  solve difficult sudoku problems: 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.

  solve difficult sudoku problems: Tools and Applications with Artificial Intelligence Constantinos Koutsojannis, Spiros Sirmakessis, 2008-10-17 In recent years, the use of Artificial Intelligence (AI) techniques has been greatly increased. The term “intelligence” seems to be a “must” in a large number of European and International project calls. AI Techniques have been used in almost any domain. Application-oriented systems usually incorporate some kind of “intelligence” by using techniques stemming from intelligent search, knowledge representation, machine learning, knowledge discovery, intelligent agents, computational intelligence etc. The Workshop on “Applications with Artificial Intelligence” seeks for quality papers on computer applications that incorporate some kind of AI technique. The objective of the workshop was to bring together scientists, engineers and practitioners, who work on designing or developing applications that use intelligent techniques or work on intelligent techniques and apply them to application domains (like medicine, biology, education etc), to present and discuss their research works and exchange ideas in this book.

  solve difficult sudoku problems: 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).
  solve difficult sudoku problems: Research and Development in Intelligent Systems XXIV Max Bramer, Frans Coenen, Miltos Petridis, 2007-12-03 An agent in a multi-agent system (MAS) has to generate plans for its individual goal, but these plans may con?ict with those that are already being scheduled or executed by other agents. It must also be able to complete its planning and resolution of these con?icts within a reasonable time to have an acceptable quality plan. Although we adopt hierarchical planning (HP, for example, see [7, 12]) using the decision-theoretic planning (DTP) approach [6] for ef?cient planning, it is not trivial to apply HPO to MAS. In HP, appropriate (abstract) plans are selected level by level to maximize the utility U (p), where where p is the expected ?nal plan comprising a sequence of primitive actions. However, in the MAS context, con?icts between agents affect the ef?ciency and quality of resulting plans. When a con?ict is found at lower levels, an additional sophisticated process for avoiding it (con?ict resolution) must be invoked and some extra actions (such as waiting for synchronization and detouring) may have to be added to the plan. The con?ict resolution process may become costly or fail. Even a single con?ict, if it is dif?cult to resolve, will result in a plan with considerably lower quality than it otherwise would have. As a result, in multi-agent systems, the second- or third-best plans may result in better overall performance.

  solve difficult sudoku problems: A to Z of Sudoku Narendra Jussien, 2007-01-29 Sudoku is a logic puzzle that has become a worldwide phenomenon in the last few years: but where has it come from? How does it work? And what is the science behind sudoku – what are the rules for generating and solving grids? Answers to all of these questions can be found in the A-Z of Sudoku. As its title suggests, this book provides a “one stop shop” on sudoku, covering the history of the puzzle, its development and growth in the world’s media, before moving on to the mathematics of sudoku and various techniques that can be used to solve grids by hand. Next, the essentials of software development relating to sudoku are presented along with the recent branch of computer science devoted to solving such problems: constraint programming, showing how the principle behind solving sudoku grids can be used in other contexts. Finally, the book concludes with a large number of grids ranging in difficulty from “very easy” to “expert” which the reader can use to apply the techniques they have acquired from the book in a practical context. Those interested in finding out more about the theory behind sudoku, its origins, it applications in other fields and (of course) how to improve their ability to solve it will find this book a must-read.

  solve difficult sudoku problems: 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.

