A New Sequential Optimality Condition for Constrained Nonsmooth Optimization

We introduce a sequential optimality condition for locally Lipschitz constrained nonsmooth optimization, verifiable just using derivative information, and which holds even in the absence of any constraint qualification. We present a practical algorithm that generates iterates either fulfilling the new necessary optimality condition or converging to stationary points of the infeasibility measure. A main feature of the devised algorithm is to...
