摘要
在本文中,我们给出一个求解无约束优化问题的秩一适定方法,该方法具有下述较好性质:校正矩阵是对称正定的;在适当条件下,对非凸函数拥有全局收敛性.我们还给出数值检验结果.
We propose a rank-one fitting method for solving unconstrained optimzation problems. This method possesses some better properties.. (a) which can ensure that the undated matrices is symmetric and positive definite; (b) the global convergence for non-convex function is established under suitable conditions. The numerical results are reported.
