Hi Walt, On February 05, 2006 at 00:44:31, walt irvin wrote: > i wonder how similar nimzo is to hydra???? i wonder if u could speed the > search of nimzo up as fast as hydra would they get similar results,,,???? well, it's clear that Chrilly has taken his experience with Nimzo into the Hydra project. But I am very sure that there is a big difference between them, simply because you can do things in hardware you can't do in software and vice versa. Therefor I do not think that both would present the same lines and moves when searching to similar depth. Also I am quite sure that if you would find a single CPU which gives e.g. Nimzo 9 as many nodes per second as Hydra reaches on it's cluster, Nimzo 9 would win almost all games. Hardware has it's limitations, the search inside the hardware can't be nearly as effective as the search in the software. And also don't forget about the overhead a parallel search produces. Same nodes on a single is always better then the same amount of nodes on a parallel system. Also we do not have really an idea how strong Hydra is compared to other engines, there was not much competition lately. I doubt that it is really the strongest chess entity in the world. But of course that is my opinion. Like I believe that Deep Blue on '97 hardware would only play in 2nd Divison at WBEC. Greets, Thomas
