摘要
本文对机械设计中离散变量优化问题进行了讨论,提出了一个用于全离散变量或混合离散变量优化设计的方法——模式与随机搜索法。文中阐述了算法的原理,给出了迭代公式与框图。考核结果表明,本算法比通常的优化方法具有更好的可靠性与有效性,所得到的离散最优解更合理,并且计算时间与迭代次数明显减少。
In this paper,the problem of mixed discrete contmuous variable optimization in mechan- ical design was discussed.A new method,the pattern-random search method,applied to optimum design of all discrete or mixed discrete continuous variables was put forward.The principle of algorithm was discussed and the iterative formulas and the flow chart were given in this article.The results of examination showed that the algorithm was more reliable and ef- fective than general optimization methods.This method applied to design,the optimal results will be ore reasonable and the time for computing and the frequency of iteration can be obvi- ously reduced.
