    • Multipreconditioned GMRES for Shifted Systems 

      Bakhos, T.; Kitanidis, P.K.; Ladenheim, S.; Saibaba, A.K.; Szyld, D. (2017-01-01)
      An implementation of GMRES with multiple preconditioners (MPGMRES) is proposed for solving shifted linear systems with shift-and-invert preconditioners. With this type of preconditioner, the Krylov subspace can be built ...
