**General description**: The main objective of the module is to impress upon students that computer science is an applied science that attempts to bridge the gap between man and machines. The module includes both foundations and applications of AI. The tremendous advances of computing have not yet fully materialized into seamless communication with humans in natural language or into generic learning, though a wide array of applications has been fielded with success. Since Artificial Intelligence does aim to empower machines with traits or features of human intelligence, there is a strong incentive to study the techniques and the processes that allow a computer to display behaviour that resembles that of human beings, in a variety of contexts. The module starts by covering fundamental concepts in state space representations and search for problem solving, constraints handling and adversarial search. It then moves on to aspects of knowledge representation and reasoning with first-order logic and complements the treatment with an introduction to logic programming (with Prolog). It then moves on to deal with learning, placing an emphasis on neural networks (but, also, covering decision trees and clustering), and then moves on to genetic/evolutionary algorithms and genetic programming, presenting them as a stochastic search technique that can be used for a variety of optimization problems. Finally, hybrid algorithms are presented that combine the last two technologies in order to alleviate their disadvantages and enforce their advantages. Besides the theoretical treatment, students are also introduced to a variety of systems and problems that can be used for a hands-on approach to the subject, ultimately aiming to show that any problem should be viewed as being suitable to be attacked from a variety of angles, and sometimes by a combination of techniques.

**Learning Outcomes**: After completing PLI31/INF31 a student will be able:

- to streamline problem solving by selecting a suitable representation for the state space and by applying fundamental search algorithms (exhaustive search, heuristic search)
- to represent knowledge in predicate logic and to convert it to a form that can be submitted to reasoning via resolution
- to solve a search/optimization problem using genetic algorithms, by suitably selecting a representation and some genetic operators
