FriendlyKh1: heyyy
TheOfficialVirus: i have no clue what im doing
Tien118: :)_
TheOfficialVirus: someone help me i have no clue what this is
Tien118: what?
Ayza: what's your problem?
TheOfficialVirus: i don't know how to code at all
Tien118: oh
Ayza: I don't think this is a great website for starting to code
TheOfficialVirus: i want to learn but it did not guide me
TheOfficialVirus: do you know a good site to learn?
Tien118: hmmmmmm
Tien118: idk
Ayza: which language have you decided to learn?
Ayza: maybe I can guide you to some videos
TheOfficialVirus: c++ but i don't know what that is
Ayza: you sure you wanna start with it?
Ayza: It's a bit discouraging as a beginner
TheOfficialVirus: i don't know what it is
AbrahamJLR: You could start in the Practice section with easy problems. https://www.codingame.com/training/easy
AryanTripathi: hello

_kebab_: Hi guys, http://chat.codingame.com/pastebin/9b44c84a-7d8b-483d-8cc6-29a826601f3c
_kebab_: One question:
_kebab_: I dont understant why in python:
_kebab_: this return a string
_kebab_: print(*[len(i) for i in input().split()])
_kebab_: Here what mean "*"?
Ayza: it's the unpacking operator
Ayza: you can read more about it here https://stackabuse.com/unpacking-in-python-beyond-parallel-assignment/
Ayza: a,b,c = [1,2,3] would be a=1, b=2, c=3
Ayza: a, *b = [1,2,3] would be a=1, b=[2,3]
_kebab_: Thanks, I will read it :+1
_kebab_: :thumbsup:
Ayza: np
Tanvir: I din't understang what nextCheckpointAngle is in Mad Pod Racing puzzle. if someone could provide a drawing of the angle on a screenshot and explain e a bit it would be very helpful
Joker6996: anyone know good YouTube channels for extremely newbie python
Tanvir: @Joker6996 I would suggest Socratica
Joker6996: I'll look over it right now, thank you
Manchi_o6o7: How can I open up an old chat with someone
derjack: struct is this the great escape? https://boardgamegeek.com/boardgame/624/quoridor
derjack: Manchi_o6o7 you cant unless he follows you or says something here
derjack: Tanvir // angle between your pod orientation and the direction of the next checkpoint
derjack: if i understand correctly, 0 means checkpoint is straight ahead, 30° is slightly left and -30° is slightly right
Manchi_o6o7: Why is the Travelling Salesman problem NP Hard, when we have the Hungarian algorithm which solves it, and it works in 0(n^4) ?
derjack: does this algorithm work for any type of graph in TSP?
Uljahn: does it really solve TSP?
Manchi_o6o7: I can't find any article on the net where it says that it doesn't finds the optimum path
derjack: i think the burden of proof is on to prove it finds the optimum path
b0ot: roughly speaking how many loops before a program timesout
darkhorse64: derjack; quoridor is almost the great escape with two major differences: two player only, a player jumps above the other player when in contact
derjack: player jumps? oO
derjack: oh, he does
DomiKo: Hi
b0ot: Has anyone done the 'Robot Show'... I'm struggling to see how I wouldn't need to check 2**N starting positions
GroutchKeu: o/
derjack: youre gonna need... math
b0ot: well I solved it off of test cases, but I don't really understand why that is the case
AryanTripathi: hello

