Teaching methods
The course contains
  • 14  lecture sessions.
  • 5 exercice sessions.
Evaluation methods
The exam is individual and written. The questions are based on the objectives described above and focus on the understanding and ability to explain the various concepts taught during the course (as opposed to pure memorization). The exam duration is around 3 hours.
