Detailed Description

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

Policies for an alternating finite-chain two-site DMRG run.

One sweep is one complete directional traversal. A zero energy tolerance selects 100 * numeric_limits<Real>::epsilon().

Template Parameters

Real	Real component type of the MPS scalar.
