Enrico Bortoletto, Niels Lindner and Berenike Masing (ZIB MobilityLab) have received the Best Paper Award at ATMOS 2022. Their contribution "Tropical Neighbourhood Search: A New Heuristic for Periodic Timetabling" introduces a novel algorithm for optimizing periodic timetables in public transport using the techniques of tropical geometry. ATMOS 2022, the 22nd Symposium on Algorithmic Approaches for Transportation Modelling, Optimization, and Systems, is an international forum for researchers in the area of algorithms and optimization methods to facilitate planning and operational management of freight and passenger transportation and traffic. The conference took place on September 8-9, 2022, in Potsdam, Germany, and is part of ALGO, the major European event for researchers, students and practitioners in algorithms.