Joker6996: C:\Users\Jhorm> python_examples
'python_examples' is not recognized as an internal or external command,
operable program or batch file.
Joker6996: what does this mean
PawkoKoks: uwu
derjack: oh my
emh: damn. without avx I get 3M iterations, with avx on gcc9 and gcc11 I get 2M iterations and on gcc12 with avx I get 4M iterations. seems like the older versions are bugged
emh: hope CG will upgrade to gcc 12 then
emh: ahh well.. I found a workaround, enabling avx2 only for specific functions and got 3.8M
struct: derjack I finally managed to get sub 100 https://www.codingame.com/replay/640989171
j4at: nice struct what did you use ?
struct: still beam search, I just made the sim a bit faster
struct: ok I improved it a bit more since that replay
struct: sub 99
struct: https://www.codingame.com/replay/641054548
struct: it finally can go full speed to last checkpoint now
derjack: :tada:
ethaneCH3CH3: hi, why do I get this error?
ethaneCH3CH3: Couldn't find the question related to this contribution
j4at: Well, im training my NN rn almost done :) The first time i didn't copy an invisible character!! So had to retrain again because I didn't save the parameters!! I don't know about beating beam search but I Hopefully I beat Wontonimo atleast!
Gr0mph: Hi, In C, what is the best method in codingame to get time ?
TNL: ZXHDB
struct: top NN is rank 3 j4at
TNL: yasuo gank team 20gg
Gr0mph: I have find two that seems work: gettimeofday with sys/time.h and clock_gettime... is it enough good ?
j4at: ow damn
j4at: Did they use GA or RL ? or other ?
struct: no idea j4at
struct: Gr0mph I dont use C, in C++ I use high_resolution_clock but I dont think C has it
struct: I guess you could try one of these
struct: https://www.geeksforgeeks.org/measure-execution-time-with-high-precision-in-c-c/
struct: Just make sure to start the timer after you read the first input
Gr0mph: Hi, Thanks
Gr0mph: I have check the article and I found the two method that I have already find. So that's the solution. :)
j4at: I'm reimplementing the "GAN RL" idea now but with 4 actors and 4 critics. struct https://ibb.co/LQP5qR1 mine rn doesn't have NN's with "-" So no "GAN RL"
struct: I will have to look up what GAN RL is
derjack: for mad pod racing?
j4at: Search Race
j4at: Well you need to look up GAN and RL separately. Because I made up GAN RL
darkhorse64: struct: what kind of eval are you using for SR ?
struct: nc_id * 50'000 - pos.distance(checkpoints[nc_id] - vel);
struct: On that replay I used 7 actions but my bot on arena doesnt do that well with it
struct: the submit one has 5 actions
darkhorse64: I use nc_id - distance to checkpoint(nc_id)/distance between checkpoints(nc_id, nc_id -1). The vel is an interesting idea
struct: it was suggested by jacek
elie.f.asmar: hello,
darkhorse64: I'll try it. Thanks
elie.f.asmar: is this chatroom exclusive for the Search Race minigame, or is it common across all challenges
struct: its common
mistcutter713: ji
mistcutter713: masd'
elie.f.asmar: When a challenge is tagged to be solved through a genetic algorithm, and the response time per turn is <= 50 ms, how am I supposed to control the algorithm convergence time? Should I keep trying or just try to solve the Search Race puzzle using bare trigonometry
struct: you can use whatever algorithm you see fit
struct: on search race there is a bug for some reason, I'm only able to use 30ms per turn
struct: You need to start the timer after reading the first input
struct: Then you must check it to see if you still have time, I check the timer every N iterations because its expensive.
j4at: I think you are asking about how to train the NN in 50 secs? elie.f.asmar.
Use a simulation and train the NN locally and then copy the parameters to cg
j4at: ms*
elie.f.asmar: not a neural network
elie.f.asmar: a genetic algorithm that needs time to mutate an optimal solution
elie.f.asmar: The basic genetic algorithm implementation
j4at: ow
j4at: I don't think that's a good idea
elie.f.asmar: I learned that, the hard way :p
struct: I think some people do use GA here
DomiKo: ofc
struct: I think jacek uses it
darkhorse64: It works. You run it for 50 ms, pick the best move and reuse your populations
DomiKo: yes jacek uses it,I uses it too
elie.f.asmar: Regarding simulations, does that mean I have to code the exact game engine, train my neural network and then generate the model
struct: with my beam search I get around 30ms 800'000 avg sims per turn
j4at: Jacek uses GA in Search race ?
elie.f.asmar: @struct, do you use c++ with multithreading and optimization?
elie.f.asmar: (pragma)
struct: There is no multithreading here
struct: I do use pragmas, but thats about it
j4at: yep 1 core
elie.f.asmar: Well I am using JavaScript which is theoretically much slower than c++ in terms of execution time
DomiKo: "theoretically" lol
DomiKo: it won't be a problem to make it work
DomiKo: you need very little time to have a decent result
elie.f.asmar: consequently I think that I need to optimize my algorithm
struct: Maybe I'll try to use GA, I never used it before
darkhorse64: I have got the best results with BS but GA is close
struct: Whats your beam width?
struct: I use around 10k
darkhorse64: depth 30, width 8K
AryanTripathi: sup guys
j4at: using utf-16 I always get 1 character missing :(
derjack: yes, jacek uses GA
derjack: you can never be sure of 'optimal' move, so you use all the time available
AryanTripathi: why even use utf 16
derjack: GA, SA, BS... given the same eval they should be equivalent given different hyperparameters
j4at: To compress my NN
darkhorse64: I tried BS because aftezr quantization, I had very few actions left (-> low branching factor)
derjack: how big is your NN you need to compress it?
j4at: 80k weights
j4at: parameters*
derjack: oh my
j4at: Go big or go home :p
derjack: -That.- She.
DomiKo: 80K is ok. Around 40K chars
j4at: float16 so 80k chars using only utf-16
j4at: http://chat.codingame.com/pastebin/856cb186-ab28-4e83-a186-b4a962e2e2d0
j4at: Anything wrong with my code ?
j4at: Okay I found the problem :)
DomiKo: was is there?
DomiKo: was it there*?
j4at: Yeah
j4at: Not sure how this works but this fixes the issue
j4at: parameters = np.round((parameters - min_)/(max_ - min_) * 50000+5295).astype(dtype=np.uint16)
j4at: my guess is you can't have 0 as first byte
j4at: or 2 zeros "0"
j4at: I will try
therealbeef: certain byte combinations are illegal in utf-16, iirc
thethiny: Thanks @AbrahamJLR I saw your response now
derjack: so youre gonna submit?
j4at: I will need to train again! :3 Didn't save parameters again
derjack: quite forgetful
j4at: Well, i though i will not need to save parameters uncompressed bc I was so confident :'D
j4at: perfect solution is this
j4at: parameters = np.round((parameters - min_)/(max_ - min_) * 55038+256).astype(dtype=np.uint16)
j4at: for maximum accruacy
j4at: 55039*
derjack: why 55039
derjack: is this because above the utf16 char count as 2?
j4at: I don't know :'D If I use +55039 i get an error :3
j4at: I don't know how utf-16 really works only utf-8. too lazy to check
derjack: some are illegal and can be intepreted as \n for example
j4at: well solution for "\n" is to use three double quotes strings in Python. I think there is only 2 illegal characters.
j4at: ignore what I said above
j4at: 55296 is out of range not "illegal". all illegal characters are smaller than 256. other than 2 cases which doesn't include \n

