eulerscheZahl: miszu :rage:
miszu: HIII :D
miszu: how you doing?
eulerscheZahl: well played
miszu: wait
miszu: it will go higher
miszu: I improved even more but some cases timeout
miszu: eulerscheZahl check now :D
eulerscheZahl: 7th
miszu: yup, that's my max now haha
ANONYMOUS42: thank you Westicles
ANONYMOUS42: i finally found the problem with my simulation
ANONYMOUS42: what's the theory behind having x += velx + 0.5 * accx
ANONYMOUS42: i thought it would be just x+= velx and velx+= accx
ANONYMOUS42: i don't understand that + 0.5 * acc part
miszu: eulerscheZahl no but thanks a lot. You gave me good idea where to improve and it helped me
eulerscheZahl: no problem, i'm always happy when others play "my" games
eulerscheZahl: afk now, breakfast then work
miszu: okay have a good day :D
derjack: tutorial games like onitama?

bdrnglm: I've tried that link a long time ago. Since then I can't take another test anymore.
bdrnglm: Is there a way to take that test again ?
FollowerOJ: oh
HARRYPOTTERFANATIC: Hello, peoples.
None121232: You and your buddies are bored and decide to throw watermelons off high places onto the ground (Dont try this at home).
The watermelons are thrown perfectly horizontally at a velocity of V from a height of Y.
You decided to calculate the time it took in seconds (t) - rounded to the nearest integer, and the horizontal distance (X) it travelled before hitting the ground in meters.
None121232: can anyone solve it?
xoxoixo: guys does tthis thing really help
Uljahn: what are you talking about?
ForgottenSpoonAndHisDog_b2e2: hello my new friends
kimsejin123: hi
GreatStopwatch_f89: Hello :)
DX09: hello
ForgottenSpoonAndHisDog_b2e2: :grinning:
kimsejin123: ang gimozzi
eulerscheZahl: None121232 this doesn't look solvable as it is. What are the known values? the height?
Uljahn: None121232: find the time of the free fall, multiply by horizontal velocity, ez
GreatStopwatch_f89: gimozzi wdym?
miszu: qq for all. The CG sponsored contest, is it hard to reverse engineer it?
eulerscheZahl: not that hard. you will know when you did it
DJBlueChild_ffef: .
HARRYPOTTERFANATIC: Hello, peoples. What have I been missing?
Uljahn: a ban?
LagunaElectric: ?
HARRYPOTTERFANATIC: ???
LagunaElectric: Why a ban?
eulerscheZahl: repeated spamming for days
Uljahn: for your contribution to coding-related discussions being nonexistent
TheBlueBias: HARRYPOTTERFANATIC ask a ban... :rofl:
xoxoixo: anyof u guys got tips or tricks for me
Astrobytes: Never eat the yellow snow.
xoxoixo: i just started programming in school
xoxoixo: still here?!
TheBlueBias: ZappastroBytes
Astrobytes: ;)
Uljahn: xoxoixo: learn the basics, practice, learn advanced stuff, practice more etc.
MASTER123: : )
miszu: ok so the reverse engineering optimization problem... no idea how scoring system works. Feels like for COD BO: The number Mason... what do they mean?
MASTER123: :joy:
MASTER123: :no_mouth:
MASTER123: :heart_eyes::yum:
eulerscheZahl: won't tell, figuring that out is most of the fun miszu
MASTER123: viet nam
eulerscheZahl: MASTER123 please stop
Astrobytes: Stop spamming emojis right now.
Astrobytes: Or else
MASTER123: ok
eulerscheZahl: kick or ban
because it's still a few days for trick or treat
MASTER123: ...
