Detailed Description

template<class MATRIX, typename inverse_type = typename MATRIX::value_type>
class RelaxationBlockSSOR< MATRIX, inverse_type >

Symmetric block Gauss-Seidel method with possibly overlapping blocks.

This class implements the step() and Tstep() functions expected by SolverRelaxation and MGSmootherRelaxation. They perform a multiplicative Schwarz method on the blocks provided in the BlockList of AdditionalData in symmetric fashion. Differing from PreconditionBlockSSOR, these blocks may be of varying size, non-contiguous, and overlapping. On the other hand, this class does not implement the preconditioner interface expected by Solver objects.
