Random Boolean Networks

Series
Cellular Automata
Description
A boolean network is a discrete dynamical system, originally proposed by Stuart Kauffman as a simple model of a genetic regulatory network in a living cell, where genes can switch each other on or off. It consists of a set of boolean variables, each of which is considered a node in a directed graph with links from a fixed number of other nodes, and associated with a boolean function. The functions, links, and initial conditions are all randomly generated: the resulting behavior patterns can be surprisingly regular; an example of "emergent" order. This NetLogo model will help you explore the behavior, orderly or chaotic, of some random boolean networks.
