Online Submodular Welfare Maximization: Computation is not the Bottleneck

Rajan Udwani, David Wajc

We revisit the online submodular welfare maximization problem (OSW), a vast generalization of numerous well-studied online allocation problems, including online bipartite matching,…

Asymptotically Tight Fractional Online Matching Under Edge Arrivals

David Wajc

In this brief note, we close the asymptotic gap between known upper and lower bounds for fractional online matching under edge arrivals. We prove that the optimal competitive ratio…

Chasing Submodular Objectives, and Submodular Maximization via Cutting Planes

Niv Buchbinder, Joseph, Naor +1

We introduce the \emph{submodular objectives chasing problem}, which generalizes many natural and previously-studied problems: a sequence of constrained submodular maximization pro…

Dimension-Free Correlated Sampling for the Hypersimplex

Joseph, Naor, Nitya Raju +4

Sampling from multiple distributions so as to maximize overlap has been studied by statisticians since the 1950s. Since the 2000s, such correlated sampling from the probability sim…

Online Edge Coloring: Sharp Thresholds

Joakim Blikstad, Ola Svensson, Radu Vintan +1

Vizing's theorem guarantees that every graph with maximum degree admits an edge coloring using colors. In online settings - where edges arrive one at a time and must be…

Repairing Databases over Metric Spaces with Coincidence Constraints

Youri Kaminsky, Benny Kimelfeld, Ester Livshits +2

Datasets often contain values that naturally reside in a metric space: numbers, strings, geographical locations, machine-learned embeddings in a Euclidean space, and so on. We stud…
