一类修正的DY共轭梯度法
A Class of Modified DY Conjugate Gradient Method
摘要
Abstract
A class of modified DY Conjugate gradient methods are proposed based on DY conjugate gradient methods proposed by Dai and Yuan in 1999.The search direction of the methods are proved to possess descent property when step length satisfies the Wolfe line search conditions,and the methods are global convergence to the general function.关键词
