| Inhalt | Geometric algorithms are of fundamental interest for a large spectrum of topics, both from theory and practice. In this class, we will start from the basic foundations, and work our way towards advanced topics.
In this semester, we will try a special online format, with participant from different countries, giving us the opportunity to do international exchange in the same classroom. We will discuss how to make the best of this opportunity - so feel free to bring in new ideas and suggestions. Topics are: - Geometric problems and data structures
- Convex hulls
- Closest pairs
- Voronoi diagrams
- Polygon triangulation
- Point triangulation
- Location problems
- Tours and polygons
