Summary
This book provides a unified, insightful, and modern treatment of linear optimization, that is, linear programming,
network flow problems, and discrete optimization. It includes classical topics as well as the state of the art,
in both theory and practice.
Among its special features, the book:
develops the major algorithms and duality theory through a geometric perspective
provides a thorough treatment of the geometry, convergence, and complexity of interior point methods
covers the main methods for network flow problems
contains a detailed treatment of integer programming formulations and algorithms
discusses the art of formulating and solving large scale problems through practical case studies
includes a large number of examples and exercises. Has been developed through extensive classroom use in graduate
courses
