Dynamics of the Environment for Adaptation in Static Resource Models

摘要

We measure the environment that is relevant to a population's adaptation as the information-theoretic uncertainty of the distribution of local environmental states that the adapting population experiences. Then we observe the dynamics of this quantity in simple models of sensory-motor evolution, in which an evolving population of agents live, reproduce, and die in a two-dimensional world while competing for resources. Although the distribution of resources is static, the agents' evolution creates a dynamic environment for adaptation.
