Hierarchical Classifications in Constraint Satisfaction" starts by recalling the main universal classifications of the instances of a finite binary Constraint Satisfaction Problem, defined in previous books by the same author, as well as their first applications to the Sudoku case. It then introduces a software (SHC) specially developed by François Cordoliani to implement them in the Sudoku case. Finally, it analyses in detail the classificati...

CSP-Rules is a generic pattern-based (or rule-based) solver of finite binary Constraint Satisfaction Problems (CSPs). This software is available on GitHub and it includes fully developed applications to various logic puzzles such as Sudoku, Latin Squares (allowing their Pandiagonal variant), Futoshiki, Kakuro, Numbrix, Hidato, Slitherlink and Map Colouring. CSP-Rules produces not only the solution to a CSP (as all the existing CSP solvers) bu...

This book is the User Manual for CSP-Rules-V2.1, a generic pattern-based (or rule-based) solver of finite binary Constraint Satisfaction Problems (CSPs).

Pattern-Based Constraint Satisfaction and Logic Puzzles (Third 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 a...

Constraint Resolution Theories" introduces a pure logic perspective of the finite Constraint Satisfaction Problem (CSP), with emphasis on finding the "simplest" solution. Based on constructive logic, the resolution paradigm involves resolution rules, i.e. logical formulæ in the condition-action form, where the condition pattern implies the elimination of a candidate (a possible value for a CSP variable). Defining a resolution theory as a set o...

Denis Berthier has spent thirty years observing the night sky from within a city and his practical guide will enable amateur astronomers to observe and photograph stars, planets and other celestial objects from their own town. It is becoming more and more difficult to find an observing site with clear, dark skies away from light and industrial pollution. However, by choosing the right targets to observe, with patience and simple equipment, ama...

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 an...

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 alm...
