The problem is approximated by a Moreau-Yosida type regularization. Optimality conditions for the regularized problem are derived and the convergence of the regularized problems is shown. In the last part of the paper, some numerical results are presented.application/pdfeng510Nonlinear optimal controlnonlocal radiation interface conditionsstate constraintsfirst-order necessary conditionssecond-order sufficient conditionsMoreau-Yosida approximationReport
