摘要
本文提出一种新的约束非线性离散优化方法——可行下降系数法(FDCM)该算法计算原理简单,程序易编.通过许多工程实际问题的计算表明,该算法和现有离散优化方法相比,有较高的可靠性与有效性,便于工程技术人员掌握和使用.
A method without using artificial variables, to solve the feasiable points for linear constraint in optimal design is introduced.The method given by R.Fletcher is expanded.The calculating practice shows that the less calculation work is needed and faster convergence rate can be reached.
