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
Constraint Satisfaction Problems
Evolutionary Algorithms, Genetic Algorithms
Answer Set Programming
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 slides of the lectures and exercises of the tutorials will be uploaded in OPAL, for each corresponding session. We invite you to use the forum to ask questions and share your exercise solutions.
