David - using Alain's analogy about temperature being related to mixing,
isn't there a link with what Peter Drake calls the "proximity heuristic" in
the MC playouts? A completely random MC player may be "too hot" and one that
always plays next to already occupied points "too cold".  In between, it
should be possible to define a temperature parameter which controls how
close to the existing points a random MC playout happens.  You could then
test how strength varies with this "temperature" parameter.  Is this what
either of you had in mind?
