This book applies to the scientific area of electronic design automation (EDA) and addresses the automatic sizing of analog integrated circuits (ICs). Particularly, this book presents an approach to enhance a state-of-the-art layout-aware circuit-level optimizer (GENOM-POF), by embedding statistical knowledge from an automatically generated gradient model into the multi-objective multi-constraint optimization kernel based on the NSGA-II algorithm. The results showed allow the designer to explore the different trade-offs of the solution space, both through the achieved device sizes, or the respective layout solutions.

Two new topology optimization methods are presented and many sampling design methodologies for computer experiments are compared. HIMO combines a sizing optimizer with a metamodeling technique. A sizing optimizer finds feasible and optimal solutions in size (e.g. plate thickness). All performance constraints are handled. Then a metamodel is to fit all optimal solutions and is then used to find the optimal topology design. Only the objective (e.g. weight) is approximated, thus large-scale structural systems can be optimized. HIMO resulted in 18% and 36% weight savings for two real projects. SOTO directly uses a sizing optimizer to optimize topology as well as thickness. The thinner elements are gradually deleted to achieve improved topology. The design problem is then reformulated with much fewer design variables for final sizing optimization. To improve metamodeling in HIMO, 18 experimental design methods are compared. Sample sizes affect accuracy more than design types. Enough samples are needed to achieve low error with one- stage sampling. More uniform sampling does not generally lead to more accurate prediction unless involving extremely non-uniformity.

Differential evolution is a very simple but very powerfulstochastic optimizer. Since its inception, it has proved veryefficient and robust in function optimization and has been appliedto solve problems in many scientific and engineering fields. InDifferential Evolution , Dr. Qing begins with an overview ofoptimization, followed by a state-of-the-art review of differentialevolution, including its fundamentals and up-to-date advances. Hegoes on to explore the relationship between differential evolutionstrategies, intrinsic control parameters, non-intrinsic controlparameters, and problem features through a parametric study.Findings and recommendations on the selection of strategies andintrinsic control parameter values are presented. Lastly, after anintroductory review of reported applications in electrical andelectronic engineering fields, different research groupsdemonstrate how the methods can be applied to such areas as:multicast routing, multisite mapping in grid environments, antennaarrays, analog electric circuit sizing, electricity markets,stochastic tracking in video sequences, and color quantization. * Contains a systematic and comprehensive overview ofdifferential evolution * Reviews the latest differential evolution research * Describes a comprehensive parametric study conducted over alarge test bed * Shows how methods can be practically applied to * mobile communications * grid computing * circuits * image processing * power engineering * Sample applications demonstrated by research groups in theUnited Kingdom, Australia, Italy, Turkey, China, and EasternEurope * Provides access to companion website with code examples fordownload Differential Evolution is ideal for applicationengineers, who can use the methods described to solve specificengineering problems. It is also a valuable reference forpost-graduates and researchers working in evolutionary computation,design optimization and artificial intelligence. Researchers in theoptimization field or engineers and managers involved in operationsresearch will also find the book a helpful introduction to thetopic.
