最后一个示例指出了纳什平衡与进化均衡策略之间的重要区别。纳什平衡是在策略集(每个参与者的策略规范)上定义的,而进化均衡策略是根据策略本身定义的。进化均衡策略定义的平衡必须始终是对称的,因此其平衡点更少。

In population biology, the two concepts of an ''evolutionarily stable strategy'' (ESS) and an ''[[evolutionarily stable state]]'' are closely linked but describe different situations.

在种群生物学中,evolutional stable strategy 和进化稳定状态这两个概念紧密相连,但描述的情况却不同。

在种群生物学中,进化均衡策略(ESS)和进化稳定状态Evolutionarily Stable State这两个概念密切相关,但却描述了不同的情况。

In an evolutionarily stable strategy, if all the members of a population adopt it, no mutant strategy can invade. Once virtually all members of the population use this strategy, there is no 'rational' alternative. ESS is part of classical game theory.

在 evolutional stable strategy 中,如果一个种群的所有成员都采用它,那么任何变异策略都不能入侵。一旦几乎所有的人都使用这种策略,就没有理性的选择了。ESS 是经典博弈论的一部分。
+
在进化均衡策略中,如果所有种群的成员都采用它,那么任何突变策略都无法入侵。无形中只要所有成员都使用了这种策略,就不再有“理性”的选择。进化均衡策略是经典博弈论的一部分。

In an evolutionarily stable state, a population's genetic composition is restored by selection after a disturbance, if the disturbance is not too large. An evolutionarily stable state is a dynamic property of a population that returns to using a strategy, or mix of strategies, if it is perturbed from that initial state. It is part of population genetics, dynamical system, or evolutionary game theory. This is now called convergent stability.

在进化稳定状态下,如果干扰不太大,通过干扰后的选择恢复种群的遗传组成。进化稳定状态是种群的一个动态特性,当种群从初始状态受到扰动时,它会返回到使用策略或混合策略的状态。这是群体遗传学、动力系统或者进化博弈论的一部分。现在称之为收敛稳定性。

在稳定的进化状态下,如果干扰不太大的话,即使受到冲击,种群的基因组成通过策略选择同样能够进行恢复。而进化稳定状态是种群的动态特性,即使受到初始状态的干扰,该状态会通过使用策略或混合策略组进行恢复。它是群体遗传学,动力学系统或进化博弈论的一部分。现在称为收敛稳定性。

B. Thomas (1984) applies the term ESS to an individual strategy which may be mixed, and evolutionarily stable population state to a population mixture of pure strategies which may be formally equivalent to the mixed ESS.

托马斯(1984)将 ESS 一词应用于可能混合的个体策略,而将进化稳定的种群状态应用于纯策略的种群混合,这种混合策略在形式上等价于混合的 ESS。

托马斯B. Thomas(1984)将“进化均衡策略”这一术语应用于可混合的独立策略,并将“进化稳定种群状态”应用于采取纯策略的混合种群,该应用在形式上可能等同于混合的“进化均衡策略”。
