Re: Rybka 1.0 source code

http://www.top-5000.nl/Fruit_vs_Fadden.htm Rick Fadden called it depthlimit. The bottom line is that Rybka 1.6.1 (April 19, 2004) has UCI and why would anyone copy something he already has? If you really have R1.6.1 (not sure how you would get it...), then please stop spreading misinformation about...

Re: A few general questions...

This seems all nonsense. The archetypal root search is RootSearch() { GenerateMoves(); firstMove = TRUE; for(depth = 1; depth < maxDepth; depth++) { SetAspirationWindow(); for(ALL_MOVES) { MakeMove(); score = -Search((firstMove ? -alpha-1 : -beta&#...

Re: Rounding

I think it's difficult to change the scale one you have committed to one. I imagine this is true for most people, but IMO this is because most people use inferior programming languages/development strategies. I prefer to have all tuned values in floating point, and have the actual fixed-point integ...

Re: Ed Schröder retires from ICGA.

Did you a favor and updated the page, I don't think you will like it. But you forced me. The thing you have to learn is to take responsibility for what you said in the past but is not convenient today. http://www.top-5000.nl/pst.htm When did Bob change his name to ICGA Bob? Nowhere on that page. I'...

Re: The near future of computer chess

Please, let the 20 year olds do their own talking, they tend to have big mouths anyway. If there are much left - they can and do vote with their feet, too. Yes, please do.
