Q: Alpha beta beta pruning

mınxomaτ

@Upgoat I was debugging an assembler ported from visual basic (where array(0) has 1 element...). So. many. off-by-one-errors.

And of course the original code was horrible. The actual lower bound wasn't consistent. At times the first (i.e. the nullth) element would contain data, sometimes not. The only way out was to manually diff the hexdumps on paper.

Upgoat

8:09 PM

@mınxomaτ >_> sounds painful

mınxomaτ

It was efficient. I've written assemblers, but comprehending that code would have taken me months. So I just debugged the object files produced by the assembler :)

Some sites are integrated to chat . What additional sites should the chat support? One suggestion per answer.

If xkcd is in there then OEIS should also be possible, should't it?

@Upgoat That is probably just an informal survey, and way too old.

@CᴏɴᴏʀO'Bʀɪᴇɴ yeah

why is there var

9:26 PM

@AlexA. no, redefinition will be without the var. e.g. var a := 4, them to change it a := 2

@CᴏɴᴏʀO'Bʀɪᴇɴ you need var to define a variable

Cᴏɴᴏʀ O'Bʀɪᴇɴ

why not just let

idk, I can change it later if I want

I just added a skipper to my peg parser

so you can write ~ A B1 B2 ... and then any occurrence of A gets skipped inside all Bs

for example program = ~ whitespace stmt* and now you don't have to handle whitespace in your rules

and deeper nested skippers take precedence, so you can write number = ~ () [0-9]* to disable the skipper for parsing one number

mınxomaτ

@Geobits It easier to just leave "AI" out of the challenge. "Implement A/BP". That's algorithmic. You hardly have to know anything about "AI" (the topic) for this.

Geobits

True. The challenge could probably be pruned into a more understandable state by cutting some of the other stuff, too. I'm not the one you want editing it, though ;)

Upgoat

@Geobits Yeah, we wouldn't want it to turn into a "Make an evil AI that eats goats" challenge :P
