%A Y.M. Ermoliev %A V.I. Norkin %T Constrained Optimization of Discontinuous Systems %X In this paper we extend the results of Ermoliev, Norkin and Wets [8] and Ermoliev and Norkin [7] to the case of constrained discontinuous optimization problems. In contrast to [7] the attention is concentrated on the proof of general optimality conditions for problems with nonconvex feasible sets. Easily implementable random search technique is proposed. %C IIASA, Laxenburg, Austria %D 1996 %I WP-96-078 %L iiasa4949
