Abstract

We propose an interior point method to compute solution of linear complementarity problem LCP (qA) given that A is a real square hidden Z-matrix (generalization of Z-matrix) and q is a real vector. The class of hidden Z-matrix is important in the context of mathematical programming and game theory. We study the solution aspects of linear complementarity problem with \(A \in\) hidden Z-matrix. We observe that our proposed algorithm can process LCP (qA) in polynomial time under some assumptions. Two numerical examples are illustrated to support our result.
