A cellular automaton is a 4-tuple , where:
- Z is a lattice.
- S is a finite set of cell states or values.
- I is the finite neighborhood.
- f is the transition function.
The lattice is a grid filled with cells, each cell is uniquely identified by its coordinates and value. The cellular automaton evolves via the transition function with respect to the discrete time variable.
Lattice-Gas Cellular Automatons can be used to model physical systems such as fluid and biological systems. Mathematica uses a cellular automatons as a random number generator.
