Theoretical Computer Science - Bridging Course
Graduate Course -Summer Term 2025
Fabian Kuhn
Course Description
The aim of the course is to provide basic knowledge of theoretical computer science to computer science M.Sc. students who do not yet have this necessary background (e.g., because of a different major during their undergraduate studies). The course introduces the (mathematical) foundations of theoretical computer science. We will see what can be computed and how efficiently, as well as what cannot. More specifically, the following topics will be included:
- Automata
- Formal languages
- Formal grammars
- Turing machines
- Decidability
- Complexity theory
- Logic
Course Format
The course is based on existing recordings provided by Diego Tipaldi combined with weekly interactive exercise lessons. This will prepare the participants for the final exam.
Schedule
In conjunction with the the recorded lecture we offer weekly exercise lessons. The exercise lessons will take place in person every Tuesday at 12:15 - 14:00 in seminar room 51-00-031.
Announcement
There will be an introductory session in the first week of the semester on Tuesday, 22.04.2025 at 12:15 in seminar room 51-00-031.
Data Access
Zulip: An instant messaging platform (Zulip) is offered for all students to discuss any issues related to the course whether among themselves or with the tutor. To join Zulip, click on the invitation link which is also given here.
Important note: The link on how to join Zulip can only be accessed from within the university network (i.e., use VPN to access the page from home or access the internet via the university eduroam).

Exercise Material
You will be provided with an exercise sheet every week here on the website, which you should work on at home after watching the assigned lecture(s), and the solutions will be discussed in the exercise lessons. It is not mandatory to submit solutions. However in case you wish to get feedback on your written solutions (whether using Latex, Word, or legible handwritten scans), send your solutions to your assigned tutor Salwa Faour by the given deadlines.
