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.

Sudoku is a wildly popular puzzle game. Sudoku puzzles are 9x9 grids, and each square in the grid consists of a 3x3 subgrid called a region. Your goal is to fill in the squares so that each column, row, and region contains the numbers 1 through 9 exactly once. And some squares already contain numbers or symbols, which lend clues toward the solution. Programming Sudoku provides you with great approaches to building and solving Sudoku and other similar puzzles. Using ingenious artificial intelligence and game theory techniques, you'll learn how to get a computer to solve these puzzles for you. This is a fun, intriguing read, whether you're a novice or advanced programmer. It acknowledges the .NET platform as a base, but you'll find this book interesting whatever your programming background. The core techniques in the book enable you to solve Sudoku on any programming platform.

Sudoku Programming with C teaches you how to write computer programs to solve and generate Sudoku puzzles. This is a practical book that will provide you with everything you need to write your own books of Sudoku Classic and Samurai puzzles. But be warned: after reading it, you'll discover that the puzzles in your local paper are not so challenging after all! We like Sudokus because they test our capacity to recognize and interpret patterns. But how are the clues generated? Where do those quasi-symmetrical configurations come from? When the author explored the Web to find out, he discovered that there were many sites that explained how to solve Sudokus, but none that told him how create them. He also saw many sites and apps to play Sudoku, but, perhaps not surprising, no indication of how they worked. So, he had to develop his own applications in order to find out. And, from the very start, he decided that he would publish the code for anyone else to use and perhaps tinker with, but the author wrote it in such a way that also lets readers with limited knowledge of programming techniques understand it. In fact, you could decide to start generating thousands of puzzles almost immediately, and go through the explanations of algorithms and techniques later, a bit at a time. The author chose to write the application in ‘plain old C’ because he wanted to make the code accessible to as many people as possible. In this book, you will find an explanation of all solving strategies, and the code to implement them. Writing the Solver application was more difficult than writing the Generator, because it required designing and implementing each strategy separately. However, the author wanted to include a solving program capable of listing the strategies necessary to solve any particular puzzle. He also wanted to check whether a puzzle was solvable analytically, without any guessing. This book includes the full listings of both the Generator and the Solver, and explanations of all C modules, with walk-throughs and examples.

The Annotated Sudoku uses a simple marking system called Sudoglyphics, which builds a path for beginning, experienced, and expert solvers to discover the joy of successfully taking on even the most difficult puzzles and completing them faster than they might have thought possible. The method specifically records and updates the status of every possible answer that remains after an analysis has been performed. The constant marking keeps the solver more engaged between answers. Meanwhile, the accumulation of these marks build visual patterns that otherwise must be created and juggled in memory until they are needed to restart solving where others will most likely get stuck. Included in the book is a step-by-step illustrated explanation for solving a complete, expert-level puzzle using the simple tools and strategies discussed. Regardless of your experience, you can learn to take on the sudoku challenge at the highest level and perform faster without needlessly taxing your memory or backtracking.
