Optimization with marginals and moments pdf
WebMoment Constrained Optimal Transport problem (MCOT) is achieved by a nite discrete measure. Interestingly, for multimarginal OT problems, the number of points weighted by this measure scales linearly with the number of marginal laws, which is encouraging to bypass the curse of dimension.

WebMay 9, 2024 · Download PDF Abstract: In distributionally robust optimization the probability distribution of the uncertain problem parameters is itself uncertain, and a fictitious adversary, e.g., nature, chooses the worst distribution from within a known ambiguity set. A common shortcoming of most existing distributionally robust optimization models is that … Webmargins and the multivariate dependence structure can be separated. The dependence structure can be represented by an adequate copula function. Moreover, the following corollary is attained from eq. 1. Corollary 2.2. Let F be an n-dimensional C.D.F. with continuous margins F 1,...,F n and copula C (satisfying eq. 1). Then, for any u = (u 1 ...
