A sub-excitable Belousov-Zhabotinsky medium exhibits localized travelling excitations (in contrast to an excitable medium exhibiting target or spiral waves). Initially assymetric perturbations give birth to excitation wave-fragments. The shape and ve... Read More about Towards arithmetic circuits in sub-excitable chemical media.

Stochastic automated search methods in cellular automata: The discovery of tens of thousands of glider guns (2010)
Journal Article
Sapin, E., Adamatzky, A., Collet, P., & Bull, L. (2010). Stochastic automated search methods in cellular automata: The discovery of tens of thousands of glider guns. Natural Computing, 9(3), 513-543. https://doi.org/10.1007/s11047-009-9109-0

This paper deals with the spontaneous emergence of glider guns in cellular automata. An evolutionary search for glider guns with different parameters is described and other search techniques are also presented to provide a benchmark. We demonstrate t...
