Query: Half-quadratic transportation problems   We present a primal--dual memory efficient algorithm for solving a relaxed
version of the general transportation problem. Our approach approximates the
original cost function with a differentiable one that is solved as a sequence
of weighted quadratic transportation problems. The new formulation allows us to
solve differentiable, non-- convex transportation problems.
