Investigating mixed-integer programming approaches for the --closest-center problem
Elisabeth Gaar, Sara Joosten, Markus Sinnl
In this work, we introduce and study the --closest-center problem (CCP), which generalizes the -second-center problem, a recently emerged variant of the classical -…
The Bi-objective Electric Autonomous Dial-a-Ride Problem
Yue Su, Sophie N. Parragh, Nicolas Dupin +1
The electric autonomous dial-a-ride problem (E-ADARP) introduces electric, autonomously driving vehicles and their unique requirements into the classic dial-a-ride problem, where p…
The exact subgraph hierarchy and its vertex-transitive variant for the stable set problem for Paley graphs
Elisabeth Gaar, Dunja Pucher
The stability number of a graph, defined as the cardinality of the largest set of pairwise non-adjacent vertices, is NP-hard to compute. The exact subgraph hierarchy (ESH) provides…
Duality of Geometric Tests for Forward-Flatness
Johannes Schrotshamer, Bernd Kolar, Markus Schöberl
Recently it has been shown that the property of forward-flatness for discrete-time systems, which is a generalization of static feedback linearizability and a special case of a mor…
Staggered Routing in Autonomous Mobility-on-Demand Systems
Antonio Coppola, Gerhard Hiermann, Dario Paccagnan +1
In autonomous mobility-on-demand systems, effectively managing vehicle flows to mitigate induced congestion and ensure efficient operations is imperative for system performance and…
A Dual Geometric Test for Forward-Flatness
Bernd Kolar, Johannes Schrotshamer, Markus Schöberl
Forward-flatness is a generalization of static feedback linearizability and a special case of a more general flatness concept for discrete-time systems. Recently, it has been shown…
