A Robustified Greedy Algorithm for Online Transportation with Improved Competitive Guarantees

Ritesh Seth, Syamantak Das, Sharath Raghvendra

We study the \emph{online transportation problem}, in which requests arriving sequentially in a metric space must be irrevocably assigned to capacitated facilities. Beyond…

Computing All Optimal Partial -Wasserstein Matchings on the Line

Sebastian Angrick, Jacobus Conradi, Mónika Csikós +5

For , the -Wasserstein distance measures the minimum cost of transporting probability mass between distributions, where moving unit mass between two points costs the $p…

Geometric Bipartite Matching Based Exact Algorithms for Server Problems

Sharath Raghvendra, Pouyan Shirzadian, Rachita Sowle

For any given metric space, obtaining an offline optimal solution to the classical -server problem can be reduced to solving a minimum-cost partial bipartite matching between tw…

A New Robust Partial -Wasserstein-Based Metric for Comparing Distributions

Sharath Raghvendra, Pouyan Shirzadian, Kaiyi Zhang

The -Wasserstein distance is sensitive to minor geometric differences between distributions, making it a very powerful dissimilarity metric. However, due to this sensitivity, a…
