Solving bound constrained optimization via a new nonmonotone spectral projected gradient method Original Research Article

In this paper, by introducing a new nonmonotone line search technique and combining it with the spectral projected gradient method, we propose a solution method for solving the bound constrained optimization problems. Under mild conditions, we obtain the global convergence even without requiring a prior of the existence of a limit point. Numerical tests are also given to show the efficiency of the proposed method.
