I am surprised by how often an MC bot wins by exactly 0.5 point. It's almost as if it is converging to a 0.5 victory. One way to look at this is that an MC program is all about consolidating just the amount of territory it needs to win. It will never go for a big win and doesn't associate extra goodness to a bigger win. It's much easier to win small so I guess it makes sense that really tiny victories are very common in MC programs. - Don Jason House wrote: > > > On 10/30/07, *Heikki Levanto* <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>> > wrote: > > This works surprisingly well, although there are some drawbacks. > Evaluating > positions this way prefers safe, solid groups.
