The Exact Bipartite Matching Polytope Has Exponential Extension Complexity
Xinrui Jia, Ola Svensson, Weiqiang Yuan
Given a graph with edges colored red or blue and an integer , the exact perfect matching problem asks if there exists a perfect matching with exactly red edges. There exists…
Towards Non-Uniform k-Center with Constant Types of Radii
Xinrui Jia, Lars Rohwedder, Kshiteej Sheth +1
In the Non-Uniform k-Center problem we need to cover a finite metric space using k balls of different radii that can be scaled uniformly. The goal is to minimize the scaling factor…
Nearly-Tight and Oblivious Algorithms for Explainable Clustering
Buddhima Gamlath, Xinrui Jia, Adam Polak +1
We study the problem of explainable clustering in the setting first formalized by Dasgupta, Frost, Moshkovitz, and Rashtchian (ICML 2020). A -clustering is said to be explainabl…
Fair Colorful k-Center Clustering
Xinrui Jia, Kshiteej Sheth, Ola Svensson
An instance of colorful k-center consists of points in a metric space that are colored red or blue, along with an integer k and a coverage requirement for each color. The goal is t…
