Aprication of genetic algorithm-based relay search method to multi-optimization problem

Genetic algorithms (GAs) based on multi-point search method and crossover operation are one of the useful search procedures for combinatrial optimization problems and also applied to many kinds of practical optimization. However, in general , the GAs have a tendency to go down rapidly of the diversity of the population in the process of searching. In this study, in order to consider the application to optimal design problems in structures, Genetic Algorithm with Relay Search Method, RS-GA, is developed in this study. Some results of numerical examples are presented so as to demonstrate the suitability of this RS-GA.
