 abstract = {In a recent numerical study [Phys. Rev. E 64, 062501 (2001)] of a
discretized free-energy functional for the freezing of a hard-sphere
fluid, Valera, Pinski, and Johnson (VPJ) found unphysical, spurious
free-energy minima. They concluded that free-energy minima obtained in
similar previous work on hard spheres using relatively coarse
discretization scales were also numerical artifacts. We show here that
this conclusion is erroneous: the qualitatively unphysical results found
by VPJ do not originate from the coarseness of the mesh but, rather, are
themselves artifacts arising from the particular way in which VPJ
discretize the direct correlation function. When a more appropriate
discretization scheme is used, as in our own earlier work, the results
are physical.},
