Coloring fast with broadcasts

M Flin, M Ghaffari, MM Halldórsson, F Kuhn… - Proceedings of the 35th …, 2023 - dl.acm.org
We present an O (log3 log n)-round distributed algorithm for the (Δ+ 1)-coloring problem,
where each node broadcasts only one O (log n)-bit message per round to its neighbors …

Fast coloring despite congested relays

M Flin, MM Halldórsson, A Nolin - arXiv preprint arXiv:2308.01359, 2023 - arxiv.org
We provide a $ O (\log^ 6\log n) $-round randomized algorithm for distance-2 coloring in

Decentralized distributed graph coloring II: degree+ 1-coloring virtual graphs

M Flin, MM Halldórsson, A Nolin - arXiv preprint arXiv:2408.11041, 2024 - arxiv.org
Graph coloring is fundamental to distributed computing. We give the first general treatment
of the coloring of virtual graphs, where the graph $ H $ to be colored is locally embedded …

Decentralized Distributed Graph Coloring: Cluster Graphs

M Flin, MM Halldorsson, A Nolin - arXiv preprint arXiv:2405.07725, 2024 - arxiv.org
Graph coloring is fundamental to distributed computing. We give an ultrafast distributed
algorithm for coloring cluster graphs. These graphs are obtained from the underlying …

Colouring graphs from random lists

D Hefetz, M Krivelevich - arXiv preprint arXiv:2402.09998, 2024 - arxiv.org
Given positive integers $ k\leq m $ and a graph $ G $, a family of lists $ L=\{L (v): v\in V (G)\}
$ is said to be a random $(k, m) $-list-assignment if for every $ v\in V (G) $ the list $ L (v) $ is …
