Abstract

In this paper, we show that the deflation method can be viewed as a possible implementation of the CG method with multilevel preconditioner. Further, we demonstrate efficiency and robustness of different implementations of multilevel preconditioners with different "coarse grid" spaces by solving a simple model problem.
