Abstract: In this paper, we propose a
new estimation formula for optimum of
the Gauss-Seidel method with the preconditioner for solving a linear system arising from the usual
discretization of the 2-dimensional P.D.E. We show that this formula is better
estimation of the optimum .
Keywords and phrases: Gauss-Seidel method, SOR method, preconditioning.
