martinpapa69: 281474993527863 thats a big number

martinpapa69: careful with the owerflow

martinpapa69: v

Default avatar.png will.claude: Trying this site out for the first time, used to doing stuff like Codewars/leetcode, feels a bit different

jacek: amazons puzzle of the week :tada:

xxd: @martinpapa69, yeah, we figured it out, it was uninitialized. it's odd because I could've sworn struct members get default initialized to the "0" value...

akashhuyaar: how to understand that ai of coders strike back game i can't understand the problem exactly fr

xxd: Do you have a question about the rules or are you asking how their bot AI works

akashhuyaar: how it works

Uljahn: you mean under the hood? you send the bot code, it gets executed, then you receive JSON replay back to be shown in the browser visualizer

Uljahn: also there is a game engine (a referee) which generates inputs for bots depending on its outputs, so your task is to write a program which reads inputs and outputs some commands

Uljahn: you should implement some logic to make these commands sensible, that is called AI

Default avatar.png Hmode: system out println ("1");

Default avatar.png Hmode: thats all i did!!!!!!

akashhuyaar: ohhh cool @Uljahn

OldJohn: @martinpapa69 What are you testing, you were so much more successfull last week ?

Default avatar.png [-8-]pro[-8-]: how do i close the chat?

OldJohn: Litlle arrow just at he bottom of the chat

Default avatar.png Artycoka: right next to the little "gear"

martinpapa69: i worked on quantized nn inference last week. still buggy i think. or just bad parameters

OldJohn: quantized ?

Uljahn: is it QAT or post-processing?

OldJohn: Do you have a reference ?

martinpapa69: qat. i train ith tflite

martinpapa69: https://blog.tensorflow.org/2020/04/quantization-aware-training-with-tensorflow-model-optimization-toolkit.html

OldJohn: Ok thanks I 'll take a look even if I am using pytorch :-)

martinpapa69: did you add some smart stuff to your bot or just lucky parameters?

OldJohn: Mostly optimization

martinpapa69: how many rollouts do you have in 50ms ?

OldJohn: more than 9000 in the opening

OldJohn: up to 50000 in the ending

martinpapa69: nice. 4k at start here

martinpapa69: nn size? i have 128->64

OldJohn: actually the first layer here is 88 :-)

derjack: oh my

martinpapa69: the input layer 88 ?

martinpapa69: or the first dense

OldJohn: Input 291

martinpapa69: ok

martinpapa69: ye my nn might be a bit too big. but it worked with the float version

OldJohn: But the input is sparse so the matrix vector can be optimized

derjack: yay for one hots

martinpapa69: ye, i have precalct the input*first_layer

martinpapa69: as the input is always 1.0

OldJohn: Exactly

OldJohn: the matrix vector is then very optimized (that is my main job in real life)

OldJohn: Even if normally I use the mkl library

martinpapa69: nice. I too have avx matrix multiplication. but for some reason its not much faster than my float one

OldJohn: It should be, you can use Intel oneapi tools to understand why it is not

OldJohn: I was so surprised o how bad compilers are on dotproduct

OldJohn: and if the size of the matrix is big, blockind may be necessary

OldJohn: Even for matrix/vector

martinpapa69: no idea what is that

martinpapa69: i just copied my code from here

martinpapa69: https://github.com/glinscott/nnue-pytorch/blob/master/docs/nnue.md

PeaceMoreZ: how do i see the correct answer after finishing a game?

PeaceMoreZ: "view code" option is not showing

RoboStac: if you mean clash of code then it's up to the other players if they share or not

PeaceMoreZ: oh ok

PeaceMoreZ: thanks

PeaceMoreZ: and yes it was in clash of code

PeaceMoreZ: An error occurred (#705): "You are not allowed to access to this solution".


