An approach that separates geometric visibility preprocessing from a portfolio of incremental combinatorial searches is described, complemented by exact discrete one-swap descent, ruin-and-recreate, and elite crossover.
For $p \ge 1$, the $p$-Wasserstein distance measures the minimum cost of transporting probability mass between distributions, where moving unit mass between two points costs the $p$th power of their distance. For discrete distributions in one dimension, full transport is especially simple: after sorting, mass is matche...

The first sublinear approximation algorithm for the minimum dilation tree in the Euclidean plane is given, whose approximation ratio is $\tilde{O}(n^{14/15})$ and the algorithm runs in polynomial time.
