sweep_single()

bool syten::MPS::TDVP::LBOWorker::sweep_single	(	Timer &	timer,
		SRDef &	trunc_error,
		SRDef &	krylov_error
	)

Does a single sweep of single-site TDVP, delivering the timer and errors in its arguments and returning true if we should exit due to having received a signal.

Remarks

If my understanding is correct, this procedure should give a second-order integrator, as the solution of equations on the left-to-right sweep is the direct inverse of the equations on the right-to-left sweep.
