Abstract: HZ's conjugate gradient method (proposed by William W. Hager and Hongchao Zhang) has been proved to be an efficient method. In this paper, we prove the global convergence of HZ's method with Armijo-type line search. Our numerical experiments show that the new algorithm are more efficient and competitive with HZ's method with Wolfe line search in most cases.
