摘要
在这篇论文，关于β _k^(PRP ) 的β _ k 的一个新区域被给。Withtwo Armijo 类型线搜索，作者调查依赖 PRP 的全球集中性质结合坡度方法，它扩大坡度方法由 Grippo 和 Lucidi 和奶妈和元(1997 )(2002 ) 证明了的 PRPconjugate 的全球集中结果。
In this paper, a new region of βk with respect to ;βk^PRP is given. With two Armijo-type line searches, the authors investigate the global convergence properties of the dependent PRP conjugate gradient methods, which extend the global convergence results of PRP conjugate gradient method proved by Grippo and Lucidi （1997） and Dai and Yuan （2002）.
