The Traveling Salesman Problem: 
This book presents the latest findings on one of the most intensely investigated subjects in computational mathematicsthe traveling salesman problem. It sounds simple enough: given a set of cities and the cost of travel between each pair of them, the problem challenges you to find the cheapest route by which to visit all the cities and return home to where you began. Though seemingly modest, this exercise has inspired studies by mathematicians, chemists, and physicists. Teachers use it in the classroom. It has practical applications in genetics, telecommunications, and neuroscience. The authors of this book are the same pioneers who for nearly two decades have led the investigation into the traveling salesman problem. They have derived solutions to almost eightysix thousand cities, yet a general solution to the problem has yet to be discovered. Here they describe the method and computer code they used to solve a broad range of largescale problems, and along the way they demonstrate the interplay of applied mathematics with increasingly powerful computing platforms. They also give the fascinating history of the problemhow it developed, and why it continues to intrigue us. "The authors have done a wonderful job of explaining how they developed new techniques in response to the challenges posed by ever larger instances of the Traveling Salesman Problem."MAA Online "By bringing together the best work from a wide array of researchers, advancing the field where needed, describing their findings in a book, and implementing everything in an extremely wellwritten computer program, the authors show how research in computational combinatorial optimization should be done."Michael Trick, Operations Research Letters "The book is certainly a must for every researcher in practical TSPcomputation."Ulrich Faigle, Mathematical Reviews "It is very well written and clearly structured. Many examples are provided, which help the reader to better understand the presented results. The authors succeed in describing the TSP problem, beginning with its history, and the first approaches, and ending with the state of the art."Stefan Nickel, Zentralblatt MATH "[T]the text read[s] more like a bestseller than a tome of mathematics. . . . The resulting book provides not only a map for understanding TSP computation, but should be the starting point for anyone interested in launching a computational assault on any combinatorial optimization problem."Jan Karel Lenstra, SIAM Review "By bringing together the best work from a wide array of researchers, advancing the field where needed, describing their findings in a book, and implementing everything in an extremely wellwritten computer program, the authors show how research in computational combinatorial optimization should be done."Michael Trick, ScienceDirect "[T]he book provides a comprehensive treatment of the traveling salesman problem and I highly recommend it not only to specialists in the area but to anyone interested in combinatorial optimization."EMS Newsletter Endorsement: Another Princeton book authored or coauthored by William J.
