[Caml-list] bitboard - howto

[V Krishnakumar]

Hi! all,

Iam new to OCaml. Iam trying to write a chess engine.
In order to represent the board, I need bitvectors. How do I get bitvectors ? (i need exactly 64 bit vectors).

also pointers to similar board games would be really appreciated.

thanks in advance,

-Krishnakumar

You can use the Int64 module of the Stdlib wich has bit-based operations.

Try Int64 (http://caml.inria.fr/ocaml/htmlman/libref/Int64.html)

I wrote a bit vectors library, available here:

But, as already suggested by others, using the Int64 module from ocaml
standard library is clearly a better idea in this particular case.
