Volume 1 of 50 17 Clues Sudokus is the first book of a series and contains 50 Sudoku puzzles with only 17 given digits or clues. Scientifically it is proven that 17 clues is the minimum number of given digits to design a standard 9 x 9 Sudoku with a unique solution. All Sudokus in this book have the standard 9 x 9 grid size. Some of these Sudokus (Challenging Sudoku Variations) contain one or more extra groups of nine coherent cells that also have to contain the different digits exactly once. You need these extra group(s) to deduce the unique solution of these Challenging Sudoku Variations, in a regular interaction with the Sudoku logic.Instead of nine different digits some of these Sudokus have nine different letters (WordDokus). The nine different digits form a meaningful English word as extra solution of the WordDoku. Your brain is extra stimulated to solve the Challenging Sudoku Variations such as the X-Doku (with the two diagonals as extra groups), the WinDoku (with four blocks of 3 x 3 cells and extra groups) and the SixGroupsDoku (with nine little groups of three coherent cells forming three horizontal and three vertical groups of nine coherent cells).This book is a must have for all Sudoku enthusiasts that want to break out of the standard Sudokus with at least 24 clues and are eager to be challenged with Sudoku puzzles with extra groups of coherent cells. It will bring you many enjoyable and brain-entertaining hours of Sudoku puzzle fun when solving these exciting 17 clues Sudokus and their variations!

This book treats graph colouring as an algorithmic problem, with a strong emphasis on practical applications. The author describes and analyses some of the best-known algorithms for colouring arbitrary graphs, focusing on whether these heuristics can provide optimal solutions in some cases; how they perform on graphs where the chromatic number is unknown; and whether they can produce better solutions than other algorithms for certain types of graphs, and why. The introductory chapters explain graph colouring, and bounds and constructive algorithms. The author then shows how advanced, modern techniques can be applied to classic real-world operational research problems such as seating plans, sports scheduling, and university timetabling. He includes many examples, suggestions for further reading, and historical notes, and the book is supplemented by a website with an online suite of downloadable code. The book will be of value to researchers, graduate students, and practitioners in the areas of operations research, theoretical computer science, optimization, and computational intelligence. The reader should have elementary knowledge of sets, matrices, and enumerative combinatorics.

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.

""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.
