The story of one of the greatest unsolved problems in mathematics What is the shortest possible route for a traveling salesman seeking to visit each city on a list exactly once and return to his city of origin? It sounds simple enough, yet the traveling salesman problem is one of the most intensely studied puzzles in applied mathematics—and it has defied solution to this day. In this book, William Cook takes readers on a mathematical excursion, picking up the salesman's trail in the 1800s when Irish mathematician W. R. Hamilton first defined the problem, and venturing to the furthest limits of today’s state-of-the-art attempts to solve it. He also explores its many important applications, from genome sequencing and designing computer processors to arranging music and hunting for planets. In Pursuit of the Traveling Salesman travels to the very threshold of our understanding about the nature of complexity, and challenges you yourself to discover the solution to this captivating mathematical problem.

The Pulitzer Prize-winning tragedy of a salesman’s deferred American dream Ever since it was first performed in 1949, Death of a Salesman has been recognized as a milestone of the American theater. In the person of Willy Loman, the aging, failing salesman who makes his living riding on a smile and a shoeshine, Arthur Miller redefined the tragic hero as a man whose dreams are at once insupportably vast and dangerously insubstantial. He has given us a figure whose name has become a symbol for a kind of majestic grandiosity—and a play that compresses epic extremes of humor and anguish, promise and loss, between the four walls of an American living room. "By common consent, this is one of the finest dramas in the whole range of the American theater." —Brooks Atkinson, The New York Times "So simple, central, and terrible that the run of playwrights would neither care nor dare to attempt it." —Time

The computer science problem whose solution could transform life as we know it The P-NP problem is the most important open problem in computer science, if not all of mathematics. Simply stated, it asks whether every problem whose solution can be quickly checked by computer can also be quickly solved by computer. The Golden Ticket provides a nontechnical introduction to P-NP, its rich history, and its algorithmic implications for everything we do with computers and beyond. Lance Fortnow traces the history and development of P-NP, giving examples from a variety of disciplines, including economics, physics, and biology. He explores problems that capture the full difficulty of the P-NP dilemma, from discovering the shortest route through all the rides at Disney World to finding large groups of friends on Facebook. The Golden Ticket explores what we truly can and cannot achieve computationally, describing the benefits and unexpected challenges of this compelling problem.

This book presents the latest findings on one of the most intensely investigated subjects in computational mathematics--the 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 eighty-six 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 large-scale 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 problem--how it developed, and why it continues to intrigue us.

In her newest well-tuned, witty, and altogether wonderful novel, bestselling author Elinor Lipman dares to ask: Can an upper-middle-class doctor find love with a shady, fast-talking salesman? Meet Alice Thrift, surgical intern in a Boston hospital, high of I.Q. but low in social graces. She doesn’t mean to be acerbic, clinical, or blunt, but where was she the day they taught Bedside Manner 101? Into Alice’s workaholic and wallflower life comes Ray Russo, a slick traveling fudge salesman in search of a nose job and well-heeled companionship, but not necessarily in that order. Is he a conman or a sincere suitor? Good guy or bad? Alice’s parents, roommate, and best friend Sylvie are appalled at her choice of mate. Despite her doubts, Alice finds herself walking down the aisle, not so much won over as worn down. Will their marriage last the honeymoon? Only if Alice’s best instincts can triumph over Ray’s unsavory ways.

"Did you know that every time you pick up the controller to your PlayStation or Xbox, you are entering a game world steeped in mathematics? Power-Up reveals the hidden mathematics in many of today's most popular video games and explains why mathematical learning doesn't just happen in the classroom or from books--you're doing it without even realizing it when you play games on your cell phone. In this lively and entertaining book, Matthew Lane discusses how gamers are engaging with the traveling salesman problem when they play Assassin's Creed, why it is mathematically impossible for Mario to jump through the Mushroom Kingdom in Super Mario Bros., and how The Sims teaches us the mathematical costs of maintaining relationships. He looks at mathematical pursuit problems in classic games like Missile Command and Ms. Pac-Man, and how each time you play Tetris, you're grappling with one of the most famous unsolved problems in all of mathematics and computer science. Along the way, Lane discusses why Family Feud and Pictionary make for ho-hum video games, how realism in video games (or the lack of it) influences learning, what video games can teach us about the mathematics of voting, the mathematics of designing video games, and much more. Power-Up shows how the world of video games is an unexpectedly rich medium for learning about the beautiful mathematical ideas that touch all aspects of our lives--including our virtual ones."--Dust jacket.

In this entertaining and informative book, Walter Friedman chronicles the remarkable metamorphosis of the American salesman from itinerant amateur to trained expert. From the mid-nineteenth century to the eve of World War II, the development of sales management transformed an economy populated by peddlers and canvassers to one driven by professional salesmen and executives. From book agents flogging Ulysses S. Grant's memoirs to John H. Patterson's famous pyramid strategy at National Cash Register to the determined efforts by Ford and Chevrolet to craft surefire sales pitches for their dealers, selling evolved from an art to a science. "Salesmanship" as a term and a concept arose around the turn of the century, paralleling the new science of mass production. Managers assembled professional forces of neat responsible salesmen who were presented as hardworking pillars of society, no longer the butt of endless "traveling salesmen" jokes. People became prospects; their homes became territories. As an NCR representative said, the modern salesman "let the light of reason into dark places." The study of selling itself became an industry, producing academic disciplines devoted to marketing, consumer behavior, and industrial psychology. At Carnegie Mellon's Bureau of Salesmanship Research, Walter Dill Scott studied the characteristics of successful salesmen and ways to motivate consumers to buy. Full of engaging portraits and illuminating insights, Birth of a Salesman is a singular contribution that offers a clear understanding of the transformation of salesmanship in modern America. Reviews of this book: The history Friedman weaves is engrossing and the book hits stride with entertaining chapters on Mark Twain's marketing of the memoirs of Ulysses S. Grant (apparently Twain was as talented a businessman as a writer) and on the shift from the drummer--the middleman between wholesalers and regional shopkeepers--to the department store...In Birth of a Salesman, Friedman has crafted a history of an 'inherently unlikable process' with depth, affection and intelligent analysis. --Carlo Wolff, Boston Globe I very much enjoyed reading this book. It is well written, well argued, and thoroughly researched. Salesmen, Friedman argues, helped distribute the products of America's increasingly bountiful manufacturing industries, invented new forms of managerial hierarchies, investigated the psychology of desire, and were in the vanguard of America's transformation from a producer to a consumer society. He powerfully shows that the rise of modern business practices and the emergence of a particularly American culture of consumption can only be fully understood if we examine the history of selling. --Sven Beckert, author of The Monied Metropolis Walter Friedman's Birth of a Salesman: The Transformation of Selling in America is an important book. The modern industrial economy, created in the United States and Europe between the 1880s and the 1930s, required the integration of large-scale production and marketing. The evolution of mass production is a well-known story, but Friedman is the first to fill in the crucial marketing side of that industrial revolution. --Alfred D. Chandler, Jr., author of The Visible Hand and Scale and Scope With wit and verve, Walter Friedman gives us a cast of memorable characters who turned salesmanship from ballyhoo to behaviorism, from silliness to science. Informed by prodigious research, Birth of a Salesman also clarifies the birth of modern marketing--from an angle that humanizes its subject through wry, ironic, but serious analysis. This is a pioneering work on a subject crucial to American social, cultural, and business history. --Thomas K. McCraw, author of Creating Modern Capitalism
