Linear Programming Duality (eBook, PDF)

An Introduction to Oriented Matroids

• Format: PDF

Produktbeschreibung

Linear Programming Duality is one of the cornerstones in combinatorial optimization. The book is written by two authors who have been working in the field of combinatorial optimization for many years. They give an elementary introduction to the theory of oriented matroids. Their approach clarifies the theoretical basis of Linear Programming and simplifies the proofs of standard results. The book contains numerous figures and the authors have included suggestions for further reading after each chapter.
