. The concept itself is simple enough. Actually reaching this conceptual point took a while. Complex mathematical models have been, and are, common; deceivingly simple models only have their roots in the late forties, and took the advent of the microcomputer to really get up to speed.

Overview


The aim is to construct parallel simulations consisting of computational devices, referred to as agents, with given properties, in order to model the target phenomena. The subject is the process of emergence

 from the lower (micro) level of a social system to the higher (or macro) level.

The history of agent-based modeling can be traced back to Von Neumann machines, the concept of a machine capable of reproduction. The device he proposed would follow precisely detailed instructions to fashion a copy of itself. The concept was then extended by von Neumann's friend Stanislaw Ulam, also a mathematician, who suggested that the machine be built on paper, as a collection of cells on a grid. The idea intrigued von Neumann, who drew it up, thus creating the first of the devices later termed cellular automata
Cellular automaton
A cellular automaton is a discrete model studied in computability theory, mathematics, physics, complexity science, theoretical biology and microstructure modeling. It consists of a regular grid of cells, each in one of a finite number of states, such as "On" and "Off"...
