Effects of Chromosome Migration on a Parallel and Distributed Genetic Algorithm

In this paper we propose a parallel and distributed genetic algorithms (PDGA) on xed network topology multiprocessor systems in which each processor element carries out genetic operations on its own chromosome set and communicates with only the neighbors (we say chromosome migration). We execute the proposed method to investigate e ects of chromosome migration on the multiprocessor systems with ring, torus, and hypercube topology for benchmark problem instances. From the results, we nd that the ring topology is more suitable for our proposed parallel and distributed execution since it avoids immature convergence for its topological feature. We show its e ectiveness by experimental evaluation.
