A block GMRES method with deflated restarting for solving linear systems with multiple shifts and multiple right-hand sides
The restarted block generalized minimum residual method (BGMRES) with deflated restarting (BGMRES-DR) was proposed by Morgan to dump the negative effect of small eigenvalues from the convergence of the BGMRES method. More ...
Restarted Hessenberg method for solving shifted nonsymmetric linear systems
It is known that the restarted full orthogonalization method (FOM) outperforms the restarted generalized minimum residual (GMRES) method in several circumstances for solving shifted linear systems when the shifts are handled ...
