  • Credits: 3.0
  • Type: VU Lecture and Exercise
  • Format: Distance Learning

Learning outcomes

After successful completion of the course, students are able to

  • explain fundamental concepts, structures and problem definitions in algorithmic geometry
  • explain, assess, and analyze the discussed algorithms
  • select and adapt appropriate algorithms and data structures to related problems
  • model and analyze unknown applied or theoretical geometric problems and develop and possibly implement efficient solutions independently

Subject of course

Spatial data are processed in various subfields of computer science, e.g. in computer graphics, visualization, geographic information systems, robotics etc. The area of computational geometry deals with the design and analysis of geometric algorithms and data structures. In this module we present common techniques and concepts in computational geometry in the context of selected and applied geometric questions. The following topics are covered in the course:

  • convex hulls
  • line segment intersections
  • polygon triangulation
  • range queries
  • point location
  • Voronoi diagrams and Delaunay triangulations
  • duality of points and lines
  • quadtrees
  • well-separated pair decomposition
  • visibility graphs

Teaching methods

  • Definition, design and analysis of algorithms and data structures, discussion and formal proofs of algorithmic and geometric properties, examples
  • Joint and independent solving of exercise and example tasks
  • Discussion of exercise tasks and proof ideas in (virtual) exercise groups
  • Lecture content will be provided weekly as recorded videos; live discussions will help consolidating the material.

Additional information

Distance Learning

This course takes place in "distance learning" mode. We provide learning videos once per week, which can be watched asynchronously. The exercise part consists of multiple exercise sheets to be solved and handed in. Further we will offer electronic live meetings every few weeks to discuss and deepen the course material (Tuesdays from 9:00-11:00). Finally, we use quizzes and discussion forums in TUWEL.

The firs lecture takes place live on October 6, 2020 from 9:00-11:00 in Zoom. The Zoom URL will be announced to all registered students before the first lecture.
