We are honored and happy to be able to make available this Springer Handbook of
Computational Intelligence, a large and comprehensive account of both the state-ofthe-
art of the research discipline, complemented with some historical remarks, main
challenges, and perspectives of the future. To follow a predominant tradition, we have
divided this Springer Handbook into parts that correspond to main fields that are meant
to constitute the area of computational intelligence, that is, fuzzy sets theory and fuzzy
logic, rough sets, evolutionary computation, neural networks, hybrid approaches and
systems, all of them complemented with a thorough coverage of some foundational
issues, methodologies, tools, and techniques.
We hope that the handbook will serve as an indispensable and useful source of
information for all readers interested in both the theory and various applications of
computational intelligence. The formula of the Springer Handbook as a convenient
single-volume publication project should help the potential readers find a proper tool
or technique for solving their problems just by simply browsing through a clearly
composed and well-indexed contents. The authors of the particular chapters, who are
the best known specialists in their respective fields worldwide, are the best assurance
for the handbook to serve as an excellent and timely reference.
On behalf of the entire computational intelligence community, we wish to express
sincere thanks, first of all, to the Part Editors responsible for the scope, authors, and
composition of the particular parts for their great job to arrange the most appropriate
topics, their coverage, and identify expert authors. Second, we wish to thank all the
authors for their great contributions in the sense of clarity, comprehensiveness, novelty,
vision, and – above all – understanding of the real needs of readers of diverse interests.
All that efforts would not end up with the success without a total and multifaceted
publisher’s dedication and support. We wish to thank very much Dr. Werner Skolaut,
Ms. Constanze Ober, and their collaborators from Springer, Heidelberg, and le-tex
publishingGmbH, Leipzig, respectively, for their extremely effective and efficient handling
of this huge and difficult project.
