Abstract

In this paper we propose an agent-based model of evolutionary algorithms (EAs) which extends seamlessly from concurrent single-host to distributed multi-host installations. Since the model is based on locally executable selection, we focus on the comparison of two selection mechanisms which accomplish with such a restriction: the classical tournament method and a new one called autonomous selection. Using the latter method the population size changes during runtime, hence it is not only interesting as a new selection mechanism, but also from the perspective of scalable networks.
