Liefmannhaus, Goethestrasse 35, 79098 Freiburg im Breisgau, Germany

Aim of this small and interactive two day workshop is to bring together users and developers of algorithms for nonlinear mixed integer optimal control problems, mostly from the University of Freiburg. Besides a few external invited presentations, each participant will briefly present his/her work in the area and discuss the algorithmic progress that was achieved in the last years.
