Reviews

From the reviews: "The book explores the knapsack problem and its variants in 15 chapters … . On the whole, the authors present a rich amount of material, much of which belongs to the most recent advancement in the subject … . This self-contained monograph is a valuable addition to the existing literature on knapsack problems. It will certainly make an excellent reference for researchers in combinatorial optimization. … In this regard, the libraries in this field-should have a copy of this book on their shelves." (J Xue, Journal of the Operational Research Society, Vol. 56 (11), 2005) "This book provides a comprehensive overview of the methods for solving KP, its variants and generalizations. … By presenting a range of algorithmic techniques, this book is also a suitable tool for studying modern algorithms. … With its more than 500 references and its author and subject indexes, this book will be a valuable tool for many researchers in combinatorial optimization." (Peter Butkovic, Mathematical Reviews, 2006 d) "This book presents a large number of new results for knapsack problems, especially related to exact and approximate (heuristic) algorithms. Moreover, many modifications and extensions of the knapsack problem are treated. To do this, the authors found and consequently used a close connection between manifold contents and a clear, stimulating presentation. … With an introduction into NP-completeness of knapsack problems a monograph ends, which spans the range from a comprehensive introduction to the most recent and advanced results very nicely." (Jürgen Köhler, OR Spectrum, Issue 27, 2005) "The book starts with a basic introduction to the knapsack problem … . It proceeds with a discussion about the basic techniques available for the solution to this problem, which makes it useful reading for undergraduate students of computer science, mathematics and economics. … In conclusion, it could be said thatthe book is a valuable source for students, but also for researchers interested in this problem."
