| Abstract: | 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. |
