Abstract. In this paper, an efficient new nonlinear conjugate gradient method is proposed for the unconstrained optimization problems, which possesses the following property: the sufficient descent condition holds without any line search. Under the strong Wolf Non-monotone line search, we proved the global convergence of the FR method for strongly convex functions.
The numerical experiments show that the FR method is especially efficient.
