[Bug-gnubg] Questions on pruning net

[Ian Shaw]

1. When the pruning nets have finally selected a move, is that move
re-evaluated using the full nets at the relevant play, to give the best
possible evaluation of the equity?

2. How strong are the pruning nets in their own right? How do they
compare with 0-ply?

3. Might it be useful to use the pruning nets as a playing option lower
than "expert", rather than introduce noise? I can think of two potential
benefits. We might be able to get a really quick rollout - the current
sub-expert settings are not useful at all, I think. Secondly, the
pruning nets might have a more consistent playing style than the random
effects currently used. This may give a "better" game than we currently
have for lower level players.
