Generalized SOR-Like Iteration Method for Linear Complementarity Problem

Abstract EN

In this paper, we present a generalized SOR-like iteration method to solve the non-Hermitian positive definite linear complementarity problem (LCP), which is obtained by reformulating equivalently the implicit fixed-point equation of the LCP as a two-by-two block nonlinear equation.

The convergence properties of the generalized SOR-like iteration method are discussed under certain conditions.

Numerical experiments show that the generalized SOR-like method is efficient, compared with the SOR-like method and the modulus-based SOR method.
