As part of the ADYN project, our group hosted this year's edition of the ADYN summer school. Taking place from 19-22 September, it attracted 70 participants from all over Europe. All of the exciting lectures by Hannah Bast, Thomas Bläsius, Gerth Stølting Brodal, Michael Fellows, Giuseppe F. Italiano, Riko Jacob, Henning Meyerhenke and Francesco Silvestri were recorded and are available here. Finally, for the social event, we had a boat tour around the scenic lakes and castles of Potsdam.
