Optimal shape of an open mining pit

Abstract:

Given a vein of ore in the ground, which is to be extracted by open-pit mining, what is the shape which will maximize profit? This problem is often treated by discretization, but we present a new way to handle directly the continuous case. We set it up as an optimal transportation problem, which we solve using Kantorovitch duality. This is joint work with Maurice Queyranne
