Currently, Zhang [17] takes some modification of the Wei-Yao-Liu nonlinear conjugate gradient method suggested by Wei et al. [18] such that the modified method called NPRP method. Dai and Wen [19] make a simple modification to the NPRP called DPRP method. In this paper, we change denominator of DPRP method such that the modified DPRP method possesses global convergence under exact line search. Numerical results show that the proposed method is efficient for the given test functions when compared with classical formula and DPRP method.
