Book Description
Packed with more than a hundred color illustrations and a wide variety of puzzles and brainteasers, Taking Sudoku Seriously uses this popular craze as the starting point for a fun-filled introduction to higher mathematics. How many Sudoku solution squares are there? What shapes other than three-by-three blocks can serve as acceptable Sudoku regions? What is the fewest number of starting clues a sound Sudoku puzzle can have? Does solving Sudoku require mathematics? Jason Rosenhouse and Laura Taalman show that answering these questions opens the door to a wealth of interesting mathematics. Indeed, they show that Sudoku puzzles and their variants are a gateway into mathematical thinking generally. Among many topics, the authors look at the notion of a Latin square--an object of long-standing interest to mathematicians--of which Sudoku squares are a special case; discuss how one finds interesting Sudoku puzzles; explore the connections between Sudoku, graph theory, and polynomials; and consider Sudoku extremes, including puzzles with the maximal number of vacant regions, with the minimal number of starting clues, and numerous others. The book concludes with a gallery of novel Sudoku variations--just pure solving fun! Most of the puzzles are original to this volume, and all solutions to the puzzles appear in the back of the book or in the text itself. A math book and a puzzle book, Taking Sudoku Seriously will change the way readers look at Sudoku and mathematics, serving both as an introduction to mathematics for puzzle fans and as an exploration of the intricacies of Sudoku for mathematics buffs.

Book Description
""Pattern-Based Constraint Satisfaction and Logic Puzzles (Second Edition)"" develops a pure logic, pattern-based perspective of solving the finite Constraint Satisfaction Problem (CSP), with emphasis on finding the ""simplest"" solution. Different ways of reasoning with the constraints are formalised by various families of ""resolution rules,"" each of them carrying its own notion of simplicity. A large part of the book illustrates the power of the approach by applying it to various popular logic puzzles. It provides a unified view of how to model and solve them, even though they involve very different types of constraints: obvious symmetric ones in Sudoku, non-symmetric but transitive ones in Futoshiki, topological and geometric ones in Map colouring, Numbrix and Hidato, non-binary arithmetic ones in Kakuro and both non-binary and non-local ones in Slitherlink. It also shows that the most familiar techniques for these puzzles can be understood as mere application-specific presentations of the general rules.

Book Description
In perhaps his most important literary feat, Norman Mailer fashions an unprecedented portrait of one of the great villains—and enigmas—in United States history. Here is Lee Harvey Oswald—his family background, troubled marriage, controversial journey to Russia, and return to an “America [waiting] for him like an angry relative whose eyes glare in the heat.” Based on KGB and FBI transcripts, government reports, letters and diaries, and Mailer’s own international research, this is an epic account of a man whose cunning, duplicity, and self-invention were both at home in and at odds with the country he forever altered. Praise for Oswald’s Tale “America’s largest mystery has found its greatest interpreter.”—The Washington Post Book World “Mailer is fierce, courageous, and reckless and nearly everything he writes has sections of headlong brilliance. . . . From the American master conjurer of dark and swirling purpose, a moving reflection.”—Robert Stone, The New York Review of Books “A narrative of tremendous energy and panache; the author at the top of his form.”—Christopher Hitchens, Financial Times “The performance of an author relishing the force and reach of his own acuity.”—Martin Amis, The Sunday Times (London) Praise for Norman Mailer “[Norman Mailer] loomed over American letters longer and larger than any other writer of his generation.”—The New York Times “A writer of the greatest and most reckless talent.”—The New Yorker “Mailer is indispensable, an American treasure.”—The Washington Post “A devastatingly alive and original creative mind.”—Life “Mailer is fierce, courageous, and reckless and nearly everything he writes has sections of headlong brilliance.”—The New York Review of Books “The largest mind and imagination [in modern] American literature . . . Unlike just about every American writer since Henry James, Mailer has managed to grow and become richer in wisdom with each new book.”—Chicago Tribune “Mailer is a master of his craft. His language carries you through the story like a leaf on a stream.”—The Cincinnati Post
