My checkers program has developed some annoying quirks (read: bugs) and I haven’t made any good progress in figuring them out, except to assertain that most of them appear to be centered around the use of transposition tables (when I disable the transposition tables, my program is much better behaved). Because I didn’t know what was wrong, the code has been mangled in a way I don’t like. Oh well. Rather than mangle it further, I thought I’d dig up some more reading material. The links o’ gold today are T. A. Marlsand’s older papers, including a review on game-tree pruning that seems to answer many questions. Good stuff.
Oh well. I’ll work on it this weekend.
