Re: Operating System

I know there is a selection biais in asking this question here, but just wondering what fellow chess programmers use MacOS (Intel) for daily use and development. I'm stuck at 10.6 because I still use some software from the PowerPC era (most notably Excel). For the next macbook I will buy that again...

Re: How about we settle the WCCC argument?

A lot of development is done my many teams in book learning algorithms and book preparation. IMO booking is an essential part of a WCCC. I perceive a lot of dogmatic thinking in the replies to my simple description of how the TCEC tournament became the most successful tournament of the past 2 years...

Re: How about we settle the WCCC argument?

4) Played with a fixed opening book or set of starting positions selected for the tournament, so that the competition doesn't degenerate in an opening book war. For maximum fairness also play every position with reversed colors. A lot of development is done my many teams in book learning algorithms...

Re: How about we settle the WCCC argument?

2) Played on powerful, uniform hardware so that the competition is fair to every engine (no doping!) and doesn't degenerate into a "cluster war". The problem is there are programs out there that perform differently on different hardware. The only real fair way to play would be on a single core syst...

Re: How about we settle the WCCC argument?

I can only answer that for myself, and the answer is: none whatsoever. Of course, *nobody* wants to see a tournament with 20 Houdini's. As long as the debate is presented as a choice between two undesirable extremes - the "ICGA" approach and the "Skinner" approach - nothing useful will come out of ...

Re: 40x(2) v Houdini 2.0c Has Ended! FINAL RESULTS!

Houdini 2.0c x64 vs. Engine 40x(2) - The Battle has ended! 40x(2) held his own thru game 718. And had actually cut Houdini's lead from 49 games to 39 games. From there to game 880- Houdini was able to make those 10 games back up. But games 881 thru 1000 Houdini went on one of the runs that, well......

Re: how to measure frequency of hash collisions.

Honestly, when I saw the problem posed I was suggesting a good way to accurately estimate the hash collision rate, none of the suggestions posted on this thread can judge the quality of the Zobrist hashing because they all require separate verification bits and the method falls apart no matter what...

Re: how to measure frequency of hash collisions.

Is there a way to directly measure the number of hash collisions (not its effect). I was thinking of storing the fen along with the hash key in transposition table entry, so that if the signatures match but the fens don't it would be collision. Is there a better way ? Edit: Right after I write this...

Re: World Computer Chess Championship ?

Ok this arrogant and fossilized organization called ICGA really made me get angry and I looked a bit in their site to know a bit more about them. Apart that it really seems "dead and buried", last interesting content is years ago old, I was really impressed by what they call: "World Computer Chess ...
