Optimum Selection of Composite Material by Genetic Algorithm.

In this paper, Genetic Algorithm is applied to the discrete optimization of a structure composed of composite material. The finite-element method is used for analysis of the structure. To improve the reliability and the efficiency of the simple GA, automatic linking of design variables, mutation with high probability, and reduction of the population size are proposed. The numerical example presented here will show that the efficiency of GA can be improved without sacrificing the reliability of GA by introducing these procedures.
