This is the Third Edition of “Computational Intelligence: An Introduction”, a successful and easily-accessible text by a recognized leading expert. It provides a very comprehensive introduction to a number of popular Computational Intelligence paradigms. It serves both as an introduction to the first-time Computational Intelligence user, and as a reference to experts in the field. The third edition expands on a number of the paradigms, and adds more recent developments in the fields of Neural Networks, Evolutionary Computation and Swarm Intelligence. In addition, a part is added on Hyper Heuristics and Memetic Computing, plus comprehensive guidelines on empirical analysis procedures. As such, the third edition will also have a hands-on, practical benefit to the reader. The book is intended as a senior graduate/postgraduate text book, and a reference.
