Hi Dann, >Phalanx has a really slow motor. Usually 100K NPS or so. Gullydeckel has a >barn-burner -- often well over one million NPS on my machine. If we could >couple Gullydeckel's move generator with Phalanx's eval, it might rule the >world. you allways tells us how incredible good Gullydeckel's move generator is... can you give us some numbers ? Here is my testing position, Vincent Diepeveen has put my nose on it to look how things are going: [D] rnbqkbnr/ppp2ppp/8/3pp3/3PP3/8/PPP2PPP/RNBQKBNR w KQkq d6 0 3 When I start with Quark, Quark produces in this position about 3.500.000 moves per sec. (measured this just with a huge for loop and allways call move gen and after that calculate created moves divided by seconds) At the moment Quark creates 8.300.000 moves per second here on PII/400 Vincent Diepeveen said to me that Diep creates on PIII/450 here 15.500.000 moves per second and crafty about 7.700.000 moves per second on PIII/450 Can you give us some numbers what Gullydeckels move generator does here... (Quark and Diep have 0x88 board representation, Crafty we all know... :) Greets, Thomas P.S.: Working on move gen is worth a lot, it is incredible, what the improvement brings in kNPS... And also it is really funny... At the beginning I thought my move gen is really fast... then comes Vincent... some hours coding brings me to 7M moves... and at this point I had no idea how to get faster... but it seems to be never over... I think also for Quark there is still much to improve here... when I only think about Vincents number... :)