Astrobytes: lol
MASTER123: stop
Astrobytes: hammertime?
miszu: there are 6 inputs to figure out. One of them is just the number of loops so that is nice... it's just the 5 others.. the outputs... and the scoring system
MASTER123: https://www.codingame.com/clashofcode/clash/19979951ca4872a314516de75994fe3de3a2139

TheBlueBias: eulerscheZahl: does the cgfp referee interpreter fully handles unicode chars in the program?
eulerscheZahl: it does as far as java does
eulerscheZahl: my solution prints the unicode from int values, easier than copy-paste
TheBlueBias: Right. I copy-pasted though... ^^' But two validators don't pass with this new code, and I don't get why. :thinking:
eulerscheZahl: have you tried opening the contribution is you see what's happening?
TheBlueBias: Running the referee you mean?
eulerscheZahl: https://www.codingame.com/demo/8243058ea8a7c2a0894e9b9196533a9a8a52bb
eulerscheZahl: so you see the validators
TheBlueBias: Oh! Well I checked them on github, but I'll check again this way. Thanks!
TheBlueBias: Can't open validated contribs yet.
TheBlueBias: The validators aren't all presents in this link. Or perhaps I can't see them because of my level?
miszu: eulerscheZahl how long did you need to figure out the pattern?
TheBlueBias: Pattern?
SUNNFIT: Hello guys
eulerscheZahl: i don't really remember, did that years ago. 1 afternoon maybe
Robot15: yo
Wontonimo: hey miszu, you beat me in 2048
Wontonimo: tell me your secrets!
Wontonimo: have you moved to TheBlueBias for good, or are you still using your other account?
TheBlueBias: What other account?
Wontonimo: oh
Wontonimo: ;)
miszu: Hey Wontonimo :D
Wontonimo: :wave:
Uljahn: Wontonimo: it's not a secret java has no chances vs C++ with pragmas
miszu: I was waiting for you to tell you about it
Uljahn: gratz miszu
miszu: thanks Uljahn
Wontonimo: ah, so first is to switch my solution to c++
miszu: yeah you need some speed here
miszu: it doesn't matter that much but it's helpful
miszu: however figuring out the CG reverse engineer problem on the other hand... I am staring at those inputs and outputs and can't see a pattern
Wontonimo: hehe
Wontonimo: i won't spoil it for you
miszu: lol no one wants to spoil it for me :P
miszu: that's okay
eulerscheZahl: because that's the most fun part of the game
miszu: but it took you a lot of time to figure it out?
Wontonimo: i can give you a hint
Wontonimo: but it'll spoil it
miszu: ok don't say it
TimothyAlexisVass: miszu did you look at the hints?
Wontonimo: it took me a while, yes. lots of looking at patterns, playing with inputs
Wontonimo: no no ... don't look at hints !
miszu: haha okay
miszu: I won't look at it
_NikJ: Finally beat the MightyCarlo in UTTT, jeez what a task
miszu: all I know is one of the init input is just for the loop :P #cryptography
Wontonimo: once i figured out the secret, the game lost all interest. really, figuring out the secret was the really rewarding part
miszu: not even trying to beat the score?
Q12: I don't agree Wontonimo
Wontonimo: congrats _NikJ !
Q12: when you reveal the secret the game becomes a regular CG puzzle
miszu: Q12 is right.
Wontonimo: it does. yes. *just a regular cg puzzle*
miszu: even the stupid scoring I can't understand lol
_NikJ: Switched to a TS variant, was 1st for a while but couldn't beat the MightyCarlo @Wontonimo
_NikJ: How do you tag people? I forgot xd
Wontonimo: TS variant?
