@emanresuA C bot #1

Sad, reran it to fix a coloring issue and now it's near the bottom again

Bubbler

so it really is luck-based lol

mousetail

@Bubbler Median scores seem mostly pretty consistency, but occasionally one bot gets really lucky or unlucky one trial

There are a few bots that have 1 specific weakness that makes their scores more inconsistent while others are less specialized and have no huge advantage against specific opponents

was trying to come up with a knight solution to ur challenge (cuz its like the lotm and all) but i realized that idek how to download a local copy of knight lolol

mousetail

@AidenChow The entire point of knight is that there are plenty of implementations to choose from right?

Aiden Chow

@mousetail yes, the problem is pretty much none of them are up-to-date

mousetail

That sucks

I had to search a long time for a whitespace interpreter that was bugged in a way that made the challenge solvable

ais523

@mousetail: it looks like you missed the change from LC_ALL to LANG for the Jelly submissions

mousetail

@ais523 No it's fixed

Aiden Chow

06:59

hmm theres some knight interpreters on tio that work, maybe u can use one of those?

mousetail

@AidenChow github.com/knight-lang/c/tree/master/ast what's wrong with this official one? Claims to be updated to 1.2

ais523

ah, in that case codeberg.org/Mousetail/Radiation-Hardened-Koth/src/branch/main/… is probably out of date

mousetail

@ais523 Yea I just updated it a few minutes ago

Aiden Chow

@mousetail idk, steffan said in the knight chat that he couldnt get it to work, i havent tried it myself tho cuz i dont have c

ais523

ah, I refresh and it's there now

comments crossing

The Burrowing Wheel is still unexpectedly dying to attacks on the chaff, maybe there's a second bug in it

mousetail

07:02

@AidenChow C is such a pain to get to work in windows, WSL is a lifesaver

Aiden Chow

@mousetail hmm could u get it to work? not big brain enough to figure it out

mousetail

@AidenChow Do you have WSL?

Aiden Chow

idk what that is

Bubbler

WSL

mousetail

Other option is minGW but WSL is easier

Bubbler

07:07

ye

Aiden Chow

ok so i just run the command in the cmd? do i need admin access??

mousetail

Probably yes

Aiden Chow

also i need to download c language right

@mousetail oh i dont have admin access :(

mousetail

F

Aiden Chow

ok well there are some interpreter on tio, could that work?

mousetail

07:12

@AidenChow I won't be able to run it but you can prototype things there of course until you can test a offline interpreter

Can you link the knight chat room please?

Aiden Chow

:( i already have working code, wouldve submitted an answer by now

Knight

mousetail

@AidenChow You might as well submit it, I'll see if I can run it. There are already 3 submissions so far I can't run so you wouldn't be the first

Aiden Chow

@mousetail oh rly? ok

ok actually i think another problem i just realized is that knight doesnt require implementations to support print stuff outside its ascii range, but some implementation still do

specifically, the interpreter on knight-lang.netlify.app supports printing all chars

so like idk how to download that one

mousetail

@AidenChow Seems to be a pure JS one, I see no outgoing requests

Who built it?

Must be someone from here considering it has the "format CGSE post" option

Aiden Chow

@mousetail steffan made the website

mousetail

07:21

Is the source code of the website available?

Bubbler

you could just grab js code from devtools maybe

Aiden Chow

@mousetail ¯\_(ツ)_/¯

ik the (probably) same interpreter is on dso as well

mousetail

Ok the unmimified interpreter is just pasted into the HTML it seems

What is it with code golfers and not mimifying your JS?

Aiden Chow

i think i find the interpreter: gist.githubusercontent.com/Steffan153/…

mousetail

@AidenChow You could probably port this to node.js with a little effort then use it for your submission

Aiden Chow

07:25

idk js lolol

mousetail

That's going to make the process significantly more difficult

Adám

@mousetail mimifying?

mousetail

Yes

Aiden Chow

@mousetail :((((

Bubbler

07:48

@AidenChow Wrapping this in the following code should work:

const fs = require('node:fs');
const input = fs.readFileSync(0, 'utf8').split('\n');
const source = fs.readFileSync('source.knight', 'utf8');
const Knight = (() => {
  ...
})();
Knight.run(source, input);

@mousetail ^

assumes source.knight in the current directory

Aiden Chow

@Bubbler dang how u find this out

Bubbler

I just happen to know how to read files, and that number 0 is stdin

not sure with the utf8 part though

mousetail

@Bubbler Splitting on \n would make it impossible to read bots spanning multiple lines right?

