Detailed Description

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

Numerical policies for one finite-chain two-site DMRG update.

The local solve performs a fixed amount of work and installs the resulting smallest Ritz vector without requiring local convergence. The default truncation retains at least one singular state.

Template Parameters

Real	Real component type of the MPS scalar.
