Abstract
In this paper, we propose two different modified Uzawa methods for solving the saddle point problems, and prove the convergence of the proposed methods. We solve a lower-upper triangular system per iteration in the proposed methods, instead of only solving a lower one. Numerical experiments show that our proposed methods with four parameters perform much faster than previous Uzawa methods with three parameters.
