This question raised up after a talk given by Etienne Ghys about optimal transport at the student seminar of LLG. The talk is related to Cedric Villani work about optimal transport but was focused on the very beginning of the theory, i.e. on the very rich and stimulating memoir of Gaspard Monge : Memoire sur la theorie des deblais et remblais.

The proposed challenging problem is just an adaptation of an idea Monge has developped in his memoir.
