Problem solving and search is a central topic in Artificial Intelligence. This course presents several techniques to solve in general difficult problems.
The course covers the following topics:
- Basic Concepts
- Uninformed vs Informed Search
- Local Search, Stochastic Hill Climbing, Simulated Annealing
- Tabu Search
- Answer Set Programming
- Constraint Satisfaction
- Evolutionary Algorithms, Genetic Algorithms
- Structural Decomposition Techniques (Tree/Hypertree Decompositions)
The course does not cover topics in the area of Machine Learning and Neural Networks.
NOTE: This course was previously named Problem Solving and Search in Artificial Intelligence. The contents of former PSSAI and APSS are identical, and therefore students can only take one of the two courses.
Learning Outcomes
- The students should identify why typical AI problems are difficult to solve
- The students will analyze different algorithms and methods for AI problems and identify when their application is appropriate
- The connections between the (graph) structure and the complexity of a problem should become clear, as well as which methods can be used to tackle the problem
- In the tutorials, the students will analyze different problems and develop solutions for them.
Prerequisites
- Basic knowledge of theoretical computer science and Logic.
- Good English skills: both the teaching and examination will be exclusively in English.
Organisation
The goals can be acquired by studying the lecture material and solving the exercises of the tutorials.
The lectures will be held on Mondays DS1 (07.30 - 09.00 am) and the tutorials on Mondays DS2 (09.20 - 10.50 am). Please check the schedule for changes. The lectures will consist of videos and other materials that will be uploaded online. The tutorials will be online live sessions via BigBlueButton (no recordings of these sessions will be uploaded).
The slides of the lectures and exercises of the tutorials will be uploaded in OPAL, for each corresponding session. The lecture videos will also be uploaded in OPAL and I invite you to use the forum to ask questions and share your exercise solutions.
