According to the table above, there are three Pareto optimal points in the prisoner’s Dilemma game, which are 1. (Confess, Deny) - 2. (Deny, confess)- 3. (Deny, Deny). But the choice of the players is the point except for the Pareto optimal points. Players in prisoner’s Dilemma non - cooperative game will choose the Nash equilibrium that is (Confess, confess). (Confess, confess) strategy is the one that will minimize the win chance of opponent.
