Wolfe 线搜索下一种修正的 HS 共轭梯度法及其全局收敛性
Global convergence of a modified HS conjugate gradient method under wolfe-type line search
摘要
Abstract
A modified HS conjugate gradient method(WHS) was proposed .The method could generate sufficient descent direction for the objective function ,at the same time the property was independent of the line search method used .Global convergence of new methods under Wolfe line search was proved .Numerical experiment results showed that the algorithm was effective .关键词
