In this seminar we will study several modeling and reasoning techniques for knowledge and belief in dynamic systems. Knowledge is an important aspect of intelligent programs: while most of today’s systems assume a closed world, i.e., everything they don’t know to be true is assumed to be false, an intelligent system needs to consider possible that there are truths not known to the system. In a dynamic environment, i.e., an environment where one or multiple agents (inter)act, the system will usually have to acquire new knowledge through sensing. Potentially it may even revise its beliefs when it realizes some beliefs were wrong. In this seminar we will study various aspects of action, knowledge, and belief.
We plan to implement a peer review process for this seminar. That is, every student will read some other students’ term paper and provide feedback in form of a written review. This shall not only deepen your understanding of the other topics, but it also introduces you to the academic review process.
Students of Bachelor and Master programs can participate in this seminar. For Master Informatik students, the seminar belongs to the fields Theoretische Informatik and Daten- und Informationsmanagement. For Master Software Systems Engineering (SSE) students, it belongs to the fields Theoretical Foundations of SSE and Data and Information Management.
Places are allocated centrally from 14.01.2014 until 26.01.2014. Please clearly indicate why you want to join this particular seminar and your prior knowledge of the subject within the above mentioned registration process. We won’t be able to consider your application otherwise. The number of available slots is limited.
A thorough knowledge of logic and knowledge representation is absolutely essential. Relevant courses include the Mathematical Logic course from the Mathematical Foundations of Computer Science group and our lectures on Knowledge Representation.

- Continual Planning:
- Conformant Planning:
- The date and time for the introductory meeting will be announced here. Participation is compulsory.
- Besides writing your own term paper, you are asked to review other students’ term papers. We will use a conference management system (e.g., EasyChair) for this procedure. It will involve strict deadlines. Meeting these deadlines is mandatory. At the end of the seminar each student needs to give a talk on his topic in front of the other students and members of our group. Attendance of these talks and participation in the discussions is mandatory.
- The seminar will be held as a block seminar on two or three days, likely during the semester break.
- You may use this LaTeX template for your term paper.
- Please read and understand our general information and suggestions on seminars!
- The Computer Science Library offers guided tours on how to find literature in the library and how to prepare a seminar. Interested students should enlist for a tour in the preliminary discussion.
