Abstract

In this paper, we investigate the iterative methods for solving the absolute value equations (AVEs). Using matrix splitting and the relaxed technique, a relaxed-based matrix splitting (RMS) method is presented. As special cases, we propose a relaxed-based Picard (RP) method, relaxed-based AOR (RAOR) method, and relaxed-based SOR (RSOR) method. These methods include some known methods as special cases, such as the Newton-based matrix splitting iterative method, the modified Newton type iteration method, the Picard method, a new SOR-like method, the fixed point iteration method, the SOR-like method, the AOR method, the modified SOR-like method, etc. Some convergence conditions of the proposed method are presented. Numerical examples verify the theoretical results and the advantages of the new methods.
