Abstract
Biological organisms have various mechanisms of coping with the dynamical environments in which they live. Recent papers in computational biology show that individuals reside in different regions of neutral networks according to environmental variation. It has been also reported in several studies that there can exist neutral networks in binary-coded GAs. This work investigated evolutionary dynamics of GAs in dynamical environments with neutrality using a simple model. The evolutionary dynamics observed were consistent with those observed in the experiments of computational biology, confirming that the genotype distributions change depending on the rates of environmental variation as well as mutation.
