"Dennis Shasha is the absolute best puzzle writer alive."—David Gelernter, professor of computer science, Yale University In the tradition of Sherlock Holmes, Dr. Ecco is one of the greatest sleuths of our time, a mathematical wizard who uses logic and computer programming to solve crimes, find treasures, and explore space. Join his team, expand the frontiers of your knowledge, and match wits with him on intriguing cases like "The Virus from the Spy" and "The Secrets of Space" and "The Caribou and the Gas." The puzzles collected here require no formal background beyond arithmetic and elementary algebra—just lively curiosity and keen intelligence. With thirty-six illustrated cases organized around eight major mathematical themes (from Combinatorial Geometry and Geography to Ciphers and Secrecy) this book will encourage you to use your mind and your computer in ways you never previously imagined.

Algorithmic puzzles are puzzles involving well-defined procedures for solving problems. This book will provide an enjoyable and accessible introduction to algorithmic puzzles that will develop the reader's algorithmic thinking. The first part of this book is a tutorial on algorithm design strategies and analysis techniques. Algorithm design strategies — exhaustive search, backtracking, divide-and-conquer and a few others — are general approaches to designing step-by-step instructions for solving problems. Analysis techniques are methods for investigating such procedures to answer questions about the ultimate result of the procedure or how many steps are executed before the procedure stops. The discussion is an elementary level, with puzzle examples, and requires neither programming nor mathematics beyond a secondary school level. Thus, the tutorial provides a gentle and entertaining introduction to main ideas in high-level algorithmic problem solving. The second and main part of the book contains 150 puzzles, from centuries-old classics to newcomers often asked during job interviews at computing, engineering, and financial companies. The puzzles are divided into three groups by their difficulty levels. The first fifty puzzles in the Easier Puzzles section require only middle school mathematics. The sixty puzzle of average difficulty and forty harder puzzles require just high school mathematics plus a few topics such as binary numbers and simple recurrences, which are reviewed in the tutorial. All the puzzles are provided with hints, detailed solutions, and brief comments. The comments deal with the puzzle origins and design or analysis techniques used in the solution. The book should be of interest to puzzle lovers, students and teachers of algorithm courses, and persons expecting to be given puzzles during job interviews.

A writer finds himself trapped in an isolated village where anything imagined becomes reality in this wildly inventive contemporary fantasy Hoping to write his book in quiet and seclusion, Horton Smith has returned home to Pilot Knob. Here, in the tiny village where he passed so many carefree childhood years, he is untroubled by the pressures of the big city and can freely answer the call of his muse. Of course, back in the city Horton didn’t have to run from dinosaurs. There were no cartoon hillbillies offering him moonshine, Don Quixote was content to confine himself to the pages of a book, and the Devil himself was not on Horton’s tail. Something very, very unusual is going on in Pilot Knob, and Horton Smith is determined to get to the bottom of it—if his own imagination doesn’t kill him first! In Out of Their Minds, science fiction Grand Master Clifford D. Simak changes gears, treating his readers to a delightfully satiric flight of fancy and fantasy. An award-winning author renowned for his remarkable visions of the future, Simak brings creatures and characters from humankind’s collective imagination to breathtaking life in this fast-moving and unforgettable tale.

Statistics is the activity of inferring results about a population given a sample. Historically, statistics books assume an underlying distribution to the data (typically, the normal distribution) and derive results under that assumption. Unfortunately, in real life, one cannot normally be sure of the underlying distribution. For that reason, this book presents a distribution-independent approach to statistics based on a simple computational counting idea called resampling. This book explains the basic concepts of resampling, then systematically presents the standard statistical measures along with programs (in the language Python) to calculate them using resampling, and finally illustrates the use of the measures and programs in a case study. The text uses junior high school algebra and many examples to explain the concepts. The ideal reader has mastered at least elementary mathematics, likes to think procedurally, and is comfortable with computers.

While many think of algorithms as specific to computer science, at its core algorithmic thinking is defined by the use of analytical logic to solve problems. This logic extends far beyond the realm of computer science and into the wide and entertaining world of puzzles. In Algorithmic Puzzles, Anany and Maria Levitin use many classic brainteasers as well as newer examples from job interviews with major corporations to show readers how to apply analytical thinking to solve puzzles requiring well-defined procedures. The book's unique collection of puzzles is supplemented with carefully developed tutorials on algorithm design strategies and analysis techniques intended to walk the reader step-by-step through the various approaches to algorithmic problem solving. Mastery of these strategies--exhaustive search, backtracking, and divide-and-conquer, among others--will aid the reader in solving not only the puzzles contained in this book, but also others encountered in interviews, puzzle collections, and throughout everyday life. Each of the 150 puzzles contains hints and solutions, along with commentary on the puzzle's origins and solution methods. The only book of its kind, Algorithmic Puzzles houses puzzles for all skill levels. Readers with only middle school mathematics will develop their algorithmic problem-solving skills through puzzles at the elementary level, while seasoned puzzle solvers will enjoy the challenge of thinking through more difficult puzzles.
