: But I have no info on coding
BobTheBuilder888: sad
BobTheBuilder888: well ill try my best
ProCoder03: just do it in the language you know and take 15 whole mins if you want..
ZaAinavolTrash: Idk any of them lol
ZaAinavolTrash: I'm mostly gonna try learning Lua
ZaAinavolTrash: But idk where to start.

littlebear: in the puzzle of the week neighbours i understand the problem it will look like for a 3 x 4 grid : http://chat.codingame.com/pastebin/f4d98a79-e417-4004-ac24-578eda068238
littlebear: *if i understand
PatrickMcGinnisII: huh? hard puzzle neighbor sum grids?
littlebear: is it the number of cells that are in 8 directions and inside the grid ?
littlebear: oops
littlebear: noo Custom game of life
PatrickMcGinnisII: well that's how many cells you will have to look at and count
Kilimandaros: Hi, after doing some puzzle I wanted to check 'best solutions for this puzzle'. It asks to choose prefered solution, but I can't see code - only top part is somewhat visible, but not even whole characters but more like parts of them. https://ibb.co/bFrnBPY this is how it looks. Any ideas?
