应用同伦方法的下楼法

A Downstairs Method with Homotopy

针对下楼法中求非线性方程组初值点不易取的问题，采用连续同伦方法来解决这一问题．并对原算法进行了改进，使得算法能自动地很快找到全局极小．通过对几个典型函数测验，证明了其有效性．

For the problem that the initial value of nonlinear equation of the paper is difficult to choose, we present a solution by using continuation homotopy methodWith the improvenat of the original alogrithm,the alogrithm can quickly reach the global minimizerBy testing some typical function,its efficiency is proved
