WebWe briefly use “optimal transport theory” as a starting point, and a way as well, to derive two canonical couplings: “statistical independence” and “logical indetermination”. A symmetric list of properties is provided and notably the so called “Monge’s properties”, applied to contingency matrices, and justifying the ⊗ versus ⊕ notation. Web5 feb. 2024 · Although originally developed in a seemingly niche context, Monge’s “sandcastle” problem arises in a wide array of fields. For instance, it can be applied in economics, where its solutions are used to minimise the cost of transporting goods, but also in computing, where it forms the basis of the field of linear programming.
