Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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

Book Description
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.

Book Description
"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.

The runaway bestseller with more than five million copies in print! You too can change your life with the priceless wisdom of ten ancient scrolls handed down for thousands of years. “Every sales manager should read The Greatest Salesman in the World. It is a book to keep at the bedside, or on the living room table—a book to dip into as needed, to browse in now and then, to enjoy in small stimulating portions. It is a book for the hours and for the years, a book to turn to over and over again, as to a friend, a book of moral, spiritual and ethical guidance, an unfailing source of comfort and inspiration.”—Lester J. Bradshaw, Jr., Former Dean, Dale Carnegie Institute of Effective Speaking & Human Relations “I have read almost every book that has ever been written on salesmanship, but I think Og Mandino has captured all of them in The Greatest Salesman in the World. No one who follows these principles will ever fail as a salesman, and no one will ever be truly great without them; but, the author has done more than present the principles—he has woven them into the fabric of one of the most fascinating stories I have ever read.”—Paul J. Meyer, President of Success Motivation Institute, Inc. “I was overwhelmed by The Greatest Salesman in the World. It is, without doubt, the greatest and the most touching story I have ever read. It is so good that there are two musts that I would attach to it: First, you must not lay it down until you have finished it; and secondly, every individual who sells anything, and that includes us all, must read it.”—Robert B. Hensley, President, Life Insurance Co. of Kentucky

Book Description
Controversial, confrontational, and driven, Coach Geno Auriemma is a force to be reckoned with -- and the most accomplished male coach in women's basketball today. In his relentless quest for excellence at the University of Connecticut, he has led the Huskies to five national championships. Yet his soul never rests. For Auriemma, life affords only the briefest moments of happiness -- a good round of golf, forty minutes of great basketball, a day at the beach with his family, a nice glass of wine -- while disaster is seemingly always waiting to strike. It's a fatalistic philosophy, a remnant of his hardscrabble early years, but it's an outlook that has driven him to unparalleled success. In this deeply personal memoir, Geno Auriemma reveals for the first time the man behind the legend. He talks candidly about his coaching style, famed for being one of the most demanding in all the sports world. He spills the beans about his stormy dealings with other coaches such as his archrival, Pat Summitt, of the University of Tennessee. And with warmth and a genuine love for his champions, he writes openly about Diana Taurasi, Sue Bird, Nykesha Sales, Rebecca Lobo, Swin Cash, and all of his other UConn stars who have gone on to stellar WNBA careers. You get a courtside seat to all of the action -- including an epilogue on the 2004-05 season, as well as interviews with the team's most celebrated players. A rare look inside the soul of a true competitor, GENO is the story of how one passionate man overcame his own fears to achieve an extraordinary record of success.
