چكيده فارسي :
We study the performance of the backward generalized Gauss-Seidel (BGGS) iterative scheme to solve stabilized saddle point problems. Moreover, we construct a block triangular preconditioner from BGGS splitting to improve the rate of convergence of Krylov subspace methods. We report numerical experiments to illustrate the efficiency of the proposed preconditioner
