also can u post the experiment 79 settings here too please as well?
SCORE OFFSET MILLIPAWNS = ??
ROOK ENDGAME PENALTY MILLIPAWNS = ??
BISHOPS ARE OPPOSITE COLORED PENALTY MILLIPAWNS = ??
OPPOSITE COLORED BISHOPS ENDGAME PENALTY MILLIPAWNS =??
ROOK ENDGAME SCALING = 100
would be better if someone had a picture of the 4.1 settings box with the experiment 79 settings put in so i can see and make sure im doing right.. thanks in advance..
> SCORE OFFSET MILLIPAWNS =
Allows the engine to avoid draws in analysis if it seems them near the root (using a positive number). Or assuming the opponent wants to avoid draw (using a negative number.) Useful when you're analyzing positions that are a sea of 0.00s and you want to know more differences on the moves, and also because in the process Rybka would prune more drawn positions and build a more useful tree.
> ROOK ENDGAME PENALTY MILLIPAWNS = ??
Sometimes, Rybka assigns a winning score for positions that are draw in rook endgames (both sides with one rook and no minor pieces), this can change that by adding penalties to such positions (actually, Vas claims they're not drawish, but are to be avoided because it's harder to beat weaker opponents in them).
>BISHOPS ARE OPPOSITE COLORED PENALTY MILLIPAWNS = ??
The same, but for positions where each side has only one Bishop, and they're on opposite colors.
>OPPOSITE COLORED BISHOPS ENDGAME PENALTY MILLIPAWNS =??
The same, but for endgames.
>ROOK ENDGAME SCALING = 100
Allows you to scale down the score towards 0 in rook endgames.
I think Vas did a little more work to the piece weights before the 4.1 release.
After 1000 3'+2" games of R4.1 default vs R4.1 with R4 advanced settings x10
the settings are weakening the engine.
better default values.

I'm lovin' it

maybe rybka is soo generous to allow the opponent to 'live' to 2 moves more...and we never thought about that possibility
