Phenomenology of glider collisions in cellular automaton Rule 54 and associated logical gates (2006)
Journal Article
Rule 54, a two state, three neighbor cellular automaton in Wolfram's systems of nomenclature, is less complex that Rule 110, but nevertheless possess a rich and complex dynamics. We provide a systematic and exhaustive analysis of glider behavior and... Read More about Phenomenology of glider collisions in cellular automaton Rule 54 and associated logical gates.
Computing in spiral rule reaction-diffusion hexagonal cellular automaton (2006)
Journal Article
Phenomenology of reaction-diffusion binary-state cellular automata (2006)
Journal Article
We study a binary-cell-state eight-cell neighborhood two-dimensional cellular automaton model of a quasi-chemical system with a substrate and a reagent. Reactions are represented by semitotalistic transitions rules: every cell switches from state 0 t... Read More about Phenomenology of reaction-diffusion binary-state cellular automata.
Towards predicting spatial complexity: a learning classifier system approach to the identification of cellular automata (2005)
Presentation / Conference Contribution
This paper presents a novel approach to the programming of automata-based simulation and computation using a machine learning technique. The identification of lattice-based automata for real-world applications is cast as a data mining problem. Our ap...

Experimental implementation of collision-based gates in Belousov-Zhabotinsky medium (2005)
Journal Article
We experimentally demonstrate that excitation wave-fragments in a Belousov-Zhabotinsky (BZ) medium with immobilised catalyst can be used to build elementary logical gates and circuits. Following our previous theoretical constructions [Adamatzky A. Co... Read More about Experimental implementation of collision-based gates in Belousov-Zhabotinsky medium.

The interdisciplinary research monograph, which has been peer-reviewed by several international experts assigned by Elsevier, introduces ground breaking original results in formal paradigms, architectures and laboratory implementations of computers b... Read More about Reaction-diffusion computers.
Experimental implementation of mobile robot taxis with onboard Belousov-Zhabotinsky chemical medium (2004)
Journal Article
We discuss the first-ever experimental realization of the onboard excitable chemical controller for stimulus-guided navigation of mobile robots. We demonstrate that the Belousov-Zhabotinsky (BZ) reaction in the form of an onboard thin layer chemical...

Reaction-diffusion navigation robot control: From chemical to VLSI analogic processors (2004)
Journal Article
We introduce a new methodology and experimental implementations for real-time wave-based robot navigation in a complex, dynamically changing environment. The main idea behind the approach is to consider the robot arena as an excitable medium, in whic...

The formation of voronoi diagrams in chemical and physical systems: Experimental findings and theoretical models (2004)
Journal Article
The work discusses the formation of Voronoi diagrams in spatially extended nonlinear systems taking experimental and theoretical results into account. Concerning experimental systems a number of chemical systems used previously as prototype chemical...

Experimental reaction-diffusion chemical processors for robot path planning (2003)
Journal Article
In this paper we discuss the experimental implementation of a chemical reaction-diffusion processor for robot motion planning in terms of finding the shortest collision-free path for a robot moving in an arena with obstacles. These reaction-diffusion... Read More about Experimental reaction-diffusion chemical processors for robot path planning.
Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond (2002)
Journal Article
We exploit the particulars of diffusive wave front interactions in certain types of two-reactant reaction-diffusion medium to construct a laboratory prototype of an XOR gate. In the design, the values of the logic variables are represented by the pre... Read More about Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond.
Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton (2002)
Journal Article
We offer a new approach to computing a shortest collision-free path in a space containing obstacles, using an experimental chemical processor, based on the Belousov-Zhabotinsky (BZ) reaction. The chemical processor was then coupled via optical links... Read More about Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton.
Experimental reaction-diffusion pre-processor for shape recognition (2002)
Journal Article
We have produced an experimental implementation of a massively-parallel reaction-diffusion processor which performs one of the most essential parts of shape recognition - construction of a skeleton. A skeleton is a unique, stable and invariant repres... Read More about Experimental reaction-diffusion pre-processor for shape recognition.
