| sudoku secrets for solving: The Hidden Logic of Sudoku (Second Edition) Denis Berthier, 2007-12 The Hidden Logic of Sudoku provides the first systematic perspective of the logical foundations and of the symmetries of the popular game. These are fully exploited to define new resolution rules, new graphical representations and an ordering of the rules consistent with their complexity. The classical pattern of xy-chains has been extended into a homogeneous set of chain rules that, when added to a few elementary rules, suffices to solve almost any puzzle. These rules are illustrated with a hundred puzzles with their full resolution paths. A large collection of puzzles has been processed by Artificial Intelligence (AI) techniques, leading to a precise evaluation of the efficiency of each rule. This pedagogical book is intended for both Sudoku players (who will discover many new facets of the game and new rules - all set in a uniform conceptual framework based on patterns) and teachers or students of Logic or AI (who will appreciate the strict logical foundations). |

| sudoku secrets for solving: Pattern-Based Constraint Satisfaction and Logic Puzzles (Second Edition) Denis Berthier, 2015-07-11 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. |

| sudoku secrets for solving: I Catch Killers: the Life and Many Deaths of a Homicide Detective Dan Box, Gary Jubelin, 2021-09 Serial killings, child abductions, organised crime hits and domestic murders. This is the memoir of a homicide detective. Here I am: tall and broad, shaved head, had my nose broken three times fighting. Black suit, white shirt, the big city homicide detective. I've led investigations into serial killings, child abductions, organised crime hits and domestic murders. But beneath the suit, I've got an Om symbol in the shape of a Buddha tattooed on my right bicep. It balances the tattoo on my left ribs: Better to die on your feet than live on your knees. That's how I choose to live my life. As a cop, I got paid to catch killers and I learned what doing it can cost you. It cost me marriages and friendships. It cost me my reputation. They tell you not to let a case get personal, but I think it has to. Each one has taken a piece out of me and added a piece, until there's only pieces. I catch killers - it's what I do. It's who I am. Gary Jubelin was one of Australia's most celebrated detectives, leading investigations into the disappearance of preschooler William Tyrrell, the serial killing of three Aboriginal children in Bowraville and the brutal gangland murder of Terry Falconer. During his 34-year career, Detective Chief Inspector Jubelin also ran the crime scene following the Lindt Cafe siege, investigated the death of Caroline Byrne and recovered the body of Matthew Leveson. Jubelin retired from the force in 2019. This is his story. |

| sudoku secrets for solving: SUDOKU PUZZLE SECRETS Mary J. Konta, 2021-05-12 It seems that these days everyone is enjoying the game of Sudoko wherever they are. The Sudoku puzzle is ideal for whenever you have a few spare minutes and want to indulge in a little bit of thinking power. Sudoku, sometimes spelled Su Doku, is a puzzle that originated in Japan. The puzzle is known as a placement puzzle. In the United States Sudoku is sometimes called the Number Place puzzle. Sudoku is easy to learn and understand. The main aim of Sudoku is to enter a number from one to nine into each cell on puzzle grid. The most frequent layout of a Sudoku puzzle is a 9 x 9 grid that is made of subgrids that are 3 x 3. Each of these subgrids is known as a region. Depending on how easy or hard the puzzle is there will be various starting numbers in the cells. These are known as the givens. Every row, column, and region of the Sudoku puzzle can contain only one instance of each number. You complete the puzzle when all of the cells have been filled in with corresponding numbers. To complete the Sudoku puzzle requires a lot of patience as well as the ability to think logically. The basic layout of the Sudoku grid is much like a chess game or crossword puzzles. Sudoku is not just a mathematical or arithmetic type of puzzle. It works just as well if the numbers are substituted with letters or other symbols. However, numbers work best. The great thing about this puzzle is that the basic principle of solving it is really quite simple. All you need to do is fill in the grid in such a way that each row, column, and region contains the numbers one to nine. |
| sudoku secrets for solving: Taking Sudoku Seriously Jason Rosenhouse, Laura Taalman, 2012-01-19 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. |

A concise notation system allows for recording every significant event in the Solution Process, just as in chess. Richly illustrated, this is a readable book for all levels of interest. |
