Coevolutionary species adaptation genetic algorithms: A continuing SAGA on coupled fitness landscapes (2005)
Journal Article
Bull, L. (2005). Coevolutionary species adaptation genetic algorithms: A continuing SAGA on coupled fitness landscapes. Lecture Notes in Artificial Intelligence, 3630 LNAI, 322-331. https://doi.org/10.1007/11553090_33

The Species Adaptation Genetic Algorithm (SAGA) was introduced to facilitate the open-ended evolution of artificial systems. The approach enables genotypes to increase in length through appropriate mutation operators and has been successfully exploit...

X-TCS: Accuracy-based learning classifier system robotics (2005)
Journal Article
Studley, M., & Bull, L. (2005). X-TCS: Accuracy-based learning classifier system robotics. https://doi.org/10.1109/CEC.2005.1554954

Although most learning classifier system (LCS) research uses the accuracy-based XCS, it had never been used to control a physical robot before. In comparison to purely evolutionary or purely reinforcement learning approaches, an LCS should be faster... Read More about X-TCS: Accuracy-based learning classifier system robotics.

Coevolutionary species adaptation genetic algorithms: growth and mutation on coupled fitness landscapes (2005)
Presentation / Conference
Bull, L. (2005, September). Coevolutionary species adaptation genetic algorithms: growth and mutation on coupled fitness landscapes. Paper presented at 2005 IEEE Congress on Eolutionary Computation

The species adaptation genetic algorithm (SAGA) was introduced to facilitate the open-ended evolution of artificial systems. The approach enables genotypes to increase in length through appropriate mutation operators. Most recently, this has been und...

Towards predicting spatial complexity: a learning classifier system approach to the identification of cellular automata (2005)
Presentation / Conference
Bull, L., Lawson, I., Adamatzky, A., & de Lacy Costello, B. (2005, September). Towards predicting spatial complexity: a learning classifier system approach to the identification of cellular automata. Paper presented at IEEE Congress on Evolutionary Computation, 2005

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...

Genetic programming with a genetic algorithm for feature construction and selection (2005)
Journal Article
Smith, M. G., & Bull, L. (2005). Genetic programming with a genetic algorithm for feature construction and selection. Genetic Programming and Evolvable Machines, 6(3), 265-281. https://doi.org/10.1007/s10710-005-2988-7

The use of machine learning techniques to automatically analyse data for information is becoming increasingly widespread. In this paper we primarily examine the use of Genetic Programming and a Genetic Algorithm to pre-process data before it is class...

Experimental implementation of collision-based gates in Belousov-Zhabotinsky medium (2005)
Journal Article
De Lacy Costello, B., de Lacy Costello, B., & Adamatzky, A. (2005). Experimental implementation of collision-based gates in Belousov-Zhabotinsky medium. Chaos, Solitons and Fractals, 25(3), 535-544. https://doi.org/10.1016/j.chaos.2004.11.056

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.

Rapid diagnosis of gastro-intestinal infections using faecal odour (2005)
Book Chapter
de Lacy Costello, B., Ewen, R., Garner, K., Probert, C., Ratcliffe, N. M., & Smith, S. (2005). Rapid diagnosis of gastro-intestinal infections using faecal odour. In A. Amann, & D. Smith (Eds.), Breath Analysis For Clinical Diagnosis And Therapeutic Monitoring, 429-436. World Scientific Publishing Company

This book describes how the analysis of the trace gases in exhaled breath can be used for non-invasive clinical diagnosis of disease and for monitoring the effectiveness of therapy. This approach offers an important addition to the diagnostic techniq... Read More about Rapid diagnosis of gastro-intestinal infections using faecal odour.

Procedures for calculating reversible one-dimensional cellular automata (2005)
Journal Article
Martínez, G. J., Vergara, S. V., Mora, J. C. S. T., Mora, J. C., Vergara, S. V., Martinez, G. J., & McIntosh, H. V. (2005). Procedures for calculating reversible one-dimensional cellular automata. Physica D: Nonlinear Phenomena, 202(1-2), 134-141. https://doi.org/10.1016/j.physd.2005.01.018

We describe two algorithms for calculating reversible one-dimensional cellular automata of neighborhood size 2. We explain how this kind of automaton represents all the other cases. Using two basic properties of reversible automata such as uniform mu... Read More about Procedures for calculating reversible one-dimensional cellular automata.
