In our recent works we computed with very high accuracy (at least 10e-26) Stokes' waves of different amplitude and provided a new, more accurate, estimation for the maximum amplitude of the Stokes' wave. We were able to compute Stokes' waves with amplitudes which differs from the maximum one less than by 0.003%.
