  • Registration: Via TUMonline 
  • Classification: "Formale Methoden und ihre Anwendungen" (FMA)

IMPORTANT NOTICE: This is a theory courseIt is expected that participants are familiar with formal mathematics and standard proof techniques. Addtionally, basic knowledge about NP-completeness is useful (e.g., Module IN0011).

Content

Social choice theory deals with the aggregation of individual preferences into a collective choice such as in voting. This course focusses on the analysis and comparison of aggregation functions that are based on simple majority rule. After introducing the mathematical and microeconomic foundations of social choice theory, particular attention will be paid to algorithmic aspects.

Tentative list of topics:

Exercises

Exercises are voluntary, but highly recommended. Each exercise sheet will contain tutorial exercises (T) and homework exercises (H). If you correctly solve at least 60 per cent of (H) exercises and pass the exam with a grade between 1.3 and 4.0, your final grade will be your exam grade minus 0.3 (for example, the grade 1.7 will be turned into 1.4).

Exercise sheets will be made available each Tuesday. They are due the following Monday at 16.00 (before the first tutorial begins). Submission is possible either via the chair's post box in the FMI basement (marked "Prof. Brandt") or at the beginning of the first tutorial.

Exam

There will be a written exam at the end of the semester, which will be graded according to the following grading scale:

  • [0,5) points: 5,0
  • [5,11) points: 4,7
  • [11,17) points: 4,3
  • [17,19] points: 4,0
  • (19,22] points: 3,7
  • (22,24] points: 3,3
  • (24,26] points: 3,0
  • (26,28] points: 2,7
  • (28,30] points: 2,3
  • (30,32] points: 2,0
  • (32,34] points: 1,7
  • (34,36] points: 1,3
  • (36,40] points: 1,0

The only resource you may use during the exam are two hand-written sheets of DIN A4 paper that you prepared yourself (you may write on both sides of each sheet). In particular, electronic devices, books, photocopies, and printouts are disallowed.

The exam will be in English. If need be, answers in German are acceptable, too.

Please remember to bring your student id (or an equivalent photo id).

We will notify you by email when the grades are available in TUMonline.

Literature

There is no textbook that covers all the topics listed above. Lecture slides will be published on a weekly basis. The 2012 survey article below informally covers many topics of this course. You can learn more about computational social choice here.
