abstract="{Summary: A generalized Moreau-Yosida based primal-dual active set
    algorithm for the solution of a representative class of bilaterally control
    constrained optimal control problems with boundary control is developed. The
    use of the generalized Moreau-Yosida approximation allows an efficient
    identification of the active and inactive sets at each iteration level. The
    method requires no step-size strategy and exhibits a finite termination
    property for the discretized problem class. In infinite as well as in finite
    dimensions a convergence analysis based on an augmented Lagrangian merit
    function is given. In a series of numerical tests the efficiency of the new
    algorithm is emphasized.}",
