We characterize the class of symmetric two-player games in which tit-for-tat cannot be beaten even by very … sophisticated opponents in a repeated game.

Equilibrium notions for games with unawareness in the literature cannot be interpreted as steady-states of a learning … process because players may discover novel actions during play. In this sense, many games with unawareness are ''self … interpreted as steady-state of both a discovery and learning process. …

We test whether subjects try to influence those … and that all learning algorithms are subject to exploitation with the notable exception of imitation. The experiment was …

Recently there has been much theoretical and experimental work on learning in games. However, learning usually means … learning about the strategic behavior of opponents rather than learning about the game as such. In contrast, here we report on …