Default avatar.png Izzy90: Hey - noob question here. Say I wanted to use a NN for a certain bot. How would I go about training it? Where and how would the model parameters be saved between training iterations, and after training is completed?

martinpapa69: if u want to learn how to make nn bots I'd recommend you to start with DQN

martinpapa69: https://pytorch.org/tutorials/intermediate/reinforcement_q_learning.html

Wontonimo: Izzy90, usually you do that offline

Wontonimo: by using 10,000's of games

Default avatar.png owenmelbz: just found this website, but confused as to what it's trying to do. Is it learning how to code games? or just learn code via gaming quizes?

just looking at the first coders strike back, and it's talking about figuring out "thrust" - is the challenge here how to code... or is the challenge here understanding like physics and maths?

AntiSquid: hey Automaton2000 what's up ?

Automaton2000: cant see it in the ide

Wontonimo: hey owenmelbz, there are several things on this site. The bot battles like coders strikes back are fun ways of seeing how you are able to code and problem solve compared to other people

Wontonimo: different bot battles have different problems, and not physics bases. Connect 4 and Ultimate Tic Tac Toe are examples of classic board games with no physics

Q12: Hey, does someone have a good algo for learning spells in the beginning of game in Fall Challenge 2020? this would help a lot

Hunter64TheOne: hello

Wontonimo: Q12 I haven't entered that game until just now

Wontonimo: what have you tried so far?

technoindiangamerg: hi

technoindiangamerg: 0x0x0x0x

Wontonimo: hi

Q12: learning the first spells in list to get opponent blue ingredients, learning the highest spell by value I can learn (the value for each ingrdient is his tear + 1)

Q12: creating cycles, which means that from each ingredient you have a spell to convert to each other ingredient

Q12: as much cycles as I can

Q12: all of those options have a limited number of learns

Q12: I am currently at rank 46 at gold, I desperately want to reach legend league

ProCoder03: Wait after the contest end , does our code and ranking disappears ??

Q12: no

ZarthaxX: nop

ProCoder03: I was in Bronze league in Fall Challenge

ProCoder03: Now I am in WOOD 2 again :crying:

ZarthaxX: impossible

ProCoder03: Yup !

ZarthaxX: cant be

ProCoder03: Then where is the ranking and my code :thinking:

ZarthaxX: contest history

ZarthaxX: https://www.codingame.com/contests/fall-challenge-2020

ProCoder03: Thanks

ZarthaxX: yw :)

KiwiTae: ZarthaxX o/ not working today?

ZarthaxX: hey kiwoo

ZarthaxX: yes im

ZarthaxX: but in 45 mins

ProCoder03: Aw shit!! I forgot That was another account

ZarthaxX: told you

ProCoder03: :sweat_smile:

Default avatar.png holite: ok i am going to leave the clash :(

raiz_rizon: wait a im

raiz_rizon: new to

Default avatar.png holite: of can you just answer for this

Default avatar.png holite: Mario is marching to the castle to save the princess. In the last phase he has to jump over a number of pillars of different heights. When Mario jumps from a lower pillar to a higher pillar, he has to use High Jump. When he jumps to a pillar of lower or same height, he has to use Low Jump. Your task is to find out how many High Jumps and Low Jumps Mario has to do.

Default avatar.png holite: quiet diificult :(

Default avatar.png holite: can you give the python or cpp code for this "raiz_rizon".

KiwiTae: aint hard though u just need to diff and count pos and neg in the array

Default avatar.png holite: ok gotcha

Default avatar.png holite: not if the array must have been not pos or neg you have to len it and and fine the the value of it using a for in range.

raiz_rizon: ok thank you

raiz_rizon: wait I ' am learning

xxd: looks nice

TobiasA: what rank in csb

TobiasA: ?

grygory: hello:)

grygory: im looking some codeing python friends?

grygory: mayby somebody want create any easy project?

grygory: i'm beginner

michaellan: Is there any real overhead to using std::array over raw C arrays in C++?

jacek: probably not

Default avatar.png Magnakay: Hi

Default avatar.png Upskiller: hi

Default avatar.png Upskiller: any idea about this fibonacci thing?

