| Abstract: | In this paper,a new class of memory gradient methods for unconstrained optimization problem is presented.The convergence of the algorithms with strong Wolfe line search is proved.The linear convergence rate is investigated when the objective function is uniformly convex.Numberical experiments show that the new algorithm is very effcient. |
