[computer-go] Re: Move Prediction and Strength in Monte-Carlo Go

[Rémi Coulom]

Hi,

I would like to confirm your experiments: I have noticed already that 
adding shapes of radius > 4 improves prediction a lot, but does not 
improve playing strength (from progressive widening).

Also, even worse than that, for a given set of features, the pattern 
urgencies computed by MM are not optimal. That is to say, it is possible 
to manually tweak urgencies and get a stronger program.

So, as Gian-Carlo puts it, optimizing a Go program is still black magic. 
There is no way to avoid playing games to measure playing strength.