Default avatar.png Magnakay: You can look in youtube, there are a lot of videos with great explanation

KiwiTae: Upskiller fibonnacii thing?

michaellan: failing to convert my C++ MCTS into a bitboard-ed version :sad:

michaellan: its so finicky

Scarfield: have you tried bitboarding before?

jacek: struct left and he cant see that amazons is the potw :c

Scarfield: he left? :scream:

jacek: shore leave

Scarfield: he will be back, there are more hex games that needs to be made multies for

michaellan: @Scarfield, no, first time

Scarfield: ok, have you made a function to visualize the board? can really help finding errors :)

michaellan: yup

michaellan: i think its the MCTS part thats finicky

michaellan: one player keeps suiciding sorta

michaellan: (The other player wins normally)

Scarfield: which game?

michaellan: now what would be great is if i could visualize the tree as its growing...

michaellan: i'm just doing this on normal (not ultimate) tic tac toe on my own computer

Scarfield: how do you check if a game is won?

xxd: http://ix.io/3vug

xxd: code^

Scarfield: if you are doing it locally, you could see the tree grow, just limit the number of times the code is run or something like that

jacek: and the mcts works in normal board?

jacek: no sign errors?

xxd: that must be it, i changed the backpropagation code for no reason to try and optimize it

xxd: let me use my old working backprop code

Scarfield: no!

Scarfield: :p

jacek: oO

xxd: what do you guys use to increment

xxd: i think wontonimo does +2 for win, +1 for tie, and +0 for lose

jacek: normally is 1, 0, -1

xxd: ok

xxd: was just wondering how that would affect UCB1

Scarfield: i use 1, 0.5, 0. but remember to adjust the ucb so it "fits"

jacek: maybe not so bad, winning is highest, losing is lowest, but the range is changed

jacek: perhaps adjust exploration only

jacek: but after enough iterations it should converge even with crappy exploration

Dohmanlechx: Why doesn't C++ substr work as expected? I try to substr(16,20) for instance but still it returns a lot of letters...

xxd: second param is length

xxd: not end inde

xxd: s/inde/index

xxd: so you want substr(16, 4) ii think

jacek: c++ api :unamused:

Dohmanlechx: Lol!

Dohmanlechx: This is what I get when trying learn a new language, I guess. Thanks <3

Aina_Tiavina: Hello

Default avatar.png PMierzwa: is there any way to debug using breakpoints for c++?

darkhorse64: Not within the IDE

Default avatar.png PMierzwa: So i have to copy the code + the input to another editor

Default avatar.png PMierzwa: ?

jacek: eeyup

jacek: here, you can print to stderr at the most for 'debug'

Default avatar.png PMierzwa: ahh ok

Default avatar.png PMierzwa: ty

Default avatar.png PMierzwa: its a shame, since i am not trying to learn how to debug without the proper tools, but rather the new language

Default avatar.png PMierzwa: but ok

Default avatar.png PMierzwa: its possible to copy the stuff to another ide

Dohmanlechx: Thanks for the help about substr, managed to complete the ASCII Art now. You guys are welcome to review: https://www.codingame.com/training/easy/ascii-art/solution?id=20539508

jacek: :tada:

Default avatar.png gilroky: System.out.println("4"); // The index of the mountain to fire on.

jacek: :thinking:

xxd: hes just telling us a fact, don't overthink it

Scarfield: the descent solved

jacek: the ascent unsolved

yfe42: the solution descended

xxd: solved descent the

Default avatar.png Sacder: can someone help me with the temperatures

Astrobytes: bigger number == higher temperature, smaller number == lower temperature [solved]

BlaiseEbuth: Mods these days...

Astrobytes: :P

Astrobytes: "the temperatures" is a tad vague.

Default avatar.png Sacder: the one where it asks to find the value closest to 0

Default avatar.png Sacder: im new to python

xxd: so you want help with python

Default avatar.png Sacder: ye

xxd: not with the temperatures

Default avatar.png Sacder: basically

Scarfield: today you have the mod "emoji" blaise, chat is weird

Scarfield: Helpstrobytes

Scarfield: what have you tried so far sacder?

