Re: Any update on Thinker 5.5?

I have no information on release date. All I know is that the developmental version (v5.56) currently holds top ranking on FICS while only running on an intel Q6600. Many of the Houdinis and Rybkas that it beats are running on 6-core i7's. I don't like how little Thinker outputs (no eval, no PV) but...

Re: Solving Chess

The problem is that you don't know what positions are "won" until you've found the solution. A few years back I theorized about storing positions only after a high-ply search yielded equal material. The assumption would be that the solution tree would be mostly comprised of materially-even positions...

What do you mean by "expertise"?

AMD Bulldozer Chess Benchmarks

Looks like there was a Fritz chess benchmark run on an engineering sample of a "Bulldozer" chip clocked at 3.2 Ghz. 8 threads = 14,197 kn/sec http://vr-zone.com/articles/purported-amd-bulldozer-benchmarks-leaked/12914.html This is roughly equivalent to a 6-threaded result an Intel i7-970, but of cou...

Tuning eval to minimize nodes searched

Can tuning the evaluation function cause more cut-offs and thus reduce nodes searched for a certain depth? I've often assumed that to properly tune eval, you'd need fixed depth matches, but this morning I thought that maybe a properly tuned evaluation function merely facilitates a faster search by r...

Re: 'K' Computer Now Fastest In The World

Something to note: these supercomputers are ranked by their floating point benchmarks. Its a little bit like measuring a GPU vs a CPU. I understand that these huge clusters are often fully capable running integer calcs, but certainly optimized for FLOPS. Its my experience that chess performance is m...

Speedup - Time to Ply - Stockfish

Just curious if anyone has speedup information for Stockfish. I recognize that there is information out there from Crafty, but has anyone run tests on Stockfish? Hopefully the current algorithms are achieving higher speedups than the ones of the mid 1990's... but for some reason I doubt that is the ...

Question for the Komodo Team

To be a little blunt, is the plan for Komodo to go commercial with an SMP version? I've seen many comments on this forum that indicate that those people believe the SMP version will cost money, but I can't find where someone has asked the question. I do recall a thread where Don was very vague, and ...

Re: Komodo 2.01 is out!

Great release!

Can Komodo play Chess960 (Fischer Random) correctly?

Have you thought about supporting it in the future?

Chess vs. Protein Folding

I was wondering if anyone has ever tried applying PVS/MTD(f)/Alpha-beta type searcher to the whole 'protein folding' problem? Really it all seems so similar to me. Going depth first, string some amino acids together using a 'legal move' generator based on physics, evaluate the resulting position bas...
