How many games did Critter lose against Houdini 1.5a in last 30 games?
I don't know if Mr. Vida will read this. I want to write some considerations. I had no time to watch the games, but numbers are saying us strategy=depth + resolve score drops=off is the best setting for running these kind of matches. Or, at least, it seems the most reliable.
After 100 full games, session file gets about 5% full, meaning it'd be 100% full after about 2000 games. One could raise file size, but I guess that could lower engine performance. To store pre-ending and ending positions is useless for learning purposes. Maybe, an UCI option which limits the number of plies of keeping learning active from a start position could help in keeping free space in the session file for more games.
I hope this test has been of some interest.
Maestro , the whole history of computers and computer chess is presented in my bunker ! I have even a very old PC working ( perfectly) with my dear 16 bit Windows 3.11 and many goodies !
