Course Objective

The course provides a broad overview of concepts and methods used in
the field of complex adaptive systems. Methods of dynamical systems
and statistical physics provide the tools for formally describing and
analysing these systems. The collective dynamics are illustrated by
means of computer simulations, mainly using multi-agent approaches

Learning Outcomes of the Course Unit

1   Be aware of simple systems that exhibit nonlinear and complex behaviour
2   Be able to analyse nonlinear systems and find stationary points
3   Posses the ability to analyse bifurcation diagrams and identify key features on these diagrams
4   Understand the origin of deterministic chaos and explain key features relating to chaos
5   Be able to demonstrate an understanding of the algorithms described in the course
6   Have demonstrated the ability to implement stable, efficient and numerically correct versions of these algorithms, with source code which is well documented
7   Develop an ability to decide the reliability and usefulness of derived computational results.
8   Appreciate the physical significance of derived computational results.
