CMU Group Describes "Superhuman" Poker AI in Science
Libratus Used Pittsburgh Supercomputing Center's Bridges to Formulate Its Strategy in Contest with Best Human Players
By Byron Spice
In a paper published online yesterday by the journal Science, Tuomas Sandholm, Carnegie Mellon professor of computer science, and Noam Brown, a PhD student in the Computer Science Department, detail how their AI achieved superhuman performance at Heads-Up, No-Limit Texas Hold'em poker. "Libratus" beat four of the world's best human players by breaking the game into computationally manageable parts and, based on its opponents' game play, fixing potential weaknesses in its strategy during the competition. Libratus used PSC's Bridges system to play and to formulate its strategy.
