Practical Fault Tolerant 2D Cellular Automata

Steven Janke and Matthew Whitehead


Cellular automata often suffer from a level of brittleness that makes them susceptible to even the smallest unexpected environmental changes. We propose a method of converting CAs into more robust structures called meta-CAs that utilize cell redundancy along with added rules to correct errors and reproduce the functionality of the original CA. We show that the use of these meta-CAs can greatly increase the probability of CAs being intact when executing in an environment where cells fail on each step with a small probability.
