Full Description
Robert Sedgewick, along with Donald Knuth, is one of the very few people with a world-wide reputation for their contributions to the field of computer algorithms. This book is the second of three volumes that survey the most important computer algorithms in use today. Much more than a standard revision, this is a major rewrite. The material is more than five times as long as in the previous edition, which was only available in C and C++. KEY TOPICS: Sedgewick has added a wealth of new exercises, hundreds of new figures, and dozens of new programs. This volume, Part 5, covers graph algorithms, which are pervasive in modern computing appications. Graph algorithms are increasingly critical for a wide range of applications, such as network connectivity, circuit design, scheduling, transaction processing, and resource allocation. In the third edition, many new algorithms are presented, and the explanations of each algorithm are much more detailed than in previous editions. A new text design and detailed, innovative figures, with accompanying commentary, greatly enhance the presentation. Source code for the implementations is available on the Web. The C and C++ versions of this volume have been previously published. Unlike any other book on algorithms, not only will programmers get practical information on using algorithms in their work, they can also be assured that these algorithms rest on the most solid scientific foundations. MARKET: Both professional programmers and computer science students.
