Abstract
This paper deals with the analysis of restarted GMRES, GMRES(m) [2], preconditioned by multigrid. Based on Fourier analysis [1,3] a relation to other techniques in which multi-stage parameters for smoothing methods are optimized can be established. Line smoothers with the additional Krylov acceleration are used to avoid plane smoothers in multigrid for several 3D anisotropic problems.
