A class of conjugate gradient methods for unconstrained optimization

LI An-kun

Abstract

Conjugate gradient method is a method for solving nonlinear optimization problems,especially large-scale problems.A new nonlinear conjugate gradient formula is presented in this paper.This method with the proposed formula and an inexact line search of Wolfe conditions are used is global convergence.Some numerical tests have been made and the results show that the algorithm is effective.
