Thank you. GTFT Rules:

>Start with cooperation: The first move is always cooperation, regardless of the opponent's move. This establishes goodwill and creates a cooperative environment.
>
>Reciprocate cooperation: If the opponent cooperates in the previous round, then reciprocate by cooperating in the current round.
>
>Forgive one-time defections: If the opponent defects in a single round, forgive the defection and continue to cooperate in the subsequent rounds.
>
>Punish repeated defections: If the opponent repeatedly defects, then retaliate by defecting in the current round, but then return to cooperation if the opponent cooperates in the subsequent round.
>
>Be clear: Communicate your strategy and intentions clearly to your opponent to avoid misunderstandings and build trust.

​

>Studies have shown that GTFT can outperform TFT in certain situations where the costs of defection are high, and there is a high likelihood of occasional mistakes or misunderstandings. GTFT can also help to prevent "death spirals" of mutual defection that can occur in TFT when both players defect repeatedly.
