A Better-than-2 Approximation for k-Median Part I: The Power of General Bids

Rares-Darius Buhai, Vincent Cohen-Addad, Henry Fleischmann +6

The Greedy algorithm of Jain, Mahdian, Markakis, Saberi, and Vazirani was the best Lagrangian-multiplier-preserving (LMP) approximation algorithm for facility location, and thus th…

A Better-than- Approximation for -Median Part II: Stable Instances

Rares-Darius Buhai, Vincent Cohen-Addad, Henry Fleischmann +6

We consider the -median problem on general metric spaces, subject to the condition that the instances are -stable (i.e., the optimal solution using centers has a cost a…

Second Price Matching with Complete Allocation and Degree Constraints

Rom Pinchasi, Neta Singer, Lukas Vogl +1

We study the Second Price Matching problem, introduced by Azar, Birnbaum, Karlin, and Nguyen in 2009. In this problem, a bipartite graph (bidders and goods) is given, and the profi…

Static to Dynamic Correlation Clustering

Nairen Cao, Vincent Cohen-Addad, Euiwoong Lee +7

Correlation clustering is a well-studied problem, first proposed by Bansal, Blum, and Chawla [Mach. Learn. '04]. The input is an unweighted, undirected graph. The problem is to clu…

Solving the Correlation Cluster LP in Sublinear Time

Nairen Cao, Vincent Cohen-Addad, Shi Li +7

Correlation Clustering is a fundamental and widely-studied problem in unsupervised learning and data mining. The input is a graph and the goal is to construct a clustering minimizi…

Understanding the Cluster LP for Correlation Clustering

Nairen Cao, Vincent Cohen-Addad, Euiwoong Lee +3

In the classic Correlation Clustering problem introduced by Bansal, Blum, and Chawla (FOCS 2002), the input is a complete graph where edges are labeled either or , and the g…
