Emergence 2009: 1D Cellular Automaton Variant I (temporary)

SETUP, STEP, and GO buttons are standard. The spacebar is an action key for GO. INITIAL-STATE allows you to select the initial state of the world from a drop-down menu. The options are:

- SINGLE-SIDE: a single patch on at the left end

- SINGLE-MIDDLE: a single patch on in the middle

- ALTERNATING: every other patch on

- RANDOM: patches on at random, the number of which may be selected with the RANDOM-DENSITY slider, as a percentage of the total number of patches.

- ON-COLOR and OFF-COLOR allow you to select colors to represent the two patch states.

Try setting up the model from different initial states, and with different 'random' densities (including 0% and 100%). See what happens when you change the width or height of the world.

Activity: Try choosing a non-random initial state and allowing it to run for a few thousand ticks. Copy the output from the output box into a text file, reset the model, and run it again. Compare the results from the second run with those from the first- is it deterministic? Now try changing the width of the world and comparing results- do you still get the same values? Does it work with a random setup? What if you change the random setup density between runs?
