Comment on "Growth Inside a Corner: The Limiting Interface Shape"
  We examine the conjectured asymptotic shape of the three dimensional corner growth model [Olejarz et. al.,PRL, 108, 016102 (2012)] by mapping the model onto a restricted solid on solid model on a triangular lattice. By choosing appropriate boundary conditions, we are able to obtain high precision numerical results for the growth velocity using Monte Carlo simulations. We find that the numerical results are not consistent with the conjecture.
