Solving Linear Inequalities In A Least Squares Sense
, 1994 . In 1980, Han [6] described a finitely terminating algorithm for solving a system Ax b of linear inequalities in a least squares sense. The algorithm uses a singular value decomposition of a submatrix of A on each iteration, making it impractical for ...

GMRES on (Nearly) Singular Systems
, 1994 . We consider the behavior of the gmres method for solving a linear system Ax = b when A is singular or nearly so, i.e., ill-conditioned. The (near) singularity of A may or may not affect the performance of gmres, depending on the nature of the system ...

A preconditioned Krylov subspace method for the solution of least squares problems
, 1994 We present an iterative method of preconditioned Krylov type for the solution of large least squares problems. We prove that the method is robust and investigate its rate of convergence.

Optimal Injection Operator and High Order Schemes for Multigrid Solution of 3D Poisson Equation
, 1999 We present a multigrid solution of the three dimensional Poisson equation with a fourth order 19-point compact finite difference scheme. Using a red-black ordering of the grid points and some geometric considerations, we derive an optimal scaled ...

Improvement of Incomplete Factorizations by a Sparse Secant Method.
, 1990 In the present paper, the improvement of an incomplete factorization of a non-symmetric matrix A is discussed. Starting from the ideas of sparsity preserving quasi-Newton methods, an algorithm is developed which improves the approximation of A by the ...

Adaptively Preconditioned Gmres Algorithms
. The restarted GMRES algorithm proposed by Saad and Schultz [22] is one of the most popular iterative methods for the solution of large linear systems of equations Ax = b with a nonsymmetric and sparse matrix.
