syten::Krylov::Evolution::ExtrapolatingHeuristic< Solver > Class Template Reference

The ExtrapolatingHeuristic class tries to extrapolate the number of timesteps that can be taken with one more Krylov vector and the runtime for adding this vector, and compares both to building a new Krylov space from scratch. More...

Detailed Description

template<typename Solver>
class syten::Krylov::Evolution::ExtrapolatingHeuristic< Solver >

The ExtrapolatingHeuristic class tries to extrapolate the number of timesteps that can be taken with one more Krylov vector and the runtime for adding this vector, and compares both to building a new Krylov space from scratch.
