减少优化设计中直接法计算量的探讨

A Discussion About Reducing Amount of Calculation of Direct Method

直接算法的计算量大 ,而且没有严格的理论依据 .文中提出的广义插值法 ,为减少直接优化探索法的计算量提供了有效途径 .实例计算证明该法不仅可靠 ,而且可节省将近 36 %的计算量 .在充分计算实践的基础上 ,对减少直接法的计算量理论与方法作了探讨 。

The general interpolation mentioned in this article provides an effective way for reducing the amount of calculation of direct optimal exploration. It has been testified by real case calculations that the interpolation not only is reliable but also can save the amount of calculation by nearly 36%. The disadvantages of direct method that has large amount of calculation and lacking strict theoretical basis still exist. If it can not be overcome, they will not only seriously affect the application of this method, but also hinder its further research. Based on sufficient calculation practice, this article has made a primary discussion about the theory and a method of reducing the amount of calculation, and has achieved some satisfactory results.