Bubbler

No, it takes entire input and then it splits by newline, giving a list of strings

mousetail

ok ok

Still reading as utf-8 will fail a lot, I see a lot of other bots using ISO-8859 encoding but I'm not actually sure why. Might help a bit to use that encoding instead

Bubbler

07:59

let me try out some stuff

ok, change the input line to const input = String.fromCharCode(...fs.readFileSync(0)).split('\n');

this converts each byte to a char of that charcode

mousetail

You would need the reverse process at the end

Aiden Chow

the code has to be =<256 bytes right?

mousetail

Yes

Aiden Chow

k gotta golf it down a little

Bubbler

const output = Knight.run(source, input);
fs.writeFileSync(1, output, 'latin1');

seems to work for nonascii output

mousetail

08:12

nice

Aiden Chow

ok posted it

mousetail

@Bubbler Can you post the full version as a gist?

Aiden Chow

im interested to know how badly my bot will do lol

mousetail

Well MVP exists so you are probably not last

Bubbler

no gist cuz it's blocked at work, see knight room for full code

Aiden Chow

08:21

@mousetail lol truee

second last is a possibility tho

mousetail

09:48

@AidenChow You are second to first for the moment

emanresu A

10:39

@mousetail There's got to be a bug with your controller. Most bots are invulnerable to example C bot (at least for the first few rounds) and can break it in one go

How many times are you running it?

mousetail

@emanresuA 50

emanresu A

Are you randomising the order?

mousetail

Yes

emanresu A

And how long does 50 take? Would 500 be feasible?

mousetail

Example C bot removes the first character if it can't find another one

@emanresuA Takes about 5 minutes currently

emanresu A

10:41

Ah ok

mousetail

All of my bots default to the first character if it can't find another matching the pattern

emanresu A

Oh wait nvm, what does ECB do?

mousetail

ECB?

emanresu A

Example C bot

mousetail

It removed the first character so that (x&186)^'(' is true. If it can't find any it removes the first character

This matches parenthesis but also a few others

I mean when that is false

emanresu A

10:46

Ah ok

mousetail

The characters exactly are ['(', ')', ',', '-', 'h', 'i', 'l', 'm']

The comma might also be giving it a lot of kills

pxeger

@emanresuA controls the interest and exchange rates of the Euro

Governs the rules and organisation of cricket in England and Wales

mousetail

Someone should host a cricket KOTH with a ECB participating

Aiden Chow

16:16

@mousetail how da hell is that even possible, wow

like my bot is literally just choosing random chars, no strat at all

wow a lot of bots are targeting my comment at the front of the code, didnt expect that to work so well

mousetail

16:54

Most bots have various ways to make others avoid their "critical" parts. Shooting randomly avoids those defenses.

At least that's my theory

thejonymyster

maybe it should have been deterministic

theres enough "randomness" in terms of player order / deterioration state

mousetail

@thejonymyster My last attempt at a KOTH I wanted everything to be deterministic and got a lot of negative feedback about that rule

thejonymyster

oh lol fair enough

that's surprising to me, i don't see why people would care about that lol

mousetail

Most KOTHs I've seen on this site are very vulnerable to random starting conditions.

I think using the median helps a lot though, most bots have a approximately consistent median

Aiden Chow

@mousetail yeah that could be it, i noticed that my bot only survive 600 or so total rounds while the other top bots were surviving like 2k total rounds

mousetail

17:30

@Steffan Your bot is still giving invalid output

The output was "211 l" but the closest l is at position 213

Steffan

17:56

@thejonymyster No I'm bruhing at my solution for not working

This seems to be another bug in Vyxal :/

Actually nevermind, it seems to be working fine

@mousetail try adding the Ṡ flag please

so just vyxal vṠ

mousetail

Ok

thejonymyster

@Steffan smh @lyxal why did you make such a stupid buggy useless lang that nobody ever uses and isnt even golfy and...

mousetail

My laptop is having a lot of trouble running the controller now, I can barely do anything else while it's running

@Steffan That seemed to fix it

thejonymyster

@DLosc some sort of ungodly fusion may be in order

ragged multidimensional arrays :P

mousetail

18:12

F nope, the bot worked when I did a quick test but now I ran it for a while and it survived never again

Bruh

Bugs, bugs, bugs... That's vyxal

emanresu A

@mousetail Try running with the same thing as ais' answer?

mousetail

@emanresuA You mean with lang=x ?

emanresu A

ye

mousetail

I think it's still set though, environment variables are shared unless I explicitly set them to something else

Steffan

21:07

@mousetail which solution does it crash on?

Steffan

21:36

@mousetail See above. I ran the controller locally and it worked fine.

Gist with the results: gist.github.com/Steffan153/4ddc0f965f8b7bd9a4d49052cb401093

@Steffan my bot drop down quite a few places :|, ig i got really lucky getting second

is it allowed revise ur bot, like make a version 2 @mousetail
