This special issue of Soft Computing contains a selection of extended versions of papers presented during the 12th UK Workshop on Computational Intelligence (UKCI 2012) held at Heriot-Watt University (Edinburgh, UK) on 5–7 September, 2012. UKCI is an annual conference which provides a stimulating forum for the academic community to share ideas on theoretical and practical aspects of computation...

Evolutionary algorithms and computational intelligence are developing sciences that have a strong potential to assist in the generation and evaluation of system and system-of-systems architectures. General techniques used by system engineers are integrated with computational intelligence methods to expand the ability of systems engineers and architects to effectively manage large, imprecise, an...

This paper presents a consolidated view of the computational intelligence used in the natural language steganalysis. In order to understand the human intelligence on natural language, four major computational intelligence methods have been identified. They are bayesian, fuzzy logic, neural network, and genetic algorithm. This paper also presents a measurement tool to measure the natural languag...
