The complexity of computing optimum labelings for temporal connectivity

Nina Klobas, George B. Mertzios, Hendrik Molter +1

A graph is temporally connected if there exists a strict temporal path, i.e. a path whose edges have strictly increasing labels, from every vertex to every other vertex . In…

Delay-Robust Routes in Temporal Graphs

Eugen Füchsle, Hendrik Molter, Rolf Niedermeier +1

Most transportation networks are inherently temporal: Connections (e.g. flights, train runs) are only available at certain, scheduled times. When transporting passengers or commodi…

Temporal Connectivity: Coping with Foreseen and Unforeseen Delays

Eugen Füchsle, Hendrik Molter, Rolf Niedermeier +1

Consider planning a trip in a train network. In contrast to, say, a road network, the edges are temporal, i.e., they are only available at certain times. Another important difficul…

The Complexity of Finding Temporal Separators under Waiting Time Constraints

Hendrik Molter

In this work, we investigate the computational complexity of Restless Temporal -Separation, where we are asked whether it is possible to destroy all restless temporal paths…

Towards Classifying the Polynomial-Time Solvability of Temporal Betweenness Centrality

Maciej Rymar, Hendrik Molter, André Nichterlein +1

In static graphs, the betweenness centrality of a graph vertex measures how many times this vertex is part of a shortest path between any two graph vertices. Betweenness centrality…

On Finding Separators in Temporal Split and Permutation Graphs

Nicolas Maack, Hendrik Molter, Rolf Niedermeier +1

Removing all connections between two vertices s and z in a graph by removing a minimum number of vertices is a fundamental problem in algorithmic graph theory. This (s,z)-separatio…
