9、为非合作博弈均衡，是博弈论的一个重要术语，以约翰纳什命名。在一个博弈过程中，无论对方的策略选择如何，当事人一方都会选择某个确定的策略，则该策略被称作支配性策略。如果两个博弈的当事人的策略组合分别构成各自的支配性策略，那么这个组合就被定义为纳什均衡。一个策略组合被称为纳什均衡，当每个博弈者的均衡策略都是为了达到自己期望收益的最大值，与此同时，其他所有博弈者也遵循这样的策略。,2020/7/24,Unit One Mathematics,25,Prisoners Dilemma,The Prisoners Dilemma is one of the best-known models in gam
