Prisoner's Dilemma

From Wikipedia, the free encyclopedia

Will the two prisoners cooperate to minimise total loss of liberty or will one of them, trusting the other to cooperate, betray him so as to go free?

The prisoner's dilemma is a type of non-zero-sum game. In this game theory problem, as in many others, it is assumed that each individual player is trying to maximise his own advantage, without concern for the well-being of the other player.
