I'd be interested to hear, too. Øystein and I made little progress trying to
train the nets using TD training, supervised learning against the rollout
database, or a combination of both. Any gains we made were marginal, at best.
Øystein did a lot of work on speed improvements, and had some success with
that. I don't know if they could easily be integrated back into gnubg, though.

What training approach have you been using, if you don't mind elaborating?
