I think they are agressive mainly since killing big group is much surer way of victory than drawn-out close game, they want to maximize the advantage the quickest way possible. Also my collected anectodal evidence suggests MCTS might be actually quite lousy at counting score in tight games (at least on 19x19, and that fact makes a lot of sense to me) - I'm not completely sure of this though, did anyone do some extensive testing of modern MCTS on hard endgame problems? -- Petr "Pasky" Baudis A lot of people have my books on their bookshelves. That's the problem, they need to read them. -- Don Knuth _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
