进化和学习之间的相互作用被称为鲍德温效应，是一个两步进化的场景，通常是由学习的收益和成本之间的平衡引起的。然而，人们对这些平衡在复杂环境中的动态演变知之甚少。我们的目的是提供一个新的洞察学习的好处和成本，通过专注于定量进化的表型可塑性的假设上位相互作用。为此，我们构建了一个数量性状的进化模型，通过使用考夫曼的NK适应度景观的扩展版本。表型可塑性被引入到我们的模型中;每个表型是否是可塑的是遗传定义的，并且可塑的表型可以通过学习来调整。仿真结果清楚地表明，学习角色的急剧变化导致三步进化通过鲍德温效应，也导致遗传鲁棒性对突变的进化。我们还概念化四个不同的角色，通过使用一个爬山的图像上的健身景观的人口学习。
The interaction between evolution and learning called the Baldwin effect is a two-step evolutionary scenario caused by the balances between benefit and cost of learning in general. However, little is known about the dynamic evolution of these balances in complex environments. Our purpose is to give a new insight into the benefit and cost of learning by focusing on the quantitative evolution of phenotypic plasticity under the assumption of epistatic interactions. For this purpose, we have constructed an evolutionary model of quantitative traits by using an extended version of Kauffman's NK fitness landscape. Phenotypic plasticity is introduced into our model; whether each phenotype is plastic or not is genetically defined, and plastic phenotypes can be adjusted by learning. The simulation results clearly show that drastic changes in roles of learning cause three-step evolution through the Baldwin effect and also cause the evolution of genetic robustness against mutations. We also conceptualize four different roles of learning by using a hill-climbing image of a population on a fitness landscape.