_NikJ: mcts
Wontonimo: yeah, you tagged me. you don't need the "@"
_NikJ: If you recall I did MC sims
Wontonimo: just the persons name
_NikJ: Oh that's neat
darkhorse64: I still have not figured out everything yet. Not sure for the scoring and maybe for the entities
TimothyAlexisVass: http://chat.codingame.com/pastebin/27591350-cf61-46b9-8d30-2fb171d05d97
darkhorse64: But that was enough to climb high
Q12: I won't say it lost all of it interest, because the puzzle for itself (without the secret of discovering the puzzle) is quit good
Wontonimo: yeah, maybe i'll go back and give it more love
darkhorse64: I am interested in 2048 hints, though
eulerscheZahl: add up the hex digits TimothyAlexisVass?
miszu: darkhorse64 :D
eulerscheZahl: just do the snake and beam search
Wontonimo: hey _NikJ , 2 things: 1 - you can press tab after typing the first part of someones name and it will autocomplete if they are online
Wontonimo: 2 - do you know about the "solver" for MCTS?
miszu: yeah snake a beam search is what you need
miszu: and*
_NikJ: Wontonimo, thanks, and no, I don't
miszu: also make sure you remove dups states otherwised your beam will get suffered
DomiKo: how about problem with 2^16?
darkhorse64: That's what I do but it does not go high enough like all ppl around 25M
Wontonimo: i'll dm you about "solver" if you like
miszu: darkhorse64 also check hardwarre limitations like int32 vs int64
miszu: that was one of the issue as my ai decided to play dumb moves lol
miszu: because I overflowed.. oupsie haha
TimothyAlexisVass: oh
eulerscheZahl: do you print all your actions? the full beam depth
darkhorse64: I use 64 bits otherwise it blows up. I print only part of the beam and restart from this position
eulerscheZahl: sounds reasonable. and you also remove duplicate states from the beam
TimothyAlexisVass: Is there anyone who is proud of his/her CG reverse solution?
I figured out what it was, but I haven't yet thought of a way to move.
darkhorse64: Not this one
eulerscheZahl: there are lots of duplicates. your beam will quickly become a single state many times
darkhorse64: I have no hashing
TimothyAlexisVass: I mean to survive longest...
darkhorse64: Aha, probably the culprit
eulerscheZahl: and soon i'll drop another rank
eulerscheZahl: sigh
_NikJ: My goodness, I just visited CSB leaderboard after not checking it for 4 years. I love how everyone is fighting within 35-38 points mark and then there's the top 3 guys. With reCurse reaching an insane 60+ points, just wow
Uljahn: just NN things
eulerscheZahl: https://www.codingame.com/contests/spring-challenge-2021/leaderboard/global
he completely destroyed us in the last contest
darkhorse64: I have played with many parameters but whatever I do, after 32K is reached, my search goes into a dead end. The single state may explain this
_NikJ: I love how FAR away he is from EVERYONE
eulerscheZahl: without him i would have said we are close to perfect gameplay, thus the similar scores
eulerscheZahl: but in reality we are just equally far away
darkhorse64: It reminds me of something written by Martin Fierz (Checkers fame) who thought checkers engines were perfect just before they got wrecked by NNs
miszu: darkhorse64 I had that issue where it became single stated
miszu: I created a set and checked how many states were unique
miszu: found out only I had like 4 or so
miszu: hashing is simple here as it is only a 4x4 grid to hash
_NikJ: I recall him wrecking everyone on fantastic bits, few years back, by A LOT eulerscheZahl
miszu: eveyrthing else is derived from the 4x4
miszu: did recurse used NN in previous competition?
Wontonimo: yes he did
miszu: bruuuh
miszu: how many repetitions of sims he did before the training was complete?
eulerscheZahl: https://www.codingame.com/forum/t/spring-challenge-2021-feedbacks-strategies/190849/67
_NikJ: Apparently, a lot more (or just better) than everyone else, considering how much he wrecks all others miszu
darkhorse64: Time to dust my Zobrist hashing.
eulerscheZahl: as far as I know this is the most liked comment on the entire CG forum
**eulerscheZahl uses Zobrist for 2048 too
Gabbek: hello everyone :)
eulerscheZahl: hi
_NikJ: HA! I knew I wasn't crazy, I remember a blue avatar absolutely destroying CSB with NNs back then (blue avatar being pb4)
darkhorse64: No boss for LOA this evening
Gabbek: how's the day going? What are you up to guys?
