摘    要:利用同伦方法求解无约束非凸优化问题,证明了在同伦映射为正则映射的条件下,选取合适的同伦方程,当算法可以排除鞍点时,同伦方法一定收敛到局部极小解,而非极大解.

关 键 词:无约束非凸优化  同伦方法  局部极小

Abstract:In this paper,a homotopy method is used to solve unconstrained nonconvex programming problems.It proves that,when the homotopy map is a regular map,after are saddle points eliminated in the homotopy algorithm,it must converge to a local minimum by choosing proper homotopy equation.
Keywords:unconstrained nonconvex programming  homotopy mehod  local minimum
