A modified prp conjugate gradient method is proposed in this paper based on the modified secant equation. the main properties of the new method are described as follows: (i) the parameter β k has not only gradient value information but also function value information; (ii) β k ≥ 0, ∀ k; (iii) the search direction generated by the presented method possesses both the sufficient descent and. This paper gives a modified prp method which possesses the global convergence of nonconvex function and the r linear convergence rate of uniformly convex function. furthermore, the presented method has sufficiently descent property and characteristic of automatically being in a trust region without carrying out any line search technique. numerical results indicate that the new method is.

In this paper, a modified conjugate gradient method is proposed for nonconvex optimization. this method possesses the sufficient descent property independent of any line search. the global convergence property of the algorithm is established under the wolfe line search strategy or the armijo line search condition, respectively. Test methods are responding to prp method with modified wwp line search, prp method with wwp line search and prp method with ywl line search [36], respectively.in the numerical results, the dimension of most of the problems becomes large, and the cpu time will increase in normal circumstances, but sometimes the computer system leads to the cpu time becoming smaller, such as the problems 4, 8. ‘nm’: the newton method ‘cgd’: the conjugate gradient method in ‘mnprp’: the modified nonlinear prp method ‘imnprp’: the improved modified nonlinear prp method. the results in tables 1 and 2 show that our methods performs very well both in the number of iterations and cpu time. the imnprp performs best among these methods.
