In this paper, a new hybrid conjugate gradient method for solving unconstrained optimization problems is proposed. The proposed method inherits the features of the PRP, FR and NPRP conjugate gradient methods. The method satisfies the sufficient descent property independent of any line search and its global convergence is established under the strong Wolfe-Powell line search conditions. Numerical results show that the new algorithm is very competitive.
