摘要: 本文以梯度法为基拙,提出了一种新的命名为无约束梯度最优方向法的寻优方法(简称UGODA法)。它的基本思想是:寻求每次迭代的最优方向,从而获得目标函数的最优值。通过计茸机验证,其效果是较令人满意的。

关键词: 最优方向 梯度 迭代 最优解

Abstract: On the basis of the gradient algorithm.a new optimization method named unconstrained gradient optimum direction algorithm(UGODA)is presented in this paper. Its basic idea is to find the optimum direction of each iterat-
ion so as to obtain the optimum solution.The result examined by a computer
is satisfactory.
