metaca

This code creates "meta-" cellular automata spacetime diagrams. That is, the CA's evolve their own rules locally, rather than evolving an abstract state according to one global rule. A MetaCA can be coupled (in one or both directions) with a standard CA.

Previous work with cellular automata feature evolving global rules, including the recent work on PICARD by Theodore Pavlic et al. The current work is the first example that I am aware of that evolves the evolutionary rule locally.

In addition to these 1D examples, our paper (and slides) presented at AISB'15 consider 2D examples. The code for those experiments is in ewenmaclean/2dCA.
