The INFORMS awards the George B. Dantzig Dissertation Award for outstanding dissertations on the interaction between academia and industry. Awardees have demonstrated innovative research relevant to practice in operations research or management science. Daniel Rehfeldt made it to the finals of 2022 for his thesis on “Faster algorithms for Steiner tree and related problems: From theory to practice.” The other finalists were Anish Agarwal (MIT), Ruihao Zhu (MIT), and Su Jia (Carnegie Mellon University), who was awarded for his thesis...Read More
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...Read More
The German Operations Research Society (GOR) awards an annual prize for outstanding dissertations in the field of Operations Research. One of the 2022 awardees is Daniel Rehfeldt for his thesis on “Faster algorithms for Steiner tree and related problems: From theory to practice.” The prize was awarded this year at the general meeting of the GOR at the KIT in Karlsruhe. The Steiner tree problem in graphs (SPG) is one of the most studied problems in combinatorial optimization. Many applications...Read More
