Aitken's acceleration of the Restricted Additive Schwarz preconditioning using coarse approximations on the interface

Abstract

An enhancement of the restricted Additive Schwarz (RAS) preconditioning, based on the Aitken's acceleration of the convergence of the Schwarz method, is proposed. Its numerical performance is compared with the RAS preconditioning on the two dimensional Helmholtz problem.
