An extension of the I + Smax preconditioner for the Gauss-Seidel method
A preconditioning technique based on the application of a fixed but arbitrary number of I + Smax steps is proposed. A reduction of the spectral radius of the Gauss-Seidel iteration matrix is theoretically analyzed for diagonally dominant Z-matrices. In particular, it is shown that after a finite...
