This book summarizes advances in a number of fundamental areas of optimization with application in engineering design. The selection of the ''best'' or ''optimum'' design has always been a major concern of designers and in recent years interest has grown in applying mathematical optimization techniques to design of large engineering and industrial systems, and in using the computer-aided design packages with optimization capabilities which are now available. Each chapter includes introductory materials so the book can be used as a textbook for graduate level courses on design optimization as well as by practising and research engineers.
