Künstliche Intelligenz (KI) und Machine Learning (ML) gelten gegenwärtig als probate Mittel, um betriebswirtschaftliche Entscheidungen durch mathematische Modelle zu optimieren. Allerdings werden die Technologien häufig in Form von "Black Box"-Ansätze mit entsprechenden Risiken realisiert....

Dieser Beitrag vergleicht die Gerechtigkeitssemantik, die auf eine lange Tradition zurückblicken kann, mit der vergleichsweise jungen Nachhaltigkeitssemantik. Basierend auf diesem Vergleich werden drei Vorzüge der Nachhaltigkeitssemantik herausgearbeitet. Sie bestehen darin, (a) eine...

The k-traveling salesman problem, or k-TSP is: given a graph with edge weights and an integer k, find a simple cycle of minimum weight visiting exactly k nodes. To obtain lower bounds for the traveling salesman problem the 2-matching relaxation and the 1-tree relaxation can be used. We...
