Bridge girth: A unifying notion in network design

G Bodwin, G Hoppenworth… - 2023 IEEE 64th Annual …, 2023 - ieeexplore.ieee.org
A classic 1993 paper by Althöfer et al. proved a tight reduction from spanners, emulators,
and distance oracles to the extremal function γ of high-girth graphs. This paper initiated a …

Better distance preservers and additive spanners

G Bodwin, VV Williams - Proceedings of the twenty-seventh annual ACM …, 2016 - SIAM
We make improvements to the upper bounds on several popular types of distance
preserving graph sketches. The first part of our paper concerns pairwise distance …

New results on linear size distance preservers

G Bodwin - SIAM Journal on Computing, 2021 - SIAM
Given p node pairs in an n-node graph, a distance preserver is a sparse subgraph that
agrees with the original graph on all of the given pairwise distances. We prove the following …

Linear size distance preservers

G Bodwin - Proceedings of the Twenty-Eighth Annual ACM-SIAM …, 2017 - SIAM
The famous shortest path tree lemma states that, for any node s in a graph G=(V, E), there is
a subgraph on O (n) edges that preserves all distances between node pairs in the set {s}× V …

Differentially private all-pairs shortest path distances: Improved algorithms and lower bounds

JY Chen, B Ghazi, R Kumar, P Manurangsi… - Proceedings of the 2023 …, 2023 - SIAM
We study the problem of releasing the weights of all-pairs shortest paths in a weighted
undirected graph with differential privacy (DP). In this setting, the underlying graph is fixed …

The discrepancy of shortest paths

G Bodwin, C Deng, J Gao, G Hoppenworth… - arXiv preprint arXiv …, 2024 - arxiv.org
The hereditary discrepancy of a set system is a certain quantitative measure of the
pseudorandom properties of the system. Roughly, hereditary discrepancy measures how …
