Complex System Science

A fundamental concept underpinning Complex System Science (CSS) is that local interactions between relatively simple components can lead to considerably more complex nonlocal behaviours.
A fundamental conjecture CSS attempts to study is that these local interactions are the drivers for processes like selforganisation and emergence and, in turn, are responsible for the immense variety of structures, patterns and phenomena we see in Nature.
We ask what it means to carry out CSS by computer modelling and what kind of complexity can we study with this approach. We believe these are important questions, given that so much work in CSS is done with the aid of computer modelling and since much of the development of CSS was made possible by the availability of fast computing.
In particular we discuss a) if and how computer modelling differs when it is applied to a complex rather than to a noncomplex problem, b) what is the role of the modeller in overall complexproblem solving and c) whether common measures of process and model complexity match human perception of the difficulty of solving a 'complex' problem by employing a computer model.
