Applied Integer Programming: Modeling and Solution

Taking an application-oriented approach, Applied Integer Programming addresses the art and science of mathematical modeling related to MIP framework. This book discusses the algorithms and associated practices that enable those models to be solved most efficiently. Organized into three parts, this comprehensive reference eases the learning hurdles in integer programming with suggestions and guidelines for practice on the job for professionals, software developers, and analysts who need to model and solve real-world optimization problems using integer-programming techniques.

Review :
"Thoroughly classroom-tested, Applied integer programming is an excellent book for integer programming courses at the upper-undergraduate and graduate levels." (Mathematical Reviews, 2011) "The book is intended as a textbook for an application oriented course for senior undergraduate or postgraduate students, mainly with an engineering, business school, or applied mathematics background. Each chapter comes with several exercises, solutions of which are provided in an appendix. Many figures illustrate the flow of algorithms and other concepts." ( Zentralblatt MATH , 2010)
