This three-volume set deals with several algorithmic approaches for discrete problems as well as with many combinatorial problems. The editors have tried to bring together almost every aspect of the enormous field with emphasis on recent developments. Each chapter is essentially expository in nature, but of scholarly treatment. The work is addressed not only to researchers in discrete optimization, but to all scientists who use combinatorial optimization methods to model and solve problems. Experts in the field as well as nonspecialists should find the material helpful.
