Computer simulation -- tessellation automata.
In the case described, as in a broad spectrum of other studies that can generally be called tessellation automata (von Neumann, 1966: Gardner, 1971), the starting point is a generalization of the physical situation. In fact, one defines a space where spatially distinguishable components interact, thus embodying the concatenation of processes which lead to events among the components.
The model consists of a two-dimensional universe where numerous O elements ("substrate"), and a few * ("catalysts") move randomly in the spaces of a quadratic grid. These elements are endowed with specific properties which determine interactions that may resukt in the production of other elements ("links") with properties of their own and also capable of interactions ("bonding").
