Computational Social Dynamics (Dagstuhl Seminar 22452)

Authors: Martin Hoefer, Sigal Oren, Roger Wattenhofer, and Giovanna Varricchio


Abstract
This report documents the program and outcomes of Dagstuhl Seminar 22452 "Computational Social Dynamics". The seminar addressed social and dynamic problems in the field of algorithmic game theory, and their implications in numerous applications, such as fair division, financial networks, or behavioral game theory. We summarize organizational aspects of the seminar, the talk abstracts, and the problems that were discussed in the open problem sessions.

Dynamic Graph Algorithms (Dagstuhl Seminar 22461)

Authors: Aaron Bernstein, Shiri Chechik, Sebastian Forster, Tsvi Kopelowitz, Yasamin Nazari, and Nicole Wein


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 22461 “Dynamic Graph Algorithms”, which took place from November 13 to November 18, 2022. The field of dynamic graph algorithms studies algorithms for processing graphs that are changing over time. Formally, the goal is to process an interleaved sequence of update and query operations, where an update operation changes the input graph (e.g. inserts/deletes an edge), while the query operation is problem-specific and asks for some information about the current graph – for example, an s-t path, or a minimum spanning tree. The field has evolved rapidly over the past decade, and this Dagstuhl Seminar brought together leading researchers in dynamic algorithms and related areas of graph algorithms.

Set Visualization and Uncertainty (Dagstuhl Seminar 22462)

Authors: Susanne Bleisch, Steven Chaplick, Jan-Henrik Haunert, Eva Mayr, Marc van Kreveld, and Annika Bonerath


Abstract
The Dagstuhl Seminar on Set Visualization and Uncertainty brought together a group of researchers from diverse disciplines, all of which are interested in various aspects of this type of visualization: the cognitive aspects, the modelling aspects, the algorithmic aspects, and the information visualization aspects. An important but difficult to handle problem is how one should visualize information with underlying uncertainty. The seminar focused on uncertainty in set systems. This report includes short abstracts of the talks given during the seminar as well as more extensive working group reports on the research done during the seminar.

Towards More Flexible and Automated Communication Networks (Dagstuhl Seminar 22471)

Authors: Artur Hecker, Stefan Schmid, Henning Schulzrinne, Lily Hügerich, Sándor Laki, and Iosif Salem


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 22471 "Towards More Flexible and Automated Communication Networks". Communication network are becoming more and more automated, allowing to overcome human configuration errors (a frequent reason for outages) and enabling a more fine-grained control, potentially improving also efficiency. For example, the percentage of employees of Telecom companies "really touching the network" is decreasing. The goal of this seminar was to bring together experts in the field to identify and discuss the key challenges in making communication networks more autonomous. To this end, the seminar was structured around a small number of enlightning keynote talks, leaving significant time for breakout sessions and discussions, as well as socializing.
