机械系统动态优化设计的混合遗传基因方法

A Mixed Genetic Algorithm for Dynamic Optimization Design of a Mechanical System

融合复合形法和基因算法提出一种可以有效地解决机械系统动态优化设计问题的随机优化算法——混合遗传基因法．该法以遗传基因方法实现代间进化，以复合形法改进代间较差个体以加速进化．数值分析结果表明，该方法结果正确。

A new stochastic algorithm, the mixed genetic algorithm for solving the dynamic optimization problem of a mechanical system is developed by combining the compound shape method with the genetic algorithm. The genetic algorithm is used to realize the evolution between generations in the selection stage and the compound shape method is used to improve the worse individuals in order to accelerate evolution. The results of a numerical analysis show that it is a simple but effective and reliable method.
