Position in Curriculum
Informatik (both diploma and bachelors degree), starting from 5. semester, Wahlpflichtveranstaltung (-/-/2)
Computaional Logic: Module TCSL, 3 credit points

Language
The language of the initial meeting is English unless attended by native German speakers, only. Concerning the final presentations, students may choose to present their work in German or in English.

Topic of the Hauptseminar
Many undecidable problems that are presented in computer science lectures are of a rather theoretical nature. The reason for this is not that undecidability does not arise in practice: in this seminar, we will meet several undecidable problems that occur naturally in applications. The considered applications are from the areas of operation systems security, artificial intelligence, logic, specification, and program analysis.

Participants are also invited to present their own (favorite) undecidable problems.

Goal of the Hauptseminar
Participants should learn about the relevance that theoretical computer science has for practical applications. Moreover, students should learn how to get acquainted with a relevant body of literature, how to produce a well-structured paper, and how to give an understandable talk.

Hints on how to prepare a paper and how to give a talk are available (in German).

Duties of Participants
In the initial meeting, students choose a topic to work on and are assigned a tutor. During the seminar, the student has to understand the relevant literature and writes a paper about the chosen topic (~12 pages). In doing this, he/she receives individual support by the tutor. The produced paper is required to conform to the standards of scientific writing. Finally, each student presents his/her work in a talk to the other participants.

The seminar is coordinated by Dr. Carsten Lutz
