Abstract:

The symmetric SOR method SSOR-method for solving the linear system Au b is considered. The basic properties of the SSOR method are summarized, and a procedure is given for estimating the optimum relaxation factor omega and the corresponding spectral radius of the SSOR matrix S sub omega. Two procedures for accelerating the convergence of the SSOR method are considered, one based on conjugate gradient acceleration and the second based on the use of Chebyshev acceleration. Two versions of conjugate gradient acceleration are considered--the nonadaptive and the adaptive. Author
