Disentangling the Computational Complexity of Network Untangling
Vincent Froese, Pascal Kunz, Philipp Zschoche
We study the network untangling problem introduced by Rozenshtein, Tatti, and Gionis [DMKD 2021], which is a variant of Vertex Cover on temporal graphs -- graphs whose edge set cha…
Restless Temporal Path Parameterized Above Lower Bounds
Philipp Zschoche
Reachability questions are one of the most fundamental algorithmic primitives in temporal graphs -- graphs whose edge set changes over discrete time steps. A core problem here is t…
Interference-free Walks in Time: Temporally Disjoint Paths
Nina Klobas, George B. Mertzios, Hendrik Molter +2
We investigate the computational complexity of finding temporally disjoint paths or walks in temporal graphs. There, the edge set changes over discrete time steps and a temporal pa…
Optimal Virtual Network Embeddings for Tree Topologies
Aleksander Figiel, Leon Kellerhals, Rolf Niedermeier +3
The performance of distributed and data-centric applications often critically depends on the interconnecting network. Applications are hence modeled as virtual networks, also accou…
Parameterized Algorithms for Diverse Multistage Problems
Leon Kellerhals, Malte Renken, Philipp Zschoche
The world is rarely static -- many problems need not only be solved once but repeatedly, under changing conditions. This setting is addressed by the "multistage" view on computatio…
Temporal Reachability Minimization: Delaying vs. Deleting
Hendrik Molter, Malte Renken, Philipp Zschoche
We study spreading processes in temporal graphs, i. e., graphs whose connections change over time. These processes naturally model real-world phenomena such as infectious diseases…
