A line search filter two piece update of reduced Hessian method for nonlinear equality constrained optimization: global convergence

A line search filter two piece update of reduced Hessian method is proposed for nonlinear constrained programming by using Fletcher and Leyffer's filter method, which replaces the traditional merit function. We develop a two - piece updated projected Hessian algorithm with line search filter to solve nonlinear equality constrained optimization. Under mild assumptions it is shown that every limit point of the sequence of iterates generated by the algorithm is feasible, and that there exists at least one limit point that is a stationary point for the problem under consideration. The numerical experiments indicate that the algorithm is eft. ective.
