Early in the film "A Beautiful Mind,"
the mathematician John Nash is seen sitting in a Princeton court- yard, hunched
over a playing board covered with small black and white pieces that look like
pebbles. He was playing Go(围棋), an ancient Asian game. Frustration at losing
that game inspired the real Nash to pursue the mathematics of game theory,
research for which he eventually was awarded a Nobel Prize. In recent years, computer experts, particularly those specializing in artificial intelligence, have felt the same fascination and frustration. Programming other board games has been a relative snap. Even chess has succumbed to the power of the processor. Five years ago, a chess-playing computer called "Deep Blue" not only beat but thoroughly humbled Garry Kasparov, the world champion at that time.
