WebExtensive-form correlated equilibrium (EFCE) has been proposed as the natural extensive-form counterpart to normal-form correlated equilibrium. However, it was currently unknown whether EFCE emerges as the result of uncoupled agent dynamics. WebMar 14, 2024 · For team games, the two-sided column generation approach vastly outperforms standard column generation approaches, making it the state of the art algorithm when the parameter is large. Along the way we also introduce two new benchmark games: a trick-taking game that emulates the endgame phase of the card game bridge, and a …

It was first discussed by mathematician Robert Aumann in 1974.
