Digraphs: Theory, Algorithms and Applications

The study of directed graphs is presented in this title as a unified survey of the subject. In addition to covering the theoretical aspects, including detailed proofs of many important results, the authors present a number of algorithms and applications. The applications of digraphs and their generalizations include, among other things, developments in the "Travelling Salesman Problem", genetics and network connectivity. More than 700 exercises and 180 figures are covered to help readers to study the topic while open problems and conjectures are intended to inspire further research.
