WebSpecifically, it has been known for more than 20 years that when all players seek to minimize their internal regret in a repeated normal-form game, the empirical frequency of play converges to a normal-form correlated equilibrium.

WebAbstract. We consider the problem of simultaneous learning in stochastic games with many players in the finite-horizon setting. While the typical target solution for a stochastic game is a Nash equilibrium, this is intractable with many players. We instead focus on variants of correlated equilibria, such as those studied for extensive-form ... WebAn alternative deﬁnition of correlated equilibria for extensive games with perfect recall may be closer in spirit to behavior strategies. Behavior strategies sufﬁce for Nash equilibria, and are represented in the sequence form. Forges and von Stengel (2001) propose the “extensive form correlated equilibrium” as a such concept. In ... psychotherapy office decorWebFor common notions of correlated equilibrium in extensive-form games, computing an optimal (e.g., welfare-maximizing) equilibrium is NP-hard.

WebChicken. In game theory, a correlated equilibrium is a solution concept that is more general than the well known Nash equilibrium. It was first discussed by mathematician Robert Aumann in 1974. [1] [2] The idea is that each player chooses their action according to their private observation of the value of the same public signal.
