Tit for tat is a highly effective strategy in game theory for the iterated prisoner's dilemma. It was first introduced by Anatol Rapoport in Robert Axelrod's two tournaments, held around 1980. Based on the English saying meaning "equivalent retaliation" ("tit for tat"), an agent using this strategy will initially cooperate, then respond in kind to an opponent's previous action. If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not. This is equivalent to the concept of reciprocal altruism in the context of biology.
This strategy is dependent on four conditions that has allowed it to become the most prevalent strategy for the Prisoner's Dilemma:
*Unless provoked, the agent will always cooperate*
*If provoked, the agent will retaliate*
*The agent is quick to forgive*
*The agent must have a good chance of competing against the opponent more than once*.
