Ziawasch Abedjan and Ulrich Meyer have been guest-editing a new Special Issue of Algorithms for Big Data appearing soon in it - Information Technology. It contains several articles from reseachers working at the Berlin Big Data Center / BIFOLD and the DFG SPP 1736 Priority Programme on Algorithms for Big Data. Group members Manuel Penschuck and Ulrich Meyer contributed an update on Large-Scale Graph Generation.

The German Research Foundation grants funding for a new research group on Algorithms, Dynamics, and Information Flow in Networks. The group is headed by Martin Hoefer, the participating PIs are Petra Berenbrink (Hamburg), Nils Bertschinger, Amin Coja Oghlan, Ulrich Meyer (all Frankfurt/M), and Tobias Friedrich (HPI/Potsdam). The goals are to advance our understanding of dynamic processes on networks and their relation to efficient algorithms, e.g., in the analysis of spreading processes, distributed network algorithms, network generation models, as well as application domains such as financial markets.

David Veith successfully defended his PhD thesis on graph algorithms for approximate and dynamic settings in the external-memory model. Congrats, Dr. Veith!!! David has moved on to industry and is currently working with Dematic.

Ulrich Meyer (together with Peter Sanders from KIT) will be awarded the Test-of-Time Award of the European Symposium on Algorithms 2019 (ESA) at ESA 2020.
ESA is the premier European conference on algorithms research. The ESA Test-of-Time Award (ToTA) recognizes excellent papers in algorithms research that were published in the ESA proceedings 19 to 21 years ago which are still influential and stimulating for the field today. For 2019, the Award Committee selected
