Sailing League Problems
Robert Schüler, Achill Schürmann
We describe a class of combinatorial design problems which typically occur in professional sailing league competitions. We discuss connections to resolvable block designs and equit…
A simplex algorithm for rational cp-factorization
Mathieu Dutour Sikirić, Achill Schürmann, Frank Vallentin
In this paper we provide an algorithm, similar to the simplex algorithm, which determines a rational cp-factorization of a given matrix, whenever the matrix allows such a factoriza…
Exploiting Symmetry in Integer Convex Optimization using Core Points
Katrin Herr, Thomas Rehn, Achill Schürmann
We consider convex programming problems with integrality constraints that are invariant under a linear symmetry group. To decompose such problems we introduce the new concept of co…