  solve difficult sudoku problems: No Rules Rules Reed Hastings, Erin Meyer, 2020-09-08 The New York Times bestseller Shortlisted for the 2020 Financial Times & McKinsey Business Book of the Year Netflix cofounder Reed Hastings reveals for the first time the unorthodox culture behind one of the world's most innovative, imaginative, and successful companies There has never before been a company like Netflix. It has led nothing short of a revolution in the entertainment industries, generating billions of dollars in annual revenue while capturing the imaginations of hundreds of millions of people in over 190 countries. But to reach these great heights, Netflix, which launched in 1998 as an online DVD rental service, has had to reinvent itself over and over again. This type of unprecedented flexibility would have been impossible without the counterintuitive and radical management principles that cofounder Reed Hastings established from the very beginning. Hastings rejected the conventional wisdom under which other companies operate and defied tradition to instead build a culture focused on freedom and responsibility, one that has allowed Netflix to adapt and innovate as the needs of its members and the world have simultaneously transformed. Hastings set new standards, valuing people over process, emphasizing innovation over efficiency, and giving employees context, not controls. At Netflix, there are no vacation or expense policies. At Netflix, adequate performance gets a generous severance, and hard work is irrel­evant. At Netflix, you don’t try to please your boss, you give candid feedback instead. At Netflix, employees don’t need approval, and the company pays top of market. When Hastings and his team first devised these unorthodox principles, the implications were unknown and untested. But in just a short period, their methods led to unparalleled speed and boldness, as Netflix quickly became one of the most loved brands in the world. Here for the first time, Hastings and Erin Meyer, bestselling author of The Culture Map and one of the world’s most influential business thinkers, dive deep into the controversial ideologies at the heart of the Netflix psyche, which have generated results that are the envy of the business world. Drawing on hundreds of interviews with current and past Netflix employees from around the globe and never-before-told stories of trial and error from Hastings’s own career, No Rules Rules is the fascinating and untold account of the philosophy behind one of the world’s most innovative, imaginative, and successful companies.
  solve difficult sudoku problems: Massively Parallel Evolutionary Computation on GPGPUs Shigeyoshi Tsutsui, Pierre Collet, 2013-12-05 Evolutionary algorithms (EAs) are metaheuristics that learn from natural collective behavior and are applied to solve optimization problems in domains such as scheduling, engineering, bioinformatics, and finance. Such applications demand acceptable solutions with high-speed execution using finite computational resources. Therefore, there have been many attempts to develop platforms for running parallel EAs using multicore machines, massively parallel cluster machines, or grid computing environments. Recent advances in general-purpose computing on graphics processing units (GPGPU) have opened up this possibility for parallel EAs, and this is the first book dedicated to this exciting development. The three chapters of Part I are tutorials, representing a comprehensive introduction to the approach, explaining the characteristics of the hardware used, and presenting a representative project to develop a platform for automatic parallelization of evolutionary computing (EC) on GPGPUs. The 10 chapters in Part II focus on how to consider key EC approaches in the light of this advanced computational technique, in particular addressing generic local search, tabu search, genetic algorithms, differential evolution, swarm optimization, ant colony optimization, systolic genetic search, genetic programming, and multiobjective optimization. The 6 chapters in Part III present successful results from real-world problems in data mining, bioinformatics, drug discovery, crystallography, artificial chemistries, and sudoku. Although the parallelism of EAs is suited to the single-instruction multiple-data (SIMD)-based GPU, there are many issues to be resolved in design and implementation, and a key feature of the contributions is the practical engineering advice offered. This book will be of value to researchers, practitioners, and graduate students in the areas of evolutionary computation and scientific computing.
  solve difficult sudoku problems: An Anthropology of Puzzles Marcel Danesi, 2018-12-13 An Anthropology of Puzzles argues that the human brain is a puzzling organ which allows humans to literally solve their own problems of existence through puzzle format. Noting the presence of puzzles everywhere in everyday life, Marcel Danesi looks at puzzles in society since the dawn of history, showing how their presence has guided large sections of human history, from discoveries in mathematics to disquisitions in philosophy. Danesi examines the cognitive processes that are involved in puzzle making and solving, and connects them to the actual physical manifestations of classic puzzles. Building on a concept of puzzles as based on Jungian archetypes, such as the river crossing image, the path metaphor, and the journey, Danesi suggests this could be one way to understand the public fascination with puzzles. As well as drawing on underlying mental archetypes, the act of solving puzzles also provides an outlet to move beyond biological evolution, and Danesi shows that puzzles could be the product of the same basic neural mechanism that produces language and culture. Finally, Danesi explores how understanding puzzles can be a new way of understanding our human culture.
  solve difficult sudoku problems: MODUS FORTIS Sudoku Logic, Sudoku Reason Sudoku Sam, 2024-08-09 Modus Fortis represents a Khunian shift in Sudoku strategy. Using just four basic tactics that give rise to just two molecular structures--Doubles and Pairs--that evolve into just two Families of complex structures (Exclusive Sets and Forbidden Sets) is all that is needed to solve every Sudoku. But just as E = mc2 is easy to visualize, there is a bit more to understanding the equation. The logical principle that drives the Solution Process is the Exclusive Disjunction: the Modus Fortis. This, combined with the Pairing Principle, guides the Sudoku-ka through the process of constructing a Solution from emerging Sets of Digits, identifiable as structural patterns. 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.
  solve difficult sudoku problems: Optimization Modelling Using R Timothy R. Anderson, 2022-07-05 This book covers using R for doing optimization, a key area of operations research, which has been applied to virtually every industry. The focus is on linear and mixed integer optimization. It uses an algebraic modeling approach for creating formulations that pairs naturally with an algebraic implementation in R. With the rapid rise of interest in data analytics, a data analytics platform is key. Working technology and business professionals need an awareness of the tools and language of data analysis. R reduces the barrier to entry for people to start using data analytics tools. Philosophically, the book emphasizes creating formulations before going into implementation. Algebraic representation allows for clear understanding and generalization of large applications, and writing formulations is necessary to explain and convey the modeling decisions made. Appendix A introduces R. Mathematics is used at the level of subscripts and summations Refreshers are provided in Appendix B. This book: • Provides and explains code so examples are relatively clear and self-contained. • Emphasizes creating algebraic formulations before implementing. • Focuses on application rather than algorithmic details. • Embodies the philosophy of reproducible research. • Uses open-source tools to ensure access to powerful optimization tools. • Promotes open-source: all materials are available on the author’s github repository. • Demonstrates common debugging practices with a troubleshooting emphasis specific to optimization modeling using R. • Provides code readers can adapt to their own applications . This book can be used for graduate and undergraduate courses for students without a background in optimization and with varying mathematical backgrounds.
  solve difficult sudoku problems: Language and Mathematics Marcel Danesi, 2016-06-06 This book explores the many disciplinary and theoretical links between language, linguistics, and mathematics. It examines trends in linguistics, such as structuralism, conceptual metaphor theory, and other relevant theories, to show that language and mathematics have a similar structure, but differential functions, even though one without the other would not exist.