BlaiseEbuth: "emoji" ?

Scarfield: logo what ever, yesterday i couldnt see your mod tag

Astrobytes: Blindfield

FalINTOblivion0112: omg blaise is back to mod

FalINTOblivion0112: that is amazing

TobiasA: why?

Astrobytes: It's temporary.

FalINTOblivion0112: temp?

FalINTOblivion0112: thats even better

BlaiseEbuth: Is it ?

Astrobytes: afaik

Astrobytes: WAs cause of the chat reboot

Scarfield: so yesterday you werent a mod, but today you were resurected?

BlaiseEbuth: Yesterday I already was

xxd: light mode on codingame

Default avatar.png Sharkle: please no

xxd: its not very good right now

Default avatar.png Sharkle: i know

xxd: I use it

Default avatar.png Sharkle: scary

BlaiseEbuth: Well, unless they decide to fix their entire (weird) system, I'll be re-moded at each chat crash. So approximately once a week (unless they decide to fix the chat, but we know they won't)...

Scarfield: xD

Default avatar.png Sharkle: yo guys im not learning anything and im really confused

xxd: can someone give an example of how to encode unicode in C to make bash solutions shorter using system()?

Default avatar.png Sharkle: this game isnt explainging anything to me

xxd: the game wont teach you python

xxd: its expected you know python already

Default avatar.png Sharkle: oh ok thanks mate

xxd: the problem is pretty straightforward

xxd: if you have questions about the actual problem ask

Default avatar.png Sharkle: hmm ok im good for now

jacek: oh my

Scarfield: oh you

Westicles: xxd, try asking on #fr

MACKEYTH: https://www.codingame.com/training/easy/encryptiondecryption-software has me stumped on validator 2

Wontonimo: okay, i just tried it. I didn't have any issues

Wontonimo: did you pass all the test cases with a generic solution MACKEYTH ?

Dohmanlechx: Can someone give me a hint about how to calculate the step between turns for the Shadows of the Knight - Episode 1 puzzle game?

Dohmanlechx: I guess some kind of formula where I use the count of windows and the max jumps Batman is allowed to make

Wontonimo: how about just dividing the board given the U D L R

Wontonimo: you should be able to just divide the x axis in half and and the y axis in half every turn

Dohmanlechx: Thanks

MACKEYTH: @Wontonimo Yes, several different solutions actually

MACKEYTH: I'm breaking the key down with String.split(" ")

Wontonimo: yeah, i don't do that

Wontonimo: because it doesn't handle the " " between " " break

MACKEYTH: I also tried Scanner.read() ing 26 times. Both worked on the test cases.

Wontonimo: how are you handling the space with split(" ") ?

elderlybeginner: i have some issue with power and speed in fantastic bits

elderlybeginner: during throw, should I consider mass of the ball? e.g. ...

Wontonimo: are you doing a sim elderly?

Wontonimo: or just a if/else bot?

elderlybeginner: when wizzards goes 200, power of throw is 500, what will be the speed of the ball?

elderlybeginner: kind of evaluation. I'm trying to get proper throw angle, I tryied to calculate it basing on sine theorem, but I see that 500 + wizzard_speed cannot be taken as a ball speed after a throw

Wontonimo: that feels like something you could use stderr to print out when you recreate a similiar situation in the game, then make that a test case for yourself for reverse engineering the equation

Wontonimo: is the equation not in the problem statement of the game?

elderlybeginner: I have equation, thou it need ball/snaffle speed.

elderlybeginner: and e.g. wizzard is moving 343 when grabbing the ball (snaffle), slowing down (according to friction 0.75) to 257 when it's going to throw, but the ball gets the speed of almost 1500

elderlybeginner: ok, maybe it's power = 1/2 * (mass * velocity **2)

elderlybeginner: but that would be even less

Wontonimo: some game data would be valuable

Wontonimo: including the power of the throw,

Wontonimo: the next turn vx vy of the snaffle

elderlybeginner: http://chat.codingame.com/pastebin/77f3590b-ca21-4888-b9f0-900d71c2e332

elderlybeginner: http://chat.codingame.com/pastebin/6ff688d3-4376-481b-a27b-c3df47370d9c

elderlybeginner: https://www.codingame.com/replay/574876919

elderlybeginner: ah, links problem ;)

elderlybeginner: I'm looking for connection between: power, velocity and mass during the ball is thrown

Wontonimo: got a second data point?

