Project Title
Space/Time Periodic Perturbations of Cellular Automata
Project
This project examines how cellular automata evolve with perturbations
in the middle of evolution, starting with just elementary cellular
automata (ECA) and expanding to rules with more colors and different
radii. To show the effects of perturbations, one cell will randomly be
changed from 1 to 0 or vice versa, and the evolution will be observed
for change. This will be tested by choosing a random cell in a random
row and choosing a random cell in the same row for every rule.
Another test will be to periodically change a random cell, because
just changing one cell is equivalent to having a different initial
condition.
Favorite Radius 3/2 Rule
Rule chosen: 233
My favorite rule is 233. It's because the evolution reminds me of a
spinning disco ball.
