| Abstract: | The Generalized Successive Over-Relaxation(i.e.GSOR) is discussed.Two methods to determine the optimal relaxation factor for GSOR are presented.Furthermore,the feasibility and validity of two methods was verified through experiment instances and made it possible to execute SOR algorithm more efficiently. |
