Sampling hypergraphs with given degrees

M Dyer, C Greenhill, P Kleer, J Ross, L Stougie - Discrete Mathematics, 2021 - Elsevier
There is a well-known connection between hypergraphs and bipartite graphs, obtained by
treating the incidence matrix of the hypergraph as the biadjacency matrix of a bipartite …

[HTML][HTML] The mixing time of switch Markov chains: a unified approach

PL Erdős, C Greenhill, TR Mezei, I Miklós… - European Journal of …, 2022 - Elsevier
Since 1997 a considerable effort has been spent to study the mixing time of switch Markov

Generating graphs randomly

C Greenhill - arXiv preprint arXiv:2201.04888, 2022 - arxiv.org
Graphs are used in many disciplines to model the relationships that exist between objects in
a complex discrete system. Researchers may wish to compare a network of interest to a" …

Mixing time of the switch Markov chain and stable degree sequences

P Gao, C Greenhill - Discrete Applied Mathematics, 2021 - Elsevier
The switch chain is a well-studied Markov chain which can be used to sample approximately
uniformly from the set Ω (d) of all graphs with a given degree sequence d. Polynomial mixing …

Rapid mixing of the switch Markov chain for strongly stable degree sequences

G Amanatidis, P Kleer - Random Structures & Algorithms, 2020 - Wiley Online Library

Monte Carlo approach for sampling graphs with prescribed degree sequences. We show …

Subexponential mixing for partition chains on grid-like graphs

A Frieze, W Pegden - Proceedings of the 2023 Annual ACM-SIAM …, 2023 - SIAM
We consider the problem of generating uniformly random partitions of the vertex set of a

Sharp Poincaré and log-Sobolev inequalities for the switch chain on regular bipartite graphs

K Tikhomirov, P Youssef - Probability Theory and Related Fields, 2023 - Springer
Consider the switch chain on the set of d-regular bipartite graphs on n vertices with 3≤ d≤

Half-graphs, other non-stable degree sequences, and the switch Markov chain

PL Erdős, E Győri, TR Mezei, I Miklós… - arXiv preprint arXiv …, 2019 - arxiv.org
One of the simplest methods of generating a random graph with a given degree sequence is
