It's the chips that search 200M nodes per second with an incredibly >complex evaluation function. incredible complex for a not-rated player. incredible simple for a player like me. They only claim to have an evaluation bigger than the PUBLISHED evaluations so far. Apart from gnuchess and crafty i don't know much about 'published' evaluations. The 40,000 general purpose instructions which makes up their complete evaluation function in deep blue sure ain't much to my standards. Saying your evaluation usual eating less than 40,000 GPI is a complete different statement as saying your evaluation function is totally comparing with 40k GPI. Apart from this discussion great discussion about FPGA. You're however comparing with deep blue. I'm only interested in how much faster my program can get if i for example put my evaluation to FPGA. What i'm doing in my evaluation is of course first adjust a bunch of variables and make lists with information to be processed later. Is this possible in FPGA, or does this require something that's hard to do in FPGA? Vincent >-Tom
