Abstract

In this paper, we develop several related finite dimensional variational principles for discrete optimal transport (DOT), Minkowski type problems for convex polytopes and discrete Monge–Ampère equation (DMAE). A link between the discrete optimal transport, the discrete Monge–Ampère equation and the power diagram in computational geometry is established.
