For purposes of discussion, let's say the bot takes a tactical snapshot once at the root node and then uses that information to help pick a move. It can apply it at the root, at internal nodes, at external nodes, or at the very end (maybe it decides this is an UCT-deceptive position and calls another algorithm). To keep a tight focus, I suggest ideas that involve calculating additional tactical information during the playouts themselves go into the ladder thread. So, what tactical information should be calculated, how should it be used, and yes how should it be stored? - Dave Hillis --- ________________________________________________________________________ More new features than ever.
