Web-much - broader overview on optimal transport). In Chapter 1 we introduce the optimal transport problem and its formulations in terms of transport maps and transport plans. Then we introduce basic tools of the theory, namely the duality formula, the c-monotonicity and discuss the problem of existence of optimal maps in the model case cost ... 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.
