I assume your assumption is wrong. IIRC in an earlier paper there was an input to indicate who's on. It is much simpler to present the position from the point of the moving player, because the net has to learn less. I'm not that familiar with the gnubg code, but I think they do it in this way, so you can't just turn the perspective. ciao Frank _______________________________________________ Bug-gnubg mailing list Bug-gnubg@gnu.org https://lists.gnu.org/mailman/listinfo/bug-gnubg
