摘要
约束变尺度法是优化设计中最佳算法之一．本文根据该算法的基本理论和方法，编制了ＦＯＲＴＲＡＮ７７计算程序，并针对该算法在机械优化设计出现的问题作了改进，同时将中心差分算子技术引入优化过程，从而在很大程度上提高了解题效率、收敛精度和可靠性．
The constrained variable metric method(or WHP method) is one of the advanced nonlinear programing methods for optimization design, In this peper an effective FORTAN 77 computer program based on the basic theory of WHP method is presented. Improvements aiming at the imperfection of WHP method in applying to mecanical optimization design are achieved and the centre difference operator is introduced into WHP method and the competing effficency, the converging Precision and the reliability a-re r￣ to a considerable extent.
