KW - Convergence, SSOR-like method, convergence factor.
AB - <p style="text-align: justify;">In this paper, we propose a new SSOR-like method with four parameters to
solve the augmented system. And we analyze the convergence of the method and get
the optimal convergence factor under suitable conditions. It is proved that the optimal
convergence factor is the same as the GMPSD method [M.A. Louka and N.M. Missirlis,

displacement methods for augmented systems, Numer. Math. 131(2015)
