Abstract

In a network topology design apparatus for designing a network topology connecting a plurality of points by communication lines so that a predetermined traffic volume is transmitted between the plurality of points, chromosomes wherein the network topology is represented in a matrix are created, and a genetic algorithm is applied to evolve the chromosomes in order to improve cost performance. Then by applying a local search method to the chromosomes which have been evolved by the genetic algorithm, to search the chromosomes in the neighborhood of the evolved chromosomes, a chromosome with a better cost performance is determined. In this way, genetic algorithms and local search methods are applied to design a network topology with excellent cost performance.
