Compact Course: Complexity Reducing Formulations in Optimization

The main goal of this compact course (LSF entry) is to provide insight into the foundations and the state-of-the-art of the research area Complexity Reducing Formulations in Optimization. To this end, the foundations will be taught in a tutorial part with hands-on practical exercises. Participants are kindly asked to bring their own notebooks with a Matlab or Octave installation. The five day tutorial part will also include insight into Magdeburg state-of-the-art projects in the field of algebra, discrete geometry, optimization, and optimal control.
