WebFeb 26, 2024 · We can easily see that the optimal transport corresponds to assigning each point in the support of $p(x)$ to the point right above in the support of $q(x)$. For all points, the distance is 1, and since the distributions are uniform, the mass moved per point is 1/5. Therefore, the Wasserstein distance is $5\times\tfrac{1}{5} = 1$.
