Penalty Alternating Direction Methods for Mixed-Integer Optimization: A New View on Feasibility Pumps
Björn Geißler, Antonio Morsi, Lars Schewe +1
Feasibility pumps are highly effective primal heuristics for mixed-integer linear and nonlinear optimization. However, despite their success in practice there are only few works co…

Non-Realizable Minimal Vertex Triangulations of Surfaces: Showing Non-Realizability using Oriented Matroids and Satisfiability Solvers
Lars Schewe
We show that no minimal vertex triangulation of a closed, connected, orientable 2-manifold of genus 6 admits a polyhedral embedding in R^3. We also provide examples of minimal vert…

There are no realizable 15_4- and 16_4-configurations
Juergen Bokowski, Lars Schewe
There exist a finite number of natural numbers n for which we do not know whether a realizable n_4-configuration does exist. We settle the two smallest unknown cases n=15 and n=16.…
