| has gloss | (noun) an equivalent given in return tit for tat |
| has gloss | eng: Tit for tat is an English saying meaning "equivalent retaliation". It is also a highly effective strategy in game theory for the iterated prisoners dilemma. It was first introduced by Anatol Rapoport in Robert Axelrods two tournaments, held around 1980. 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 similar to reciprocal altruism in biology. |

| has gloss | deu: Tit for Tat (engl. Redewendung, auf deutsch „wie du mir, so ich dir“), ist eine durch Robert Axelrods Buch Die Evolution der Kooperation bekannt gewordene Strategie für ein Spiel im Sinne der Spieltheorie. Sie bezeichnet eine Variante der Verhaltensregel „Auge um Auge, Zahn um Zahn: Tue anderen so, wie sie dir getan haben“. Dieses Teilzitat aus dem Alten Testament wird meist als Anweisung an das Opfer oder seine Vertreter aufgefasst, dem Täter Gleiches mit Gleichem „heimzuzahlen“. Bereits in den sechziger Jahren wurde die Strategie des „Tit for Tat“ von Anatol Rapoport (Universität Toronto) erfunden. |

| has gloss | zho: 以牙還牙（Tit for tat）是一個用於博弈論的重覆囚徒困境（Reiterated Prisoner's Dilemma）非常有效的策略。這策略最先由数学家阿納托·拉普伯特（Anatol Rapoport）提出，並在密歇根大學社會學家羅伯特·阿克塞爾羅（Robert Axelrod）有關囚徒困境的研究中擊敗其他方法，脫穎而出，成為解決囚徒困境的最佳策略 。 概述 這一策略有兩個步驟： #第一個回合選擇合作 #下一回合是否選合作要看上一回對方是否合作，若對方上一回背叛，此回合我亦背叛；若對方上一回合作，此回合繼續合作 以牙還牙策略有四個特點： #友善：以牙還牙者開始一定採取合作態度，不會背叛對方 #報復性：遭到對方背叛，以牙還牙者一定會還擊作出報復 #寬恕：當對方停止背叛，以牙還牙者會原諒對方，繼續合作 #不羨慕對手：以牙還牙者個人永遠不會得到最大利益，整個策略以全體的最大利益為依歸 在眾多策略中，以牙還牙是最有效的，曾連續數年擊敗由計算機科學家，經濟學家和心理學家等團隊所提出的策略。博弈論者儘管沒有實質證據，但他們認為以牙還牙是最佳的策略。 |
