摘要：
In this paper, we study a triple-parameter modified SSOR (TMSSOR) method for solving singular saddle point problems. We prove the semi-convergence of the TMSSOR method under suitable restrictions on the iteration parameters, and obtain the local optimal parameters which minimize the pseudo-spectral radii of the associated iteration matrices. Finally, numerical experiments demonstrate the effectiveness of the TMSSOR method for solving singular saddle point problems.
