  Although Potent purports to use only radial velocities in retrieving the
potential velocity field of galaxies, the derivation of transverse components
is implicit in the smoothing procedures. Thus the possibility of using
nonradial line integrals to derive the velocity field arises. In the case of
inhomogeneous distributions of galaxies, the optimal path for integration need
not be radial, and can be obtained by using max-flow algorithms. In this paper
we present the results of using Dijkstra's algorithm to obtain this optimal
path and velocity field.
