| 最后一个示例指出了纳什均衡与进化均衡策略之间的重要区别。纳什均衡是在策略集(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均衡与进化均衡策略之间的重要区别。纳什均衡是在策略集(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 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'''<font color="#ff8000"> 群体遗传学Population Genetics</font>''','''<font color="#ff8000"> 动力学系统Dynamical System</font>'''或'''<font color="#ff8000"> 演化博弈论Evolutionary Game Theory</font>'''的一部分。现在称为'''<font color="#ff8000"> 收敛稳定性Convergent Stability</font>'''。
