Tit for tat cooperates initially and then repeats the opponent's previous action. Two such players cooperate forever without mistakes under this initial convention. It retaliates against defection and returns to cooperation after the opponent cooperates.
"Tit for tat" is a strategy used in game theory, specifically in the context of repeated games, such as the Iterated Prisoner's Dilemma. The strategy involves players responding to each other's actions by reciprocating in kind. If one player cooperates, the other player will also cooperate in the next round. Conversely, if one player defects or betrays, the other player will do the same in the next round.
