For HISPOS, this must be done until one week before the exam at the latest (February 7). We will keep CMS open until the end of this week. 1) CMS: We have just opened the registration in CMS. Please be aware that you will only be able to register if you have enough points in the programming projects. 2) HISPOS/VIPA: This depends on your course of studies. You should know if your course of studies is using one of these. If so, you need to register in the corresponding system. Students in course of studies that belong to HISPOS or VIPA and don't register there will not be allowed to take the exam. If you cannot register in HISPOS or VIPA, please write me (hoeller@cs.uni-saarland.de) once you register in CMS so that we keep track of the list of students that attend the exam without being in HISPOS or VIPA. The exam is on the 15. February in HS003 in E1.3. at 9:00. The lecture on exam preparation on Wednesday will be in person in E 1.1 Seminar room 3.06. Best regards, |

AI Planning
AI Planning is one of the fundamental sub-areas of Artificial Intelligence, concerned with algorithms that can generate strategies of action for arbitrary autonomous agents in arbitrary environments. The course will address so-called classical planning, where the actions and environment are assumed to be deterministic; this is a central area in planning, and has been the source of many influential ideas. It is also successfully applied in practice, as we will exemplify in the course. We will examine the technical core of the current research on solving this kind of problem. We will consider four different paradigms for automatically generating heuristic functions (lower bound solution cost estimators): critical paths, ignoring delete lists, abstractions, landmarks. Apart from understanding these techniques themselves, we will learn how to analyze, combine, and compare such estimators. The course contains many research results from the last decade, close to the current research frontier in planning.
Prerequisites. Ideally, participating students should have successfully completed an introductory course in Artificial Intelligence. However, the course is self-contained and any student with a solid basis in Computer Science – algorithms, data structures, programming, propositional logic, NP-hardness – should in principle be able to follow. Prior knowledge about search (the A* algorithm etc) is an advantage. Students who have already passed Automatic Planning in previous years are not allowed to attend the course.
