The results from the UCT-in-UCT playouts could be fed back to the main UCT tree (in which case no playouts are "lost"), with the result from the meta-playout having a stronger weighting. > Valkyria scales between 150 Elo between 5 and > 10 playouts against Fuego 0.3.2 using 200 playouts.

The idea to make very very heavy playouts is a bit contradictory to this. Something like libego running a 50kpps would get 100nps in your example. It may be enough. -- GCP _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
