Abstract

In this paper, we propose a modified SQP method, which uses neither a penalty function nor a filter, for the nonlinear programming problems. The proposed mechanism for accepting the trial step is carried out by a nonmonotone technique. Under some conditions, we establish the global convergence of the algorithm. Some numerical results are presented to show the effectiveness of the proposed algorithm.
