Detailed Description

template<typename Solver>
struct syten::Krylov::Evolution::Evolver< Solver >

Base class from which different heuristics inherit.

Different heuristics then primarily override do_recycle() and, if necessary, evolve() and continue_evolution() to include additional steps.

The documentation for this struct was generated from the following file:
