                   nonlinear equality constrained optimization problems. The
                   code is designed for the efficient solution of large
                   problems and provides the user with a variety of linear
                   algebra techniques for solving the subproblems occurring in

                   but when it is not available, limited memory quasi-Newton
                   approximations are made. The performance of the code is
                   studied using a set of difficult test problems from the
