kn/s comparisons with different chess engines - 2008/04/25 23:22
Why does some chess engines go slower than others? For example, fritz 11 seems to run at 1800 or even 2200 kn/s on my quad core system while rybka 2.3.2 MP only runs at 150-200 kn/s.
I have read that some engines spend lots of time analyzing the quality/strength of a position or line rather than analyzing a bunch of bad moves... but even still, Fritz's depth ends up being 2 entire moves more (which is quite massive when you think about the exponential time involved in calculating 2 moves deeper than another engine).
So what is Rybka's problem?
