ABSTRACT
The Prisoner’s Dilemma game (PD) models the decision problem of two players, each of whom must decide between two strategies, cooperate (C) and defect (D). There are four possible outcomes, and each player evaluates the pay-offs in the following order: T>R>P>S, where, for example, S is the pay-off to a player who cooperates when the other defects (Figure 25.1).
