Students need to successfully participate in the exercise sessions, according to the regulations below, in order to get admitted to the final exam. 

  • There will be 6 exercise sheets.
  • The teaching assistant presents the solutions and answers questions.
  • There is no mandatory attendance of the exercise sessions; still, we would be happy to see a lively participation.
  • Each sheet consists of 3 assignments, which makes 18 assignments in total. Each assignment is equivalent to one point.
  • A student needs to reach a total of at least 13 points throughout the semester to qualify for the final exam.
  • Solutions to exercise sheets have to be submitted in OLAT.
  • Students can work alone or in groups of max. two, determined with the first submission, and upload, individually, the same solution in OLAT, with names of both members on all sheets.
  • Students need to mark in OLAT which individual assignments they have managed to solve correctly.
  • Students can only mark an assignment as solved, if they have managed to complete more than ⅔ of the assignment.
  • If the solution of an assignment is not done correctly to an extent of ⅔ or more, the point for that assignment will be not given. That means, if you did not work on more than ⅔, don’t put the mark at all.
  • If it is obvious that the mark has been placed in a dishonest attempt to obtain a point without proper engagement with the assignment, the entire sheet is assessed with zero points. For instance, if the marked exercise is not done at all or clearly below ⅔ solved.
  • Copying solutions from other groups or taking solutions from previously published solution sheets, if clearly identifiable, will cause all involved groups to get immediately disqualified from the course, independent of the number of points accomplished regularly.

Exercise Sheets

If you are using Latex to prepare your submission, you might find the Latex sources of the sheets useful. But do not expect that these compile; just copy the parts you need.
