Detailed Description

template<uni20::Real Real>
struct uni20::tensor_network::DmrgLanczosOptions< Real >

Numerical policy for one lightweight DMRG local Lanczos solve.

The solve performs at most the requested number of effective-Hamiltonian applications and returns the smallest Ritz vector without applying a convergence criterion or restarting the Krylov basis.

Template Parameters

Real	Real component type of the local wavefunction scalar.
