Risk management in multi-objective portfolio optimization under uncertainty
Yannick Becker, Pascal Halffmann, Anita Schöbel
In portfolio optimization, decision makers face difficulties from uncertainties inherent in real-world scenarios. These uncertainties significantly influence portfolio outcomes in…
Location problems with cutoff
Raoul Müller, Anita Schöbel, Dominic Schuhmacher
In this paper we study a generalized version of the Weber problem of finding a point that minimizes the sum of its distances to a finite number of given points. In our setting thes…
Estimating the Robustness of Public Transport Systems Using Machine Learning
Matthias Müller-Hannemann, Ralf Rückert, Alexander Schiewe +1
The planning of attractive and cost efficient public transport systems is a highly complex optimization process involving many steps. Integrating robustness from a passenger's poin…
Multi-objective minmax robust combinatorial optimization with cardinality-constrained uncertainty
Andrea Raith, Marie Schmidt, Anita Schöbel +1
In this paper we develop two approaches to find minmax robust efficient solutions for multi-objective combinatorial optimization problems with cardinality-constrained uncertainty.…
Algorithm Engineering in Robust Optimization
Marc Goerigk, Anita Schöbel
Robust optimization is a young and emerging field of research having received a considerable increase of interest over the last decade. In this paper, we argue that the the algorit…
Norm Bounds and Underestimators for Unconstrained Polynomial Integer Minimization
Sönke Behrends, Ruth Hübner, Anita Schöbel
We consider the problem of minimizing a polynomial function over the integer lattice. Though impossible in general, we use a known sufficient condition for the existence of continu…
Locating Two Transfer Points on a Network with a Trip Covering Criterion and Mixed Distances
M. C. López-de-los-Mozos, Juan A. Mesa, Anita Schöbel
In this paper we consider a set of origin-destination pairs in a mixed model in which a network embedded in the plane represents an alternative high-speed transportation system, an…
