- Evolving CAs
- ------------
- A program for mutating and evolving 1-d, 5 neighbour CA rules is part
- of the software included with my book "The Global Dynamics of Cellular
- Automata"*.
- As the CA's space-time pattern generates, a key press will flip one
- bit at a random position in the 32 bit rule table (another key flips
- back if the result does not look promising, other keys reset the
- CA's state).
- Using this method of random mutation and artificial selection
- without stopping the CA, I have evolved many examples of "complex
- rules" (with interacting gliders, glider guns etc) supposed to be rare
- in rule space.