andyyyyy: How hard is getting used to javascript from python?
Ayza: well it isn't that hard but it depends on you and the time you've used python for
Ayza: the hard part for me was getting used with the curly braces and to put brackets in if statements
Ayza: but didnt take long to get used to
Ayza: (conditional operators aswell)
andyyyyy: what I can't get used to is how much smaller the standard library is
andyyyyy: and how many things are much different
andyyyyy: like for example .sort() sorts a list of strings based on the first indice value...
Ayza: that too, I was used to rely on python's standard library
Ayza: str.isdigit(), str.isalnum(), etc
Ayza: while in js you have to use regex
andyyyyy: or relying on collections or itertools libraries :)
andyyyyy: defaultdict or Counter is my favourite
andyyyyy: Do you have any suggestions on how I can learn JS better then
andyyyyy: im thinking i shouldn't think of JS as "python with extra syntax" but just learn it from the ground up.
DonLarry: maybe just practice
andyyyyy: Yes I just wondered how best to learn and practice :)
Ayza: what I would do is remake projects I did in python in js
Ayza: and focus on coding in js more to get used to the syntax
Ayza: ^^that alone teached me a lot by googling
andyyyyy: true just kinda unsure of what is best practice in python not so much in JS
andyyyyy: like i can probably hack it together to work, but will it be good is the question
OEtzi007: Anyone here interested in giving a final approval to my Clash of code contribution :) Would be greatly appreciated: https://www.codingame.com/contribute/view/21498ca08c680a57e17ea629cc1ec012bafd8

OEtzi007: thanks :)
thethiny: yo
thethiny: can anyone give me an example of a test case validator?
thethiny: I don't understand what that is
thethiny: okay I thin I got it
thethiny: if the question is to convert abc to ABC
thethiny: then test case1 would be abc, ABC but validator would be aaa,AAA
thethiny: right?
Ayza: A validator gotta test the same case for it's testcase but stay different
Ayza: for an example if you need to get the nth prime number: if the testcase is a small number try to make the validator a number that is in the same range or slightly bigger
thethiny: alright, thanks
bobth: i threw three games of clash of code and dropped 40 ranks

struct: Also top might be hardcoded
struct: I know rank 3 isnt but dont know about 2nd and 1st
j4at: Yes, But i prefer. To show you the new version.

Westicles: hardcoded?
struct: I think it is westicles
struct: not sure though
struct: the validators are public
Westicles: oh, sorry I was mixing it up with BR2048
HenroLST: uh to contributions auto save? Or if I take a break to stop working on it it'll disappear
struct: you can save it I think?
struct: if you click send it will save
struct: you can make the status private if you dont anyone else to see it
HenroLST: Okie, thanks!
HenroLST: I haven't gotten around to working on the solution because Im too tired :sweat_smile:
HenroLST: Oh it seems i cant send unless my solution actually works
