The prisoners dilemma is a standard example of a game analyzed in game theory that shows why two completely rational individuals might not cooperate, even if it appears that it is in their best interests to do so. It was originally framed by Merrill Flood and Melvin Dresher working at RAND in 1. Albert W. Tucker formalized the game with prison sentence rewards and named it, prisoners dilemma Poundstone, 1. Two members of a criminal gang are arrested and imprisoned. Each prisoner is in solitary confinement with no means of communicating with the other. The prosecutors lack sufficient evidence to convict the pair on the principal charge. They hope to get both sentenced to a year in prison on a lesser charge. Simultaneously, the prosecutors offer each prisoner a bargain. Each prisoner is given the opportunity either to betray the other by testifying that the other committed the crime, or to cooperate with the other by remaining silent. The offer is If A and B each betray the other, each of them serves 2 years in prison. If A betrays B but B remains silent, A will be set free and B will serve 3 years in prison and vice versaIf A and B both remain silent, both of them will only serve 1 year in prison on the lesser chargeIt is implied that the prisoners will have no opportunity to reward or punish their partner other than the prison sentences they get, and that their decision will not affect their reputation in the future. Because betraying a partner offers a greater reward than cooperating with them, all purely rational self interested prisoners would betray the other, and so the only possible outcome for two purely rational prisoners is for them to betray each other. The interesting part of this result is that pursuing individual reward logically leads both of the prisoners to betray, when they would get a better reward if they both kept silent. In reality, humans display a systemic bias towards cooperative behavior in this and similar games, much more so than predicted by simple models of rational self interested action. A model based on a different kind of rationality, where people forecast how the game would be played if they formed coalitions and then maximized their forecasts, has been shown to make better predictions of the rate of cooperation in this and similar games, given only the payoffs of the game. An extended iterated version of the game also exists, where the classic game is played repeatedly between the same prisoners, and consequently, both prisoners continuously have an opportunity to penalize the other for previous decisions. If the number of times the game will be played is known to the players, then by backward induction two classically rational players will betray each other repeatedly, for the same reasons as the single shot variant. In an infinite or unknown length game there is no fixed optimum strategy, and prisoners dilemma tournaments have been held to compete and test algorithms. The prisoners dilemma game can be used as a model for many real world situations involving cooperative behaviour. In casual usage, the label prisoners dilemma may be applied to situations not strictly matching the formal criteria of the classic or iterative games for instance, those in which two entities could gain important benefits from cooperating or suffer from the failure to do so, but find it merely difficult or expensive, not necessarily impossible, to coordinate their activities to achieve cooperation. Strategy for the prisoners dilemmaeditBoth cannot communicate, they are separated in two individual rooms. The normal game is shown below Prisoner BPrisoner APrisoner B stays silentcooperatesPrisoner B betraysdefectsPrisoner A stays silentcooperatesEach serves 1 year. Prisoner A 3 years. Prisoner B goes free. Prisoner A betraysdefectsPrisoner A goes free. Prisoner B 3 years. Each serves 2 years. It is assumed that both understand the nature of the game, and that despite being members of the same gang, they have no loyalty to each other and will have no opportunity for retribution or reward outside the game. Regardless of what the other decides, each prisoner gets a higher reward by betraying the other defecting. The reasoning involves an argument by dilemma B will either cooperate or defect. If B cooperates, A should defect, because going free is better than serving 1 year. If B defects, A should also defect, because serving 2 years is better than serving 3. So either way, A should defect. Parallel reasoning will show that B should defect. Because defection always results in a better payoff than cooperation, regardless of the other players choice, it is a dominant strategy. Mutual defection is the only strong Nash equilibrium in the game i. The dilemma then is that mutual cooperation yields a better outcome than mutual defection but it is not the rational outcome because from a self interested perspective, the choice to cooperate, at the individual level, is irrational. Generalized formeditThe structure of the traditional Prisoners Dilemma can be generalized from its original prisoner setting. Suppose that the two players are represented by the colors, red and blue, and that each player chooses to either Cooperate or Defect. If both players cooperate, they both receive the reward R for cooperating. If both players defect, they both receive the punishment payoff P. If Blue defects while Red cooperates, then Blue receives the temptation payoff T, while Red receives the suckers payoff, S. Similarly, if Blue cooperates while Red defects, then Blue receives the suckers payoff S, while Red receives the temptation payoff T. This can be expressed in normal form Canonical PD payoff matrix.

STPPand to be a prisoners dilemma game in the strong sense, the following condition must hold for the payoffs T R P SThe payoff relationship R P implies that mutual cooperation is superior to mutual defection, while the payoff relationships T R and P S imply that defection is the dominant strategy for both agents. Special case Donation gameeditThe donation game8 is a form of prisoners dilemma in which cooperation corresponds to offering the other player a benefit b at a personal cost c with b c. Defection means offering nothing. The payoff matrix is thus. Red. Blue. Cooperate. Defect. Cooperateb cb cb c. Defect cb. 00. Note that 2. R TSdisplaystyle 2. R TS i. e. The donation game may be applied to markets. Suppose X grows oranges, Y grows apples. The marginal utility of an apple to the orange grower X is b, which is higher than the marginal utility c of an orange, since X has a surplus of oranges and no apples. Similarly, for apple grower Y, the marginal utility of an orange is b while the marginal utility of an apple is c. If X and Y contract to exchange an apple and an orange, and each fulfills their end of the deal, then each receive a payoff of b c. If one defects and does not deliver as promised, the defector will receive a payoff of b, while the cooperator will lose c. If both defect, then neither one gains or loses anything.
