| 摘 要： | 本文描述了一种逐步缩小搜索域的全局优化法,利用此方法在全域随机投点进行判断,可以确定全局最小点所在的邻域,并给出该域中近似最小点值及其函数估值。在此邻域中再用局部优化梯度法,即可得到全局最小点。此法收敛迅速。使用方便,已用于微波电路最优化通用设计程序。最后给出验算结果和应用实例。

| Abstract: | The paper describes a global optimization method based on random search algorithm. This method can determine the neighborhood of the global optimum solution and the estimate of variables, as well as objective function values in this neighborhood. The estimated variables can be used as initial starting point for local gradient optimizatiom approach. Then the global optimum will be obtained. This method have been successfully used in microwave circuits design, Several examples are given in the paper. |
