Superhuman performance by artificial intelligence (AI) has been demonstrated in two-player, deterministic, zero-sum, perfect-information games such as chess, checkers , Hex, and Go .
Research using AI has broadened to include games with challenging attributes such as randomness, multiple players, or imperfect information. Randomness is a feature of dice games, and card games include the additional complexity that each player sees some cards that are hidden from others. These aspects more closely resemble real-world situations, and this research may thus lead to algorithms with wider applicability.
On page 885 of this issue, Brown and Sandholm (4) show that a new computer player called Pluribus exceeds human performance for six-player Texas hold'em poker.
