A Polynomial Preconditioned Global CMRH Method for Linear Systems with Multiple Right-Hand Sides

open access: yesJournal of Applied Mathematics, 2013
The restarted global CMRH method (Gl-CMRH(m)) (Heyouni, 2001) is an attractive method for linear systems with multiple right-hand sides. However, Gl-CMRH(m) may converge slowly or even stagnate due to a limited Krylov subspace.

A Randomized Q-OR Krylov Subspace Method for Solving Nonsymmetric Linear Systems

open access: yesMathematics
The most popular iterative methods for solving nonsymmetric linear systems are Krylov methods. Recently, an optimal Quasi-ORthogonal (Q-OR) method was introduced, which yields the same residual norms as the Generalized Minimum Residual (GMRES) method ...
