【Abstract】 A new nonlinear optimization method called variable metric gradient projection method is presented. It is a combination of mathematical programming with optima lity criterion. In each iterative process the metric of the design space is changed continuously. A general computer program is developed. The results of numerical examples show that the accuracy and convergence are satisfactory and it will be useful for practical purposes.更多还原
