Download or read book Color Sudoku written by Philip Riley and published by Sterling Publishing Company. This book was released on 2007-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sudoku fans will welcome this bright new twist to the popular puzzles! Every one of these ingenious creations--from "Bold X" to "Rainbow Up"--makes colors and patterns part of the solving fun. And although each puzzle maintains the normal 9x9 grid and follows the basic rules of the game, every style adds an additional restriction to intensify the challenge. In "Worms," for example, swirly, squirmy shapes fill the grids; the numbers increase as you work your way from head to tail. "Even/Odd" features squares in two colors, depending on whether the number to fill it is even or odd. And in "Positional Board," no two of the red squares can be the same number. They're all lots of fun!

Download or read book Pattern Based Constraint Satisfaction and Logic Puzzles Second Edition written by Denis Berthier and published by . This book was released on 2015-07-11 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: ""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.

Download or read book Kendoku Extreme written by David Levy and published by Seven Footer Press. This book was released on 2010-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hot on the heels of the first two volumes,Kendoku: Extremeshows that when it comes to mind-bendingly difficult logic/arithmetic puzzles, too much is never enough! Combining the logic of Sudoku with the math play of KenKen, Kendoku’s rules are simple enough: The puzzles, either 6x6 or 9x9, look like Killer Sudoku games but in addition to numbers, players also must contend with math operators (+ - × ÷) within "fences” on the puzzle. The total at the top left of the fenced area is arrived at by using the operator on all the numbers within the fenced area. The solution is a valid Sudoku solution. But unlike in Killer Sudoku, in Kendoku numbers are allowed to be repeated within a fenced area as long as the result doesn't break the rules for a valid Sudoku.

Download or read book The Hidden Logic of Sudoku written by Denis Berthier and published by Lulu.com. This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "Hidden Logic of Sudoku" provides the first systematic perspective of the logical symmetries of the popular game. These are fully exploited to define new graphical representations, new kinds of resolution rules and a precedence ordering of the rules consistent with their logical complexity. The set of rules defined in the book is illustrated with a hundred of puzzles together with their full resolution paths. It suffices to solve almost any puzzle without making guesses or assuming the uniqueness of a solution. It has been fed into an Artificial Intelligence (AI) engine and a large database of puzzles has been processed, leading to a precise evaluation of the efficiency of each rule. The book is intended for both advanced Sudoku players (who will discover many new facets of the game and a new, systematic approach to the resolution rules) and for teachers or students of Logic or AI (who will appreciate the strict logical foundations).
