We propose that the behavior of nonlinear media can be controlled dynamically through coevolutionary systems. In this study, a light-sensitive subexcitable Belousov-Zhabotinsky reaction is controlled using a heterogeneous cellular automaton. A checke...

We study a two-dimensional semi-totalistic binary cell-state cellular automaton, which imitates a reversible precipitation in an abstract chemical medium. The systems exhibits a non-trivial growth and nucleation. We demonstrate how basic computationa... Read More about On logical gates in precipitating medium: Cellular automaton model.

Patterns, 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.

Universal computation with limited resources: Belousov-Zhabotinsky and physarum computers (2008)
Journal Article
Adamatzky, A., De Lacy Costello, B., & Shirakawa, T. (2008). Universal computation with limited resources: Belousov-Zhabotinsky and physarum computers. International Journal of Bifurcation and Chaos, 18(08), 2373-2389. https://doi.org/10.1142/S0218127408021750

Using the examples of an excitable chemical system (the Belousov-Zhabotinsky medium) and plasmodium of Physarum polycephalum we show that universal computation in a geometrically unconstrained medium is only possible when resources (excitability or c...
