NP-completeness of the linear complementarity problem
We consider the linear complementarity problem (q,M) for which the data is the integer column vector \(q\in R^ n\) and the integer square matrix M of order n. GLCP is the decision problem: Does (q,M) have a solution? We show that GLCP is NP-complete in the strong sense.
