Abstract: he subproblem generates trail step size dk always in trust region. dk is updated at every iter ation. Nonmonotone line search is used to solve subproblem when dk is not accepted. Global convergence is proved under some suitable conditions.
Key words: nonmonotone line search, quasiNewton method, trust region algorithm, global convergence
