WebJul 21, 2011 · 4. Finding routes for a car is pretty easy: you store a weighted graph of all the roads and you could use Djikstra's algorithm. A bus route is less obvious. It may be less obvious, but the reality is that it's merely another dimension to the car problem, with the addition of infinite cost calculation. WebOptimal Transport (Peyré et al., 2024) is a mathematical framework that defines distances or similari-ties between objects such as probability distributions, either discrete or continuous, as the cost of an optimal transport plan from one to the other. Figure 2: We illustrate, for a given 2D point cloud, the optimal transport plan obtained from
