![]() ![]() Last year, researchers at DeepMind, a subsidiary of Alphabet, developed a program capable of beating one of the world’s best Go players. This end-game analysis is computationally very challenging, and is performed during each game at the Pittsburgh Supercomputing Center, a facility operated by CMU and the University of Pittsburgh.Īdvances in machine learning and AI have seen a number of superhuman game playing programs emerge recently. This includes a new equilibrium approximation technique, Sandholm says, as well as several new methods for analyzing possible outcomes as cards are revealed at later stages of a game. ![]() He explains that Libratus uses several new advances to achieve such a high level of play. Last year, Sandholm led the development of a previous poker-playing program, called Claudico, which was soundly beaten in a match against several professional poker players. ![]() If you never bluff, you are not a good player. If you always bluff, you are not a good player. Game theory tells you how to randomize your play in a way that is, in a sense, optimal.” “This also results in a need to be unpredictable. “Whether a move is good or not depends on things you cannot observe,” says Vincent Conitzer, a professor at Duke University who teaches AI and game theory. ![]()
