Genetic Algorithms in Time-Dependent Environments
Christopher Ronnewinkel, Claus O. Wilke, Thomas Martinetz
The influence of time-dependent fitnesses on the infinite population dynamics of simple genetic algorithms (without crossover) is analyzed. Based on general arguments, a schematic…
Molecular Evolution in Time Dependent Environments
Claus O. Wilke, Christopher Ronnewinkel, Thomas Martinetz
The quasispecies theory is studied for dynamic replication landscapes. A meaningful asymptotic quasispecies is defined for periodic time dependencies. The quasispecies' composition…
How fast do structures emerge in hypercycle-systems?
S. Altmeyer, C. Wilke, T. Martinetz
A general framework for the simulation of reaction-diffusion systems with probabilistic cellular automata is presented. The basic reaction probabilities of the chemical model trans…
Large-scale evolution and extinction in a hierarchically structured environment
C. Wilke, S. Altmeyer, T. Martinetz
A class of models for large-scale evolution and mass extinctions is presented. These models incorporate environmental changes on all scales, from influences on a single species to…
