Symbiosis is the phenomenon in which organisms of different species live together in close association. Symbiogenesis is the name given to the process by which symbiotic partners combine and unify. This letter reconsiders previous work using the NKCS... Read More about Artificial symbiogenesis and differing reproduction rates.

Use of a connection-selection scheme in neural XCSF (2010)

XCSF is a modern form of Learning Classifier System (LCS) that has proven successful in a number of problem domains. In this paper we exploit the modular nature of XCSF to include a number of extensions, namely a neural classifier representation, sel...

Many nature-inspired mechanisms have been presented for computational design and optimization. This paper introduces a population-based approach inspired by a form of cultural learning - imitation. Imitation is typically defined as learning through t... Read More about Imitation programming.

Stochastic automated search methods in cellular automata: The discovery of tens of thousands of glider guns (2010)
Journal Article

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...

Index permutations and classes of additive cellular automata rules with isomorphic STD (2010)
Journal Article
Bulitko, V., Voorhees, B., Alonso-Sanz, R., Bull, L., Anghelescu, P., Ionita, S., …Jin, W. (2010). Index permutations and classes of additive cellular automata rules with isomorphic STD. Journal of Cellular Automata, 5(1-2), 1-28

First we consider the question of identifying linear transformations that transform any additive CA rule into an additive CA rule with an isomorphic STD. A general condition is derived. Following on this, we consider a subclass of such transformation... Read More about Index permutations and classes of additive cellular automata rules with isomorphic STD.