eulerscheZahl: not much
eulerscheZahl: kotlin heroes in 2 days
eulerscheZahl: then the Huawei contest
YassineGuem: learning some javascript, for developpement studies
darkhorse64: Next CG contest in more than six months, if any
Gabbek: cool, I wish you good luck! I was hoping I would enjoy the next contest but... uhh, gotta wait for non-escape contest I guess :|
eulerscheZahl: so you have to look for alternatives
eulerscheZahl: will be the first CG contest since the Accountant that i'm missing
eulerscheZahl: even played detective picaptcha and locam sprint
Gabbek: there's something pretty cool on kaggle, I remember nerchio sharing the link (think it's on CG discord somewhere)
eulerscheZahl: Lux AI?
Gabbek: oh yes, that's the name
eulerscheZahl: what turns me off is the extremely long duration
miszu: the real question is how he got a hand of an rtx 3080
miszu: I am trying to buy one
darkhorse64: exchange bitcoins against RTX
miszu: I can afford one it's just the availability
darkhorse64: RTX are all used for mining
Gabbek: I haven't really touched any contests outside CG - just writing some bots to gold league and trying to get rid of truly crappy stuff. I'm happy as few days ago I re-wrote my fall challenge 2020 to something much better and managed to get top 100 gold - pretty happy with it, compared to previous silver bot :(
miszu: not with the LHR version or w/e the acronyme
Gabbek: btw -- pretty good exercise: https://www.codingame.com/training/hard/the-hidden-fortress ; lost few days on it, but I'm pretty sure that others have solved it in an hour or a few, heh :)
darkhorse64: yet another BFS ?
Gabbek: a logic puzzle
eulerscheZahl: i have a feeling that it might be a max flow problem, but not sure (didn't think about if much)
darkhorse64: a picross
eulerscheZahl: if that's the same as nonogram: no
Gabbek: a bit different than picross I think, but I haven't seen anything similar before
darkhorse64: yeah, picross is french. That's what I thought reading the statement. I should read twice then
eulerscheZahl: because the nonogram gives you numbers for the edges
Gabbek: recently I found something quite unique: apparently slay the spire (pc game, roguelike deck builder) has mod support and you can develop your own AI to play the game :)
Gabbek: https://www.youtube.com/watch?v=obtg0tredJg
Gabbek: pretty old topic, but I've never seen it before - if anyone would be interested I can help out with setup, as it's a bit confusing but it's working perfectly
JacobTheCoder: hi
Gabbek: good day
JacobTheCoder: im tryna get better with my .lua any tips?
Gabbek: sadly I don't know any lua; most likely there are some good tutorials on the web, but that's about it, sorry :(
miszu: ok I looked at the hint. To be honest, I would not have figure out because i thought it was something to do with math
Gabbek: have you found it on the web miszu? I tried to find something after like 3 days but... nope, no idea how it's called :D
miszu: oh no there is a hint section in game
miszu: give you starting point but that's all
Gabbek: are we talking about the hidden fortress puzzle, or did I miss the context by mistake?
miszu: it's the coding game sponsored contest
Gabbek: ah, okey, I see what you mean now, thanks for clarification!
struct: Are you going to change anything else in loa darkhorse64?
darkhorse64: No, unless someone asks for a change. I just need to find the time for writing the boss
**darkhorse64 should not try to fix his 2048 optim
miszu: come on darkhorse64 :D
darkhorse64: Actually, I already had a sort of hashing, using my eval
**darkhorse64 discovers his own code
miszu: *can darkhorse64 find his bug?*
darkhorse64: But I never checked whether it was OK
TheBlueBias: A rare picture of darkhorse: https://cdn-images-1.medium.com/max/1600/0*hpiMODx6OUkuU1f3.gif
TheBlueBias: Link fail... :(
darkhorse64: Do not click
darkhorse64: OK, time to leave
MSmits: it works fine if you copy paste it fully. Also it's exactly as I pictured darkhorse64
TheBlueBias: :smirk:
69razer69: how to start the coding escape i gathered my team and i want to start
eulerscheZahl: you wait 23 more days
eulerscheZahl: and 3 minutes
eulerscheZahl: gabbek can I see the fortress as a linear equation system?
