  We demonstrate a computational scheme which drastically decreases the
required time to get theoretical predictions based on chiral two- and
three-nucleon forces for observables in three-nucleon continuum. For a
three-nucleon force containing N short-range terms all workload is reduced to
solving N+1 Faddeev-type integral equations. That done, computation of
observables for any combination of strengths of the contact terms is done in a
flash. We demonstrate on example of the elastic nucleon-deuteron scattering
observables the high precision of the proposed emulator and its capability to
reproduce exact results.
