A New Spectral Conjugate Gradient Method for Unconstrained Optimization and Its Convergence

Published: Jan 1, 2013
Abstract
Strong Wolfe line search conditions cannot guarantee the global convergence of standard CD conjugate gradient method.A new spectral conjugate gradient method for unconstrained optimization was proposed.This method is the same as the standard CD method when the line search is exact.Moreover,the corresponding algorithm was proved to be descent and globally convergent if the Wolfe line search is used.Preliminary numerical results show that the new...
