A Vectorization Scheme for Nonconvex Set Optimization Problems
Gabriele Eichfelder, Ernest Quintana, Stefan Rocktäschel
In this paper, we study a solution approach for set optimization problems with respect to the lower set less relation. This approach can serve as a base for numerically solving set…

An algorithm for computing Fréchet means on the sphere
Gabriele Eichfelder, Thomas Hotz, Johannes Wieditz
For most optimisation methods an essential assumption is the vector space structure of the feasible set. This condition is not fulfilled if we consider optimisation problems over t…
