Title: Operations Research in Land Exchange


With geometric modeling techniques, one can represent the feasible solutions of problems in operations research as objects in high-dimensional space. The properties of these objects reveal information about the underlying problems and lead to algorithms.

We model an application in land exchange as a clustering problem where the clusters have to adhere to prescribed cluster sizes. In this approach, we connect least-squares assignments, cell complexes, and the studies of polyhedra. Further, we report on how these results were implemented in practice. The devised methods lead to various tools for more general questions on big data.


Steffen Borgwardt is a new assistant professor in the math department of CU Denver. His area of research is applied discrete mathematics and optimization, studying high-dimensional geometric objects arising in operations research.

He earned his PhD in 2010 and holds a habilitation on "Data Analytics through Polyhedral Theory" from TU Munich. Before coming to Denver, he held several visiting assistant professor positions, in particular at UC Davis through a Feodor Lynen scholarship of the Humboldt Foundation.

Today, he reports on a project that received the European Excellence in Practice Award 2013, awarded by EURO, the Association of European Operational Research Societies within IFORS.
