Abstract: A new artificial intelligent optimal method complex genetic algorithm, which is fit for solving the mechanical dynamic optimization design problem, is established by the way of combining complex shape method and genetic algorithm. Based on genetic algorithm evolution between generations, after selection, improvement operation is used to improve the worst individuals in order to accelerate evolution. Also, theoretical analysis for the more effective optimum seeking mechanism of the algorithm is finished. The example calculation proved that it is a successful and simple method.
