I do agree with Alain that beginners mix too little and random
players too much.
I am most intrigued with the recent results from Dave Hillis,
where he shows what I have been calling a move towards a
"transition temperature" with a selected set of heuristics in
the playout. When he is willing to go public with the details
of the correspondence between the heuristics and the scaling
behavior we will all know more.
In the mean time, I am completely hobbled by my physics
background and knowledge. I am too stuck with thinking
about some kind of energy function to make progress the
way Dave is. But I am working towards putting aside any
formal sense of what I think is correct and just trying and
testing like Dave is ... a sort of random experimental view
where I just try stuff and see what happens. Perhaps that
will eventually lead to a new insight.
Cheers,
David

But the whole stuff is rather coherent in my mind.
Then I envy you. I have been trying to bring what I know
about MC in physics together with Go for over 20 years,
and I get tripped up every time by temperature. I know
how to deal with it properly in the physics, but I still have
no idea at all about how to cool the MC Go simulations.
The concept of temperature as used in CGT (combinatorial
game theory) has not helped me.
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?
Yes :)
Beginners do not mix enought, random players mix too much.
Alain
