一种新的Armijo型线搜索条件

A Kind of New Armijo Type Line Search Conditions

本文在几种常见的Armijo型线搜索基础上,提出了一种新的Armijo型线搜索条件,并证明了由Du等人提出的杂交共轭梯度法的全局收敛性。数值实验表明新方法对于给定的测试函数是有效的。

In this paper,a kind of new Armijo type line search conditions is presented on the basis of several common types of Armijo line search,which guarantees the global convergence of the hybrid conjugate gradient method proposed by Du etc.Numerical experiments show that the new method is effective for the given test functions.
