Abstract: A kind of decoding method and genetic operators are presented in this paper,which are used in combinatorial optimization.The method of genetic algorithm is employed to solve the optimization problem of ply stacking sequence of composite laminates with given plies,to satisfy the requirement of natural frequencies of vibration.The results of the example indicate that the method proposed in this paper converges to optimum solutions by searching only a small fraction of the slolution space.
