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)


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 practical part, the students will analyze a given problem and develop a solution for it.

Prerequisites

Basice knowledge of theoretical computer science and Logic.

Organisation

The goals can be acquierd by studying the lecture material, solving the exercises of the tutorials and developing an implementation for a practical problem.

The lecture is scheduled for Friday DS4 13:00-14:30 in room APB E005 and the tutorial will be held on Tuesday DS5 14:50-16:20 in room APB E007 (see the exact schedule). The practical work should be performed in groups of two students throughout the semester with regular updates on the progress.

The first lecture will be on Friday 7th April 2017, DS4 13:00-14:30 in room APB E005.

Note: the lecture on Friday 16th June 2017 will be held in room APB 2026.
