In this paper we introduce a new generic selection method for Genetic Algorithms. The main difference of this selection principle in contrast to conventional selection models is given by the fact that it considers not only the fitness of an individual compared to the fitness of the total population in order to determine the possibility of being selected. Additionally, in a second selection step...

Fixation prevents the associations that are bridges to new designs. The inability to see alternative solutions, or how known solutions can map onto current problems, is a particularly acute problem in the design of software-intensive systems. Here, we study two related ways of liberating fixated thinking: abstracting and re-representing. We find that both techniques can help designers generate ...

A pilot programme promoting fitness and exercise was launched through the local media in the Bournemouth area. The aim was to study the feasibility and effectiveness of a fitness testing programme as a trigger to increase exercise participation. Three hundred and eighty adult volunteers (male and female, all ages) undertook a sub-maximal fitness test and were given advice on exercise and diet b...

Evolution by natural selection may include both frequency and density-dependence. Frequency-dependent selection is a kind of hermeneutic circle. As a literary term (and a school of philosophy), a hermeneutic circle describes how each word of a sentence or paragraph simultaneously draws its meaning from its context (the other words) and contributes towards the context. Frequency dependence is li...

In this paper we propose an extension of classification algorithm based on ant colony algorithms to handle continuous valued attributes using the concepts of fuzzy logic. The ant colony algorithms transform continuous attributes into nominal attributes by creating clenched discrete intervals. This may lead to false predictions of the target attribute, especially if the attribute value history i...

In this paper, a model for understanding the effects of selection using systems-level computational approaches is introduced. A number of concepts and principles essential for understanding the motivation for constructing the model will be introduced first. This will be followed by a description of parameters, measurements, and graphical representations used in the model. Four possible outcomes...

An oil tube defect detection method based on self-adaptive genetic fuzzy neural network is proposed, and it got the original information by multi-group vortex sensors and leakage magnetic sensors. We made multi-scale wavelet transform and frequency analysis to multi-channels original data and extracted multiattribute parameters from time domain and frequency domain, and then we selected the key...