or are there multiple solution so that only the 0/1 condition makes it unique?
eulerscheZahl: hm, worked for the first testcase. but not sure if it will always work out
eulerscheZahl: i guess i could just dump it in numpy and see what happens
Uljahn: :scream_cat:
TheBlueBias: same
jacek: :upside_down:
eulerscheZahl: ok, got the 100% correct. but still not convinced that my solution will always work
eulerscheZahl: 2 solutions are pretty much the same as what I did. and for the 2 others I have no idea how they work
eulerscheZahl: and somehow once again my solution doesn't show up for others
eulerscheZahl: hide and republish worked, shrugs
TheSilent_Boy: .
darkhorse64: #17. Near miss, eulerscheZahl
eulerscheZahl: :scream:
darkhorse64: My hashing was broken. Always question your code
jacek: hm?
darkhorse64: You got a 6M margin
eulerscheZahl: that's not much
eulerscheZahl: but as I told miszu already: i'm happy when others play my contributions. feel free to bypass me
eulerscheZahl: for this one i've learnt some internals of the SDK to encode the replay more efficiently
eulerscheZahl: otherwise the 1MB limit would have killed the idea
jacek: still this is not true 2048 :(
darkhorse64: Same feeling for me for my two contribs. I like when your contribs push the limits
darkhorse64: true 2048 scores less
eulerscheZahl: the known spawn is the big difference
eulerscheZahl: but also makes any known papers useless, which isn't bad IMO
jacek: i have yet to make the n-tuple for 2048 useful
miszu: "feel free to bypass me".
miszu: I will not invade your country
eulerscheZahl: invading my country would mean creating more complex contributions in CG terms
jacek: :scream:
darkhorse64: #15, :smiling_imp:
eulerscheZahl: and only 3M difference now
darkhorse64: I am not sure if parameter tweaking will be enough to win 6M
eulerscheZahl: 6M? already planning to beat Neumann?
darkhorse64: Just behind. I'll be happy to be within top 10
miszu: darkhorse64 YOU SHALL NOT PASS ME
eulerscheZahl: I once was. even first. long ago
eulerscheZahl: the creator's advantage
miszu: day 1: eulerscheZahl got first place while everyone still writing the sims :P
darkhorse64: For the record, my hair is not yet grey and I have no beard
eulerscheZahl: and trying to understand my github code
miszu: I was talking about me
darkhorse64: I was referring to TheBlueBias pic
eulerscheZahl: my beard is slowly growing, home office made me lazy
miszu: oh dammn... funny yesterday evening I was just 13th with like 50k difference or so from eulerscheZahl
eulerscheZahl: before I used to shave once a week
miszu: work from home for the win
miszu: companies wants to force hybrid stle
miszu: gtfo lol
TheBlueBias: Shave?
eulerscheZahl: now i shave once every 2 months or so
Astrobytes: A Bearded Toad!
darkhorse64: I am happy to see your avatar only
eulerscheZahl: a stubbly toad
jacek: TheBlueBias pic.. is this lavos?
eulerscheZahl: it's his old pic, just in blue, isn't it?
TheBlueBias: And upside down. But like the idea jacek ^^
derjack: upside down avatar? lame
jacek: did he kill the chat? oO
TheBlueBias: He?
miszu: jacek did you assumed his gender?
jacek: eeyup
TheBlueBias: Yeah perhaps she's a she, or a tree, or a triton. How dare you say 'he'? :rage:
TheBlueBias: #TheBlueWoke
Scarfield: #UhBeetleWok
Astrobytes: AnagramField
Scarfield: staroBytes
Astrobytes: hehehe
Scarfield: an anagram for "anagram" is "anagram"
miszu: get out
miszu: I rediscovered high school math. Trigs of a triangle. Crazy how rusty you can be not doing it for years.
