Deterministic and Non-deterministic Emergence

Click on setup single cell to begin with a single cell in the middle on; setup random picks a random set of cells to begin as on, the number of which is determined by the density slider.

The rule slider selects one of the 256 possible rule sets (see Deterministic Emergence). A cell can be "on" (white) or "off" (black). Each rule sets specifies the resulting on or off state given the states of a cell and it's two neighbors. These switches are set automatically according to the rule slider, but can also be set individually.

Running the model

Click on step to run a single iteration or go to run the model continuously. The auto-continue? switch determines whether or not the cellular automata continues from the top once it reaches the bottom of the screen.

states explored keeps track of how many of the possible states (512 in this model) have occured at least once. % explored displays this as a percentage.
