Lime starts to get stronger...

Postby Richard Allbert » 23 Jul 2005, 14:43


Having released what seems to be the weakest active engine available, I have made some big changes..

-Added 32MB hash (20 bytes per element, replace always, store at depth 2 and above)

-Added futility pruning, killer moves

-Changed move ordering scheme

-Added pawn structure evaluation, support points for pieces, separate endgame and middlegame evaluation functions.

I tested the engine in a 25'+10" Gauntlet vs some of the other weak engines, and results were good, especially the improvements in endgame play.

Hopefully, I can release it in the next few days. More testing first! :D
