MICRORAM: A simulation model of a colony of bacteria evolving inside an artificial world.
MICRORAM is a simulation model in which a colony of bacteria evolves inside an artificial world. The population or bacterial colony is modeled based on an agent algorithm, exploring the role of conjugation in a genetic algorithm. The ‘bacterial’ agents -

Can a bacterial colony design a radio receiver? A genetic algorithm based on a bacterial conjugation genetic operator
At present, all methods in Evolutionary Computation are bioinspired by the fundamental principles of neo-
We introduced a biologically inspired conjugation operator simulating the genetic mechanism exhibited by bacterial colonies . The efficiency of the bacterial conjugation operator is illustrated designing with a genetic algorithm based on this operator an AM radio receiver, optimizing the main features of the electronic components of the AM radio circuit, as well as those of the radio enclosure.
Virus transduction is one of the key mechanisms of horizontal gene propagation in microorganisms (e.g. bacteria). In the present paper , we model and simulate a transduction operator, exploring the possible role and usefulness of transduction in a genetic algorithm. The genetic algorithm including transduction has been named PETRI (abbreviation of Promoting Evolution Through Reiterated Infection). Our results  showed how PETRI approaches higher fitness values as transduction probability comes close to 100%. The conclusion is that transduction improves the performance of a genetic algorithm, assuming a population divided among several sub-
Cheating for 'problem solving': A genetic algorithm with social interactions
We proposed a variation of the standard genetic algorithm that incorporates social interaction between the individuals in the population . The model was developed in 2008 at the University of Nottingham in collaboration with Uwe Aickelin and Gabriela Ochoa. Our goal was to understand the evolutionary role of social systems and its possible application as a non-
From classical to quantum genetic algorithms
During the last few years we have worked on issues related to Genetic Algorithms  and the Dawkins' biomorphs model . Also, during the year 2015 we started in the University of Stirling (Scotland, UK) the research in quantum genetic algorithms  (see Quantum biology).
