Shu-Xin Miao, The semi-convergence of GSI method for singular saddle point problems, Bulletin mathématique de la Société des Sciences Mathématiques de Roumanie, Nouvelle Série, Vol. 57 (105), No. 1 ...

For the saddle point formulation of the problem, using static condensation, we obtain a quadratic programming problem. We use Gauss-Seidel iterations to approximate the solution of this problem. The ...
