| 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。 | | 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 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. | | In an evolutionarily stable strategy, if all the members of a population adopt it, no mutant strategy can invade.

− | 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. | | In an evolutionarily stable state, a population's genetic composition is restored by selection after a disturbance, if the disturbance is not too large.

− | 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。
