| Abstract: | In this paper several SIP algorithms are proposed and the choice of their optimal parametens are analyzed in the case where the coefficient matrix of the linear system is an L-matrix with nonvanishing diagonal elements. Numerical results are given to illustrate that the convergence of our algorithms with the optimal parameters is better than that of other algorithms and parameters. |
