Optimal transport geodesic
WebThe optimal transport (OT) problem is often described as that of finding the most efficient way of moving a pile of dirt from one configuration to another. Once stated formally, OT … Web0 <1. A geodesic, also called an optimal transport path, in this space is a weighted directed graph whose edges are geodesic segments. Moreover, when Xis a geodesic metric space of curvature bounded above, we nd in x2, a universal lower bound depending only on the parameter for each comparison angle between edges of any optimal transport path.
