Re: Speedup with bitboards on 64-bit CPUs

[This is far faster at a K7 than crafty at a 64 bits chip. Vincent Ofcourse, you can say anything you want because we have no way of testing Crafty against your engine. May be you and Hyatt should do a 100 game online match at ICC at a decent time control. The statement makes no sense. That implies...

Re: winboard/ICC issue

I have also seen another strange thing on ICC. I will +noplay a player (so I can play another program and make sure the program does not automatically accept a game from them), but after a game, ICC will start another game with the last opponent. I have had to disconnect to just prevent an endless ...

Re: AMD64 Dual core

Greetings, Was curious, when AMD says a CPU is a 2 or 3ghz Dual core, does that mean each core is that speed or combined? Thought that was the truth, but noticed on my machine at work when I check /proc/cpuinfo it's actually 2 1ghz cores for a 2ghz AMD64. Maybe linux is interpretting it wrong, or t...

Re: avoidrep-pruning

It is not a big deal, but it might help in "no progress" and/or shuffle-positions, where pairwise "null-moves" to push "no progress" behind the horizon, gots faster refuted. But of course there are most likely other possibilities to shuffle around rather than immediate repetition of moves near the ...

Re: 10th aniversery of deep blue win: interesting news artic

The thing that most amazes me is that supposedly Kasparov claims he has never been able to look at the deep blue logs. Even though they were (and still are) available on the web. I could email 'em to him if he would shut that claim up. :) Those logs have a problem. The logs on the ibm web site have...

Re: a beat b,b beat c,c beat a question

Do you have a case when the following happened: 1)version X+1 of your program beat version X with a significant score. 2)version X+2 of your program beat version X+1 with a significant score. 3)version X of your program beat version X+2 with a significant score. If the answer is positive then what ...

Re: 10th aniversery of deep blue win: interesting news artic

It's a foregone conclusion that Deep Blue wasn't very strong, clearly weaker than today's top engines, and that Kasparov could have played much better. Psychology definitely played a large role in that match. "wasn't very strong" yet it blew away every program 10 years ago. Sort of a "self-contradi...
