Poker: an artificial intelligence crushes the best professional players

The program, developed in part by Facebook, has won several Texas Hold'em poker games at six.

New confrontation and … New defeat of the man in front of the machine. This time, an artificial intelligence (I.A.) developed by Carnegie Mellon University, in collaboration with Facebook I.A., has crushed some of the best players in the world of Texas Hold'em Poker. In the first part of the experiment, published in the journal Science Thursday, July 11, I.A. Pluribus has played 5,000 hands against two professionals: Darren Elias, who holds the record for most World Poker Tour titles, and Chris "Jesus" Ferguson, winner of six World Series of Poker events. But if Pluribus – or rather its ancestor Libratus – had already won "one against one" in 2017, the second part of the experience, it is a real novelty. Because the algorithm has this time played 10,000 hands in several games with six players.

In all, he played and defeated thirteen professional players who have already won more than $ 1 million in competition. "Pluribus has achieved superhuman performances in multiplayer poker, which is a first in the field of artificial intelligence for decades," said Tuomas Sandholm, a professor of computer science at Carnegie Mellon, who developed Pluribus with his pupil Noam Brown. "Until now, artificial intelligence's strategic reasoning has been limited to duels, but this ability to beat five other players in such a complicated game opens up new opportunities for using AI to solve a wide variety of gameplay problems. real world, "he added. A feat particularly noteworthy because, unlike chess or Go, poker is a game in which players bluff and do not know the cards of their opponents, which involves much more complex calculations for the machine.
