Complexity in Simple Model Systems

Complex systems consist of large ensembles of elements, which by themselves are relatively simple. However, the elements interact with each other and thereby assemble themselves dynamically into larger patterns of collective behaviour. As a particularly illustrative example one may think of swarms of flying birds, that move more or less coherently along a common path and direction, scatter on certain occasions into sub-groups, whereof some integrate again a brief time later. This way the ensemble of birds is in an ongoing process of reorganization. Comparable synchronization, integration, and segregation processes appear in many complex sytems.

The subsequent three little Java-applets demonstrate noise and order, integration and segregation, in simple model systems.
