Most of the real world problems arising in engineering, economics, management, finance, medicine and other domains can be formulated as optimization tasks. These problems are frequently characterized by non-convex, non-differentiable, discontinuous, noisy or dynamic objective functions and constraints which ask for adequate computational methods. The aim of this book is to stimulate the communication between researchers from different fields of optimization and practitioners who need reliable and efficient computational optimization methods. This volume presents a number of papers written by experts in the field of optimization. The papers involve theoretical articles, optimization methodologies, evolutionary optimization procedures and application issues. Anyone interested from the respective fields will find this book extremely useful.
