Abstract

Conjugate gradient method is a method for solving unconstrained optimization problems,especially large-scale problems.In this paper a class of new conjugate gradient method contained the DY method is presented,and its global convergence is achieved under the Wolfe line search.Some numerical tests are carried out and the results show that the algorithm is effective.
