  • Abstract
    A trust-region algorithm based on new conic model is presented for unconstrained optimization problems by combining filter and nonmonotone technique. When a trial step is not successful, a filter line search is taken to reduce the number of re-solving subproblem as far as possible. The global convergence of the algorithm is proved under certain conditions. Numerical tests show the algorithm is effective.
