What is a zero-determinant strategy?

Abstract. Zero-determinant (ZD) strategies are a novel class of strategies in the repeated prisoner’s dilemma (RPD) game discovered by Press and Dyson. This strategy set enforces a linear payoff relationship between a focal player and the opponent regardless of the opponent’s strategy.

What is determinant strategy?

Zero-determinant strategies are a new class of probabilistic and conditional strategies that are able to unilaterally set the expected payoff of an opponent in iterated plays of the Prisoner’s Dilemma irrespective of the opponent’s strategy (coercive strategies), or else to set the ratio between the player’s and their …

What is trembling hand trigger strategy?

A trembling hand perfect equilibrium is an equilibrium that takes the possibility of off-the-equilibrium play into account by assuming that the players, through a “slip of the hand” or tremble, may choose unintended strategies, albeit with negligible probability.

What is the most useful tactic in the game of chicken?
