We introduce the concept of deformed zero-determinant strategies in repeated games. We then show that Tit-for-Tat strategy in repeated prisoner's dilemma game is a deformed zero-determinant strategy, which unilaterally equalizes the probability distribution functions of payoffs of two players.

以牙还牙策略作为重复博弈中变形的零决定性策略

我们在重复博弈中引入了变形零行列式策略的概念。然后我们证明了重复囚徒困境博弈中的以牙还牙策略是一种变形的零行列式策略，它单边均衡了两个参与者的收益的概率分布函数。
