orthogonalization_strategy

template<typename VectorType = Vector<double>>

LinearAlgebra::OrthogonalizationStrategy SolverMPGMRES< VectorType >::AdditionalData::orthogonalization_strategy

Strategy to orthogonalize vectors.

use_truncated_mpgmres_strategy

template<typename VectorType = Vector<double>>

bool SolverMPGMRES< VectorType >::AdditionalData::use_truncated_mpgmres_strategy

If set to true (the default) a "truncated" search space is constructed consisting of the span of independent Krylov space associated with each preconditioner. If set to false, the full MPGMRES strategy for constructing the search space is used. This space consists of all possible combinations of iterative preconditioner applications; see the documentation of SolverMPGMRES for details.