Scarfield: must resist the puns
miszu: say it
MSmits: he wants to make puns about rust
MSmits: but he has been saving them up and is waiting for when more rust people are online
MSmits: timing is everything
Astrobytes: Rustacean baiting eh
Scarfield: switch Rustacean out with master

Astrobytes: TMIfield
struct: Damn I still have no idea how to improve move gen on loa
miszu: for the zombie game, the (n+2)th fibonacci you start at index 0 or 1?
miszu: nvm found the answer
BlueSnowflake_207c: 1
grape: For the Botters of the Galaxy game, which hero is your favourite? Mine is Valkyrie
MasterCyph3r: any c++ programmers want to help me out real quick with this puzzle? lol
Westicles: sure
miszu: darkhorse64 wow you improved!
miszu: I gave you motivations it seems ;)
PANDABOMB: Is this the discord for Coders strike back?
PANDABOMB: Can I somehow get the coordinates of the next nextcheckpoint?
Plizan: HI
PANDABOMB: hi
Cryptical: hello
BCassady: calling all clashers!
eeeeeee7es: hello clashers! :point_up::nerd:
BCassady: I JUST CODED
Wontonimo: OMG!
Wontonimo: what was it like BCassady?
Wontonimo: hey PANDABOMB, yes you can get all the checkpoint coordinates
Wontonimo: as you see them, save then in an array, then once you see the first one again, you know what is coming up next
Wontonimo: there are also only so many different maps, so you can hard code all the maps into your code and identify which map you are in by the first checkpoint coordinates
PANDABOMB: So you're saying that I should save coordinates as my pod touches them?
Wontonimo: yes sir
PANDABOMB: Is there a way to pull the coordinates of my opponent's current checkpoint?
Wontonimo: what league are you in?
PANDABOMB: Alright, so if I wanted to make a code that reacts to data pertaining to all the check points, I'd have to run that in the second lap
PANDABOMB: bronze
PANDABOMB: I just started
PANDABOMB: I'm trying to get my pod to start turning before it even touches a check point
PANDABOMB: So it drifts into the current target
Wontonimo: yeah, your opponents info should be available in bronze
Wontonimo: congrats for getting to bronze so fast
PANDABOMB: All I have their coordinates
PANDABOMB: That's it
PANDABOMB: I think
Wontonimo: if you simulate your pods location if it were to drift then you can check if drifting is the right thing to do
Wontonimo: the calculations are all listed in the writeup on the left if you scroll down
Wontonimo: down
PANDABOMB: oh okay thanks
Wontonimo: there is a 15% drag per turn, and a max turn of 18 degrees
Wontonimo: i used a loop to look 5 frames into the future and simply check if my pod will be in the checkpoint area in any of those frames. very simple check and it works really well. it doesn't take into account that I actually turn or change thrust
Wontonimo: if you do add those factors then it will be more accurate, but even just the friction and a look ahead of 5 frames will work wonders
Wontonimo: have you read about PID controllers PANDABOMB ?
PANDABOMB: oh interesting. I can tell that my grasp of C# is not advance enough to simulate what you're saying yet
PANDABOMB: lol
PANDABOMB: But I really appreciate the advice
PANDABOMB: I just finished a 3 month boot camp with the Tech Academy
PANDABOMB: Im' still pretty fresh and Im' learning
Wontonimo: would you like a hand with it?
PANDABOMB: idk if you are familiar with C# but this is where I'm at
PANDABOMB: https://pastebin.com/pU63gVQP
Wontonimo: I won't code it for you, but I can point out how it is actually easier than you may thing
TheManeatingCheesecake_ddf2: hello my friend
