摘要
Abstract
Conjugate gradient methods are a class of important methods for solving large-scale uncon-strained optimization problems.In this paper,we present a modified conjugate gradient method based on the conjugate gradient parameter of Liu et al..The new method has sufficient descent property independent of any line search. We establish the convergence results of the algorithms under the Armijio line search conditions.关键词
