A non-exponential technique that leads to arbitrary playing strength?
A good alpha/beta searcher does not replace "smarts" in a program, it supplements it. It would have to have some kind of "reading" at end nodes and dead stone analysis. It's a non-trivial problem - but it has nothing to do with alpha/beta. You never specifically answered Petr either. You attacked alpha/beta and never presented an alternative. One last important point. It's not a "bad" thing that Go is exponential. It's exponential in Chess too but it doesn't follow that this makes it infeasible. Otherwise it would be infeasible for Chess too. - Don > _______________________________________________ > computer-go mailing list > computer-go@computer-go.org > http://www.computer-go.org/mailman/listinfo/computer-go/ > > _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
