A lot of people here said they are dissapointed with bitboard for chess program. Yes, chess has 64 squares but checkers has 32 squares. At first, I think it must be perfectly matched with checkers . The result... My old program , single array of char [55], seems like board[12x10] in chess, is faster approximately 100% of any position. Of course,only gen(),makemove(),unmakemove(). >Comparing functions is ok, but it'd be much more interesting to >compare to whole engine (including make/unmake and the eval). >There are neat things you can do with bitboards in the eval with >simple boolean operations. I agree. Now,I try to make use of its advantage in eval(). But, checkers has much less complicated eval() than chess. I'm not sure the advantage can compensate its drawback. Thank for your comment.
