Online Correlation Clustering with Metric Weights

Sami Davies, Benjamin Moseley, Heather Newman

The standard online version of correlation clustering is prohibitively hard, as even randomized algorithms cannot achieve competitive ratio better than . Prior works bypass t…

Online Correlation Clustering: Simultaneously Optimizing All -norms

Sami Davies, Benjamin Moseley, Heather Newman

The -norm objectives for correlation clustering present a fundamental trade-off between minimizing total disagreements (the -norm) and ensuring fairness to individu…

Robust Gittins for Stochastic Scheduling

Benjamin Moseley, Heather Newman, Kirk Pruhs +1

A common theme in stochastic optimization problems is that, theoretically, stochastic algorithms need to "know" relatively rich information about the underlying distributions. This…

Simultaneously Approximating All -norms in Correlation Clustering

Sami Davies, Benjamin Moseley, Heather Newman

This paper considers correlation clustering on unweighted complete graphs. We give a combinatorial algorithm that returns a single clustering solution that is simultaneously …

Online -Median with Consistent Clusters

Benjamin Moseley, Heather Newman, Kirk Pruhs

We consider the online -median clustering problem in which points arrive online and must be irrevocably assigned to a cluster on arrival. As there are lower bound instances…

Fast Combinatorial Algorithms for Min Max Correlation Clustering

Sami Davies, Benjamin Moseley, Heather Newman

We introduce fast algorithms for correlation clustering with respect to the Min Max objective that provide constant factor approximations on complete graphs. Our algorithms are the…

Matroid-Based TSP Rounding for Half-Integral Solutions

Anupam Gupta, Euiwoong Lee, Jason Li +3

We show how to round any half-integral solution to the subtour-elimination relaxation for the TSP, while losing a less-than-1.5 factor. Such a rounding algorithm was recently given…

Uniform Edge Betweenness Centrality

Heather A. Newman, Hector Miranda, Rigoberto Florez +1

The edge betweenness centrality of an edge is loosely defined as the fraction of shortest paths between all pairs of vertices passing through that edge. In this paper, we investiga…

Edge-Transitive Graphs

Heather A. Newman, Hector Miranda, Darren A. Narayan

A graph is said to be edge-transitive if its automorphism group acts transitively on its edges. It is known that edge-transitive graphs are either vertex-transitive or bipartite. I…
