Subject: Rybka's analysis is scanty

Author: William Penn

Date: 08:50:42 12/09/05

Rybka's analysis is fairly short to begin with, compared to most other engines.
It reaches its maximum after a few seconds, then it decreases at longer times.
For example here's an analysis of a position in infinite mode using the Shredder
Classic GUI. After 3 hours it is already showing a decrease of move information,
which decreases even further after 10 hours. The specific position doesn't
matter. I see this same pattern when analyzing any position for a long time.

This is Rybka *B*E*T*A*. Also, it is primarily a "playing" engine Ed Murak 09:09:35 12/09/05
