How AlphaZero has rewritten the rules of gameplay on its own


David Silver invented something that might be more inventive than he is. Silver was the lead researcher on AlphaGo, a computer program that learned to play Go--a famously tricky game that exploits human intuition rather than clear rules of play--by studying games played by humans. Silver's latest creation, AlphaZero, learns to play board games including Go, chess, and Shogu by practicing against itself. Through millions of practice games, AlphaZero discovers strategies that it took humans millennia to develop. So could AI one day solve problems that human minds never could?
