第162行： − 模因算法的一些变化涉及到在不同层次的选择之间的交替。这些都与鲍德温效应有关，当作用于表型（如学习）的过程影响基因型水平上的选择时，鲍德温效应就会产生。在这个意义上，鲍德温效应在全局搜索（基因型）和局部搜索（表型）之间交替。 + 第173行：
第173行： − 双相演化与自组织临界现象有关。两者都涉及关键阶段变化促进系统内适应和组织的过程。然而，SOC与DPE在几个基本方面不同。在SOC下，系统的自然状态是处于临界状态；在DPE中，系统的自然状态是非临界状态。在SOC中，扰动的大小遵循幂律；在DPE中，扰动的分布不一定相同。在SOC中，一个系统不一定要经历其他过程；在DPE中，不同的过程（如选择和变化）在两个阶段中运行。+

Some variations on the memetic algorithm involve alternating between selection at different levels. These are related to the Baldwin effect, which arises when processes acting on phenotypes (e.g. learning) influence selection at the level of genotypes. In this sense, the Baldwin effect alternates between global search (genotypes) and local search (phenotypes).

Dual phase evolution is related to the well-known phenomenon of self-organized criticality (SOC). Both concern processes in which critical phase changes promote adaptation and organization within a system. However, SOC differs from DPE in several fundamental ways. Under SOC, a system's natural condition is to be in a critical state; in DPE a system's natural condition is a non-critical state. In SOC the size of disturbances follows a power law; in DPE disturbances are not necessarily distributed the same way. In SOC a system is not necessarily subject to other processes; in DPE different processes (e.g. selection and variation) operate in the two phases.

双相演化与著名的自组织临界现象有关。两者都涉及关键相变促进系统内适应和组织的过程。然而，SOC与DPE在几个基本方面不同。在SOC下，系统的自然状态是处于临界状态；在DPE中，系统的自然状态是非临界状态。在SOC中，扰动的大小遵循幂律；在DPE中，扰动的分布不一定相同。在SOC中，一个系统不一定要经历其他过程；在DPE中，不同的过程（如选择和变化）在两个阶段中运行。
