Sparse outerstring graphs have logarithmic treewidth

S An, E Oh, J Xue - arXiv preprint arXiv:2406.17424, 2024 - arxiv.org
An outerstring graph is the intersection graph of curves lying inside a disk with one endpoint
on the boundary of the disk. We show that an outerstring graph with $ n $ vertices has …

Cops and robbers on directed and undirected abelian Cayley graphs

P Bradshaw, SA Hosseini, J Turcotte - European Journal of Combinatorics, 2021 - Elsevier
We show that the cop number of directed and undirected Cayley graphs on abelian groups
is in O (n), where n is the number of vertices, by introducing a refined inductive method. With …

On the cop number of string graphs

S Das, H Gahlawat - arXiv preprint arXiv:2408.11002, 2024 - arxiv.org
Cops and Robber is a well-studied two-player pursuit-evasion game played on a graph,
where a group of cops tries to capture the robber. The\emph {cop number} of a graph is the …

[HTML][HTML] Greedy strategies and larger islands of tractability for conjunctive queries and constraint satisfaction problems

G Greco, F Scarcello - Information and Computation, 2017 - Elsevier
Most structural decomposition methods can be characterized through hypergraph games
that are variations of the Robber and Cops graph game that characterizes the notion of …

Pursuit-evasion in graphs: Zombies, lazy zombies and a survivor

P Bose, JL De Carufel, T Shermer - arXiv preprint arXiv:2204.11926, 2022 - arxiv.org
We study zombies and survivor, a variant of the game of cops and robber on graphs. In this
variant, the single survivor plays the role of the robber and attempts to escape from the …

Cops and Robber on butterflies, grids, and AT-free graphs

SS Akhtar, S Das, H Gahlawat - Discrete Applied Mathematics, 2024 - Elsevier
Cops and Robber is a well-studied two player pursuit-evasion game played on a graph. In
this game, a set of cops, controlled by the first player, tries to capture the position of a robber …

On strict (outer-) confluent graphs

H Förster, R Ganian, F Klute, M Nöllenburg - International Symposium on …, 2019 - Springer
A strict confluent (SC) graph drawing is a drawing of a graph with vertices as points in the
plane, where vertex adjacencies are represented not by individual curves but rather by …

The Cops and Robber game on some graph classes

H Gahlawat - 2022 - dspace.isical.ac.in
Cops and Robber is a two-player pursuit-evasion game played on graphs. Here, one player
controls a set of k cops, and the other player controls a single robber. The game starts with k …
