Multi-marginal problems

[Carlier, Oberman (Univ. Mc Gill), Oudet (Univ. of Grenoble) - New numerical methods for the Wasserstein barycenter and related multi-marginals problems were investigated [49] . A first method uses linear programming, in an implementation that was more efficient than expected. A second method takes advantage of the quadratic structure and leads to an efficient algorithm that can be used in texture synthesis problems arising in image processing.
