other vertex v. This paper studies temporal design problems for undirected temporally …

[HTML][HTML] Optimizing reachability sets in temporal graphs by delaying

A Deligkas, I Potapov - Information and Computation, 2022 - Elsevier
A temporal graph is a dynamic graph where every edge is assigned a set of integer time
labels that indicate at which discrete time step the edge is available. In this paper, we study …

Given a population with dynamic pairwise connections, we ask if the entire population could …

How to reduce temporal cliques to find sparse spanners

S Angrick, B Bals, T Friedrich, H Gawendowicz… - arxiv preprint arxiv …, 2024 - arxiv.org
Many real-world networks, such as transportation or trade networks, are dynamic in the
sense that the edge set may change over time, but these changes are known in advance …

How Many Lines to Paint the City: Exact Edge-Cover in Temporal Graphs

A Deligkas, M Döring, E Eiben, TL Goldsmith… - arxiv preprint arxiv …, 2024 - arxiv.org
Logistics and transportation networks require a large amount of resources to realize

Reducing reachability in temporal graphs: Towards a more realistic model of real-world spreading processes

K Meeks - Conference on Computability in Europe, 2022 - Springer
In many settings there is a need to reduce the spread of something undesirable, such as a
virus, through a network. Typically, the network in which the spreading process takes place …

Temporal Explorability Games

P Austin, N Mazzocchi, S Bose, P Totzke - arxiv preprint arxiv:2412.16328, 2024 - arxiv.org

edges. We consider solving games played on temporal graphs where one player aims to …

Better late, then? The hardness of choosing delays to meet passenger demands in temporal graphs

DC Kutner, A Sommer - arxiv preprint arxiv:2501.18987, 2025 - arxiv.org
In train networks, carefully-chosen delays may be beneficial for certain passengers, who
would otherwise miss some connection. Given a simple temporal graph and a set of …
