Abstract:This paper gives a decompose of projected quasi Newton algorithm in association with nonmonotone trust region for solving nonlinear equality constrained optimization problems. The proposed method is globally convergent even if conditions are mild. In order to assure local superlinear rate and obtain other convergence properties, a second order correction step which brings the iterates closer to the feasible set is described. The correction step allows to prove that the proposed algorithm is also locally superlinear convergent.
Keywords:Trust region  nonmonotone technique  constrained optimization
