Re: Arena Time Forfeits

Yes, I know.
With an inc of 2 seconds, Arena.debug input to WB engines should never be less than 200, but it is.
UCI engines get the correct 2,000.

Arena forum post indicates it may be fixed in the 1.99B5 beta version.

I was using B4.

Arena Time Forfeits

It has been some time since I have used Arena. I am testing Tinker against a number of other engines at 1 min plus 2 sec increment, no pondering (on Q6600, Vistax64). It looks like nearly 10% of the games are time forfeits. Examination of the arena.debug file indicates an Arena issue. The time/otime...

Vista Premium x64 with Visual Studio 2008 Express Edition

Anyone using this combination?

If so, is downloading some SDK needed ?

Thanks

Terminator TV Series Computer Chess

FWIW, the episode last night featured computer chess quite a bit, albeit with typical Hollywood embellishments. Plot concept is CC type AI might lead to SkyNet.

Re: fractal null move

Perhaps you meant "factional" null move, which has been around for years. Fractals are something else entirely http://en.wikipedia.org/wiki/Fractals PS In the list of constraints, it looks like there must be more than 16 moves. This is often not the case. Instead, I would suggest testing the "other ...

Re: BitBoard Tests Magic v Non-Rotated 32 Bits v 64 Bits

Hi Brian, how fast is 64-bit with optimization off or a 64-bit debug version? Strange the the 32-bit magic is that fast with VS2003 despite 64-bit imul calls with up to three 32-bit imuls. I would have expected something like 20-30 seconds for 64-bit mode if you do a lot of 64-bit stuff which is li...

Re: Frustrations of a mediocre chess programmer. What next?

I've been working on and off (mostly off) on Tinker and prior incarnations since about 1970. While Tinker has been roughly a "middle" or "top half of bottom third" strength engine (I'm on the verge of a total rewrite), here are some things that are more incremental. First, put your engine up on ICC....

BitBoard Tests Magic v Non-Rotated 32 Bits v 64 Bits

I have been working on Tinker a bit lately and am trying to get back to 64 bit mode after initial experiments a few years ago. I am currently using an evaluation copy of Windows XP Pro x64 (free for 120 days) with the Visual Studio 2008 Beta2 (free for 200 some odd days). Hardware is an Opteron 246 ...
