Evolving boolean networks on tunable fitness landscapes (2012)
Journal Article

This paper presents an abstract, tunable model by which to explore aspects of artificial genetic regulatory networks and their design by simulated evolution. The random Boolean network formalism is combined with the NK and $NKCS$ models of fitness la... Read More about Evolving boolean networks on tunable fitness landscapes.

Evolution of plastic learning in spiking networks via memristive connections (2012)
Journal Article

This paper presents a spiking neuroevolutionary system which implements memristors as plastic connections, i.e., whose weights can vary during a trial. The evolutionary design process exploits parameter self-adaptation and variable topologies, allowi... Read More about Evolution of plastic learning in spiking networks via memristive connections.

Creating unorganised machines from memristors (2012)
Presentation / Conference Contribution

On architectures of circuits implemented in simulated Belousov-Zhabotinsky droplets (2012)
Journal Article

When lipid vesicles filled with Belousov-Zhabotinsky (BZ) excitable chemical medium are packed in tight assembles, waves of excitation may travel between the vesicles. When several waves meet in a vesicle some fragments may deflect, others can annihi... Read More about On architectures of circuits implemented in simulated Belousov-Zhabotinsky droplets.

Production system rules as protein complexes from genetic regulatory networks: An initial study (2012)
Journal Article

This short paper introduces a new way by which to design production system rules. An indirect encoding scheme is presented which views such rules as protein complexes produced by the temporal behaviour of an artificial genetic regulatory network. Thi...

Evolution of supershapes for the generation of three-dimensional designs (2012)
Journal Article

This paper explores the evolution of three-dimensional objects with a simple generative encoding, known as the Superformula. Evolving three-dimensional objects has long been of interest in a wide array of disciplines, from engineering (e.g., robotics...

Cartesian genetic programming for memristive logic circuits (2012)
Presentation / Conference Contribution

In this paper memristive logic circuits are evolved using Cartesian Genetic Programming. Graphs comprised of implication logic (IMP) nodes are compared to more ubiquitous NAND circuitry on a number of logic circuit problems and a robotic control task...

Using genetical and cultural search to design unorganised machines (2012)
Journal Article

In 1948 Turing presented a general representation scheme by which to achieve artificial intelligence-his unorganised machines. Significantly, these were a form of discrete dynamical system and yet dynamical representations remain almost unexplored wi...

On natural genetic engineering: structural dynamism in random boolean networks (2012)
Journal Article

This short paper presents an abstract, tunable model of genomic structural change within the cell lifecycle and explores its use with simulated evolution. A well-known Boolean model of genetic regulatory networks is extended to include changes in nod... Read More about On natural genetic engineering: structural dynamism in random boolean networks.

Evolving boolean networks with structural dynamism (2012)
Journal Article

This short article presents an abstract, tunable model of genomic structural change within the cell life cycle and explores its use with simulated evolution. A well-known Boolean model of genetic regulatory networks is extended to include changes in... Read More about Evolving boolean networks with structural dynamism.

A simple computational cell: Coupling boolean gene and protein networks (2012)
Journal Article

This article presents an abstract, tunable model containing two of the principal information-processing features of cells and explores its use with simulated evolution. The random Boolean model of genetic regulatory networks is extended to include a... Read More about A simple computational cell: Coupling boolean gene and protein networks.
