Martinez, K. Morita, & T. Worsch (Eds.), Automata 2008: Theory and Applications of Cellular Automata (356-367). Frome: Luniver PressPatterns, originating from different sources of perturbations, propagating in a precipitating chemical medium do usually compete for the space. They sub-divide the medium onto the regions unique for an initial configuration of disturbances. This sub-... Read More about Computation by competing patterns: life rule B2/S2345678.
Evolving localizations in reaction-diffusion cellular automata (2008)

International Journal of Modern Physics C, 19(04), 557-567. https://doi.org/10.1142/S0129183108012376We consider hexagonal cellular automata with immediate cell neighbourhood and three cell-states. Every cell calculates its next state depending on the integral representation of states in its neighbourhood, i.e., how many neighbours are in each one s...

Artificial Life, 14(2), 203-222. https://doi.org/10.1162/artl.2008.14.2.203We propose that the behavior of nonlinear media can be controlled automatically through evolutionary learning. By extension, forms of unconventional computing (viz., massively parallel nonlinear computers) can be realized by such an approach. In this...

International Journal of Modern Physics C, 19(02), 351-367. https://doi.org/10.1142/S012918310801211XThis paper considers an extension to the standard framework of cellular automata which implements memory capabilities by featuring cells by elementary rules of its last three states. A study is made of the potential value of elementary cellular autom... Read More about Random number generation by cellular automata with memory.
