Abstract

We consider the extended linear complementarity problem (XLCP)introduced by Mangasarian and Pang [22], of whichthe horizontal and vertical linear complementarity problemsare two special cases.We give some new sufficient conditions for everystationary point of the natural bilinear programassociated with XLCP to be a solution of XLCP. We furtherpropose some unconstrained and bound constrained reformulationsfor XLCP, and study the properties of their stationary pointsunder assumptions similar to those for thebilinear program.
