具有充分下降性的修正 HS共轭梯度法
A Modified HS Conjugate Gradient Method With Sufficient Descent Properties
摘要
Abstract
This paper adopts the search direction given Cheng Wanyou and proposes a modified HS con -jugate gradient method .The presented method can make the search direction with sufficient descent con -dition without any line search .Under suitable conditions , we prove that the method is globally convergent .关键词
