Abstract

Recently, the P"0 function nonlinear complementarity problem (NCP) has attracted a lot of attention among researchers. Various assumed conditions, which ensure that the NCP has a solution have been proposed. In this paper, by using the notion of an exceptional family of elements we develop a sufficient condition which ensures that the solution set of the P"0 function NCP is nonempty and bounded. In particular, we prove that many existing assumed conditions imply this sufficient condition. Thus, these conditions imply that the solution set of the P"0 function NCP is nonempty and bounded. In addition, we also prove directly that a few existence conditions imply that the solution set of the P"0 function NCP is bounded.