Wontonimo: from this, all we can say is power 500 = 1463

Wontonimo: which, by the way is 1950*0.75

Wontonimo: so, for all we know the velocity is ( power*4 - 50 )*0.75

Wontonimo: or power * 3.9 * 0.75

Wontonimo: need another couple data points to rule out different equations

elderlybeginner: ok, counting

elderlybeginner: power 100: gives 531 power 200: gives 725 power 300: gives 924 I will need to throu it straight, as now there is an angle which can decrease maximal speed

Wontonimo: or also collect that data

elderlybeginner: power 400: gives 1094 power 500: gives 1318 as the throu is not perfectly in line of wizzard movement, speed of the ball is lower

elderlybeginner: i guess I have to throw it stright

Wontonimo: or not and just record all the data

Wontonimo: put it all into a spreadsheet

Wontonimo: including the speed of the thrower during the throw

RoboStac: if you've got the wizard thrust working it's exactly the same (other than half mass). When thrown it has the speed of the wizard and then gets a thrust of up to 500 in the direction thrown

Wontonimo: and the target throw

Dohmanlechx: Okay looks like medium puzzles are too hard for me yet, have to make more Easy ones...

Wontonimo: have you done all the easy ones Dohmanlechx?

Dohmanlechx: Nah only like 5 of them and jumped right away to Medium :P

Wontonimo: Have you tried https://www.codingame.com/training/easy/1000000000d-world Dohmanlechx ?

FalINTOblivion0112: well i solved three very hard puzzle

FalINTOblivion0112: thats nice

michaellan: nice

michaellan: which ones?

michaellan: i solved the ones that arguably didnt belong in Very Hard xD

Westicles: Mars 3, Resistance, and Recurring Decimals

michaellan: oh nice

michaellan: i solved resistance, unflood the world, and barnyard

BlaiseEbuth: Still one to do.

michaellan: which?

michaellan: what do you mean by that

BlaiseEbuth: A third very hard

xxd: ha

xxd: which one are you implying is not very hard?

BlaiseEbuth: You didn't understand me. I only did 2 very hard.

RaulButuc: lol

BlaiseEbuth: RaulButuc ?

RaulButuc: anyone got any idea which dates the fall challenge 2021 will cover?

RaulButuc: really looking forward to it but if it's going to match the same days as last year I wont be able to attend :(

BlaiseEbuth: Why lol so?

BlaiseEbuth: Nobody knows about the dates. We don't even know if this gonna be a bot programming challenge...

RaulButuc: the period before black friday is going to be super busy (contract with an ecommerce platform and its the busiest 2-3 weeks of the year)

RaulButuc: ah fair then

AllYourTrees: wait it might not be bot programming??

AllYourTrees: what else is there?

BlaiseEbuth: Escape thing...

RaulButuc: nice

RaulButuc: it'd be my first community event lol, hope i won't miss it

AllYourTrees: is a 4000 person clash of code possible? XD fastest mode incoming

AllYourTrees: over in 1 min

RaulButuc: wow, that'd be total chaos :)

xxd: What if it's a code golf challengee

BlaiseEbuth: Server will be dead after 10 seconds.

RaulButuc: haha, very likely

xxd: hmm... if it is escape that will be disappointing

xxd: my impression of the tutorial was not the greatest

Westicles: All the complaining will be awesome though

michaellan: how do leagues work in a live challenge?

BlaiseEbuth: At start only bronze is open. After a few days the bot of a player is chosen as the boss, and silver open. And so one for next leagues.

BlaiseEbuth: *on

michaellan: I see, thank you
