The talk is based on the 2005 paper by Sergiu Hart in which it is shown that a large class of simple rules of behavior, called adaptive heuristics, when used in repeated games, can generate rational behavior in the long run. They are based on natural regret measures, and may be viewed as a bridge between rational and behavioral viewpoints. Taken together, the results presented in the paper establish a solid connection between the dynamic approach of adaptive heuristics and the static approach of correlated equilibria of a game, a set more general than that of Nash equilibria of the game.
