Temporal Network Creation Games: The Impact of Flexible Labels
Hans Gawendowicz, Nicolas Klodt, Aleksandrs Morgensterns +1
A crucial aspect of research is understanding how real-world networks, such as transportation and information networks, are formed. A prominent model for such networks was introduc…
Cooperation in Bilateral Generalized Network Creation
Hans Gawendowicz, Pascal Lenzner, Lukas Weyand
Studying the impact of cooperation in strategic settings is one of the cornerstones of algorithmic game theory. Intuitively, allowing more cooperation yields equilibria that are mo…
Temporal Network Creation Games: The Impact of Non-Locality and Terminals
Davide Bilò, Sarel Cohen, Tobias Friedrich +4
We live in a world full of networks where our economy, our communication, and even our social life crucially depends on them. These networks typically emerge from the interaction o…
How to Reduce Temporal Cliques to Find Sparse Spanners
Sebastian Angrick, Ben Bals, Tobias Friedrich +7
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. This be…
Temporal Network Creation Games
Davide Bilò, Sarel Cohen, Tobias Friedrich +4
Most networks are not static objects, but instead they change over time. This observation has sparked rigorous research on temporal graphs within the last years. In temporal graphs…
The Impact of Cooperation in Bilateral Network Creation
Tobias Friedrich, Hans Gawendowicz, Pascal Lenzner +1
Many real-world networks, like the Internet, are not the result of central design but instead the outcome of the interaction of local agents who are selfishly optimizing for their…
Social Distancing Network Creation
Tobias Friedrich, Hans Gawendowicz, Pascal Lenzner +1
During a pandemic people have to find a trade-off between meeting others and staying safely at home. While meeting others is pleasant, it also increases the risk of infection. We c…
Efficiency and Stability in Euclidean Network Design
Wilhelm Friedemann, Tobias Friedrich, Hans Gawendowicz +5
Network Design problems typically ask for a minimum cost sub-network from a given host network. This classical point-of-view assumes a central authority enforcing the optimum solut…
