The scope of this book is moving a few steps toward the systematization of the path that goes from the invention to the implementation and testing of a global optimization algorithm. Some of the contributors to the book are famous and some are less well-known, but all are experts in the discipline of actually getting global optimization to work. Thus, the papers in this book address the following topics: - Descriptions of new implementations of general-purpose or problem-specific global optimization algorithms - New algorithms in global optimization (some with numerical results and a discussion of the implementation) - Surveys discussing existing software packages.
