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…

The Complexity of Transitively Orienting Temporal Graphs

George B. Mertzios, Hendrik Molter, Malte Renken +2

In a temporal network with discrete time-labels on its edges, entities and information can only ``flow'' along sequences of edges whose time-labels are non-decreasing (resp. increa…
