Unexploitable games and unbeatable strategies
Masahiko Ueda
Imitation is simple behavior which uses successful actions of others in order to deal with one's own problems. Because success of imitation generally depends on whether profit of a…
Necessary and Sufficient Condition for the Existence of Zero-Determinant Strategies in Repeated Games
Masahiko Ueda
Zero-determinant strategies are a class of memory-one strategies in repeated games which unilaterally enforce linear relationships between payoffs. It has long been unclear for wha…
Unbeatable Tit-for-Tat as a Zero-Determinant Strategy
Masahiko Ueda
Tit-for-Tat strategy is a strategy in repeated two-player symmetric games which imitates the previous action of the opponent. We show that the Tit-for-Tat strategy is a zero-determ…
Memory-two strategies forming symmetric mutual reinforcement learning equilibrium in repeated prisoners' dilemma game
Masahiko Ueda
We investigate symmetric equilibria of mutual reinforcement learning when both players alternately learn the optimal memory-two strategies against the opponent in the repeated pris…
