This book provides a general overview and original analysis of new developments and applications in several areas of computational intelligence and information systems. Computational intelligence has become an important tool for engineers to develop and analyze novel techniques to solve problems in basic sciences such as physics, chemistry, biology, engineering, environment, and social sciences. The material contained in this book addresses the foundations and applications of artificial intelligence and decision support systems, complex and biological inspired systems, simulation and evolution of real and artificial life forms, intelligent models and control systems, knowledge and learning technologies, web semantics and ontologies, intelligent tutoring systems, intelligent power systems, self-organized and distributed systems, intelligent manufacturing systems, and affective computing.
