Over mij

Ik promoveerde aan de Otto-von-Guericke Universiteit van Maagdenburg. Ik werk aan oplossende technieken voor mixed-integer programma's (MIP's) aan de praktische kant (vertakkingen en sneden, vertakkingen en prijzen) en polyhedral combinatorics aan de theoretische kant.

Expertises

Mathematics
Cutting Planes
Extended Formulations
Formulation
Linear Programming
Linear Programming Relaxation
Matroid
Polytope
Stable Set
