On the structure of unique shortest paths in graphs

G Bodwin - Proceedings of the Thirtieth Annual ACM-SIAM …, 2019 - SIAM
This paper develops a structural theory of unique shortest paths in real-weighted graphs.
Our main goal is to characterize exactly which sets of node sequences, which we call path …

A simple algorithm for graph reconstruction

C Mathieu, H Zhou - Random Structures & Algorithms, 2023 - Wiley Online Library
How efficiently can we find an unknown graph using distance queries between its vertices?
We assume that the unknown graph is connected, unweighted, and has bounded degree …

Graph reconstruction and verification

S Kannan, C Mathieu, H Zhou - ACM Transactions on Algorithms (TALG), 2018 - dl.acm.org
How efficiently can we find an unknown graph using distance or shortest path queries
between its vertices? We assume that the unknown graph G is connected, unweighted, and …

Reconstruction and verification of chordal graphs with a distance oracle

G Rong, W Li, Y Yang, J Wang - Theoretical Computer Science, 2021 - Elsevier
A hidden graph is a graph whose edge set is hidden. A distance oracle of a graph G is a
black-box that receives two vertices of G and outputs the distance between the two vertices …

Optimal distance query reconstruction for graphs without long induced cycles

P Bastide, C Groenland - arXiv preprint arXiv:2306.05979, 2023 - arxiv.org
Let $ G=(V, E) $ be an $ n $-vertex connected graph of maximum degree $\Delta $. Given
access to $ V $ and an oracle that given two vertices $ u, v\in V $, returns the shortest path …

Tight query complexity bounds for learning graph partitions

X Liu, S Mukherjee - Conference on Learning Theory, 2022 - proceedings.mlr.press
Given a partition of a graph into connected components, the membership oracle asserts
whether any two vertices of the graph lie in the same component or not. We prove that for …

Parallel network mapping algorithms

R Afshar, MT Goodrich, P Matias… - Proceedings of the 33rd …, 2021 - dl.acm.org
Motivated from parallel network mapping, we provide efficient query complexity and round
complexity bounds for graph reconstruction using distance queries, including a bound that …

Learning Hypertrees From Shortest Path Queries

SM Fallat, V Maliuk, SA Mojallal… - … on Algorithmic Learning …, 2024 - proceedings.mlr.press
We consider the problem of learning a labeled hypergraph from a given family of
hypergraphs, using shortest path (SP) queries. An SP query specifies two vertices and asks …

Finding mnemon: Reviving memories of node embeddings

Y Shen, Y Han, Z Zhang, M Chen, T Yu… - Proceedings of the …, 2022 - dl.acm.org
Previous security research efforts orbiting around graphs have been exclusively focusing on
either (de-) anonymizing the graphs or understanding the security and privacy issues of …

Exact learning of multitrees and almost-trees using path queries

R Afshar, MT Goodrich - Latin American Symposium on Theoretical …, 2022 - Springer
Given a directed graph, G=(V, E), a path query, path (u, v), returns whether there is a
directed path from u to v in G, for u, v∈ V. Given only V, exactly learning all the edges in G …
