Re: Derivatives are real programs too

I believe programs like Toga, Cyclone, StockFish, etc. should be recognized as legitimate engines and allowed entrance into major tournaments. These 'derivatives' are not the same as 'clones' (which can easily be produced by hacking the original executable with with a hex editor, or simply re-compi...

Re: Cyclone 2.1 released

This version incorporates Dann Corbit's contribution: a UCI 'Threads' option. His code enables setting the # of threads using the GUI, thus eliminating the need for 5 separately compiled executables (1-cpu, 2-cpus, 4-cpus, etc.) I tested it today, and it works well. It does not affect Cyclone's str...

Re: THINKER 5.3B - A VERY STRONG ENGINE !

my problem is that i see no information under arena. only if it moves i get a main-line. but not during computation. is there anything wrong with my setting ? Apparently it's a design decision. I guess it is the feature that receives the most complaints. But it plays like Anand anyway so I guess we...

Re: SSDF list: why Chessmaster is not tested anymore?

Last Chessmaster tested version is CM 9000. There`s no CM 10000 and no CM Challenge ("11000"). Why ? IMHO it must be tested, it is the #1 seller all over the world! Here in Brazil a full copy of CM 10000 sells at US$15 only - much cheaper than Rybka or Fritz. It is very difficult to test it in the ...

Re: Glaurung and hyperthreading?

who have already try glaurung with hyperthreading, i am curious of this :-) have you stats? I have not tried it but I have never seen any chess engine get a big benefit from hyperthreading. It seems to me that the big benefit from hyperthreading would occur if you have a huge number of context swit...

Re: reasonable nps

Dr. Hyatt, Is there (as far as you know) a direct correlation (or any relationship) betwen NPS and strength? I'm often concerned if a change I make lowers NPS. I know that some engines are strong despite a low NPS. I also know that other engines acheive an extraordinarily high NPS (like Crafty) I h...

Re: THINKER 5.3B - A VERY STRONG ENGINE !

Yawn... another protocol war. UCI sucks. Despite your aversion to uci, it currently seems to be the most accepted protocol. I'm most appreciative of the wb2uci adaptors. :P Well, Windows is the most popular operating system. Tells you something, huh? ;) Don't get me wrong, the XB protocol isn't the...

Re: Stockfish 1.01 FIX A SERIOUS BUG

First impression: Stockfish looks really strong. It seems to outsearch everyone. And I am using my MS VC++ build. Jim's build will probably be quite a bit faster. I get extremely low kn/s counts here. Same for others? Not for me... I get Glaurung like nodecounts, as expected. E.g. I am getting 3.5 ...
