If cellular automata are new to you, you might want to read some of the material referenced by the Links page. CAOS calculates automatically a CA space-time diagram, whenever some value in the user interface changes. Each horizontal line at the display corresponds to a certain point of time. The initial configuration is displayed at the bottom line.
Time flows upwards in vertical direction.
The lattice is implemented as a ring. Active cells that leave at the right edge enter again on the left edge and vice versa. CAOS is written in Java 1.1. CAOS supports general binary, symmetric and totalistic rules. General and symmetric rules are specified as a mapping that maps the different neighborhood configurations to 0 and 1.
