of gnubg at different plies. The last large scale study (done to compare the
existing bots to the new extreme gammon), is resumed here:
http://www.extremegammon.com/studies.aspx
Checker play is fine, error goes down as plies go up.
However, for cube actions, the situation is very strange:
3ply does much better than 2ply and 4ply on missed doubles and wrong takes.
But 3ply does terribly worse than 2ply and 4ply on wrong doubles and
wrong passes.
It has always been accounted to the so called "odd-even" effect, but
no other bot
seems to be affected as much as gnubg.
MaX.
