Re: Crafty Transpostion Table Question

SImple. This is the "lockless hashing" idea for parallel search. The issue is that different threads can store into the same hash table address at approximately the same time. There are two 64 bit values, the signature (A) and the score/etc (B). If two processors try to store at the same time, you ...

Do you mean 64 bit integer? In VC6.0 we can declare int64_t or LONG LONG.

I can develop most of chess jobs, from engine to GUI, using only VC6.0. However, it is too "old" to continue to use.

Re: Visual C++ 6.0 vs 2008?

Thanks all. Now it is clear to me. I will use VS2008. I guess some my friends "hate" VS200x because they use it for C# and compare with Java IDEs.

BTW, does anyone compare VS200x with gcc (in Windows)? Any change for gcc (in term of performance)?

Visual C++ 6.0 vs 2008?

I have just been back to chess hobby after a while and have a "silly" question: which version of Visual Studio - 6.0 or 2008 is better for chess, at least for chess speed?

(I confuse because some my friends still prefer 6.0 than 2008).

Thanks for your helps.

Re: A good time to broadcast a Xiangqi tourney?

Current XBoard / WinBoard is pretty good at implementing the Asia rules. If it is not perfect yet, I could fix it easily, You are expert!!!!!! if the ambiguity of the Asia rules could be clarified. The Asia rules are mainly specified through examples, and of some key dilemmas there are just no exam...

Re: A good time to broadcast a Xiangqi tourney?

That would be cool. I should add support to ChessV before the event. Wouldn't be difficult (to get it to play a reasonable game - making a strong engine is, of course, much more difficult.) To play a "simple" game, yes, you are right. But for a reasonable game - I think not easy. Different from (no...
