WebThe Monge formulation of optimal transport restricts itself to transportation between two uniform discrete densities whose support has the same size n n. In particular, it seeks a mapping from one density α α to another β β, where. α = n ∑ i=1aiδxi, β = n ∑ j=1bjδyj α = ∑ i = 1 n a i δ x i, β = ∑ j = 1 n b j δ y j. Web2.3.
