On the Conversion between Non-Binary and Binary Constraint Satisfaction Problems
It is well known that any non-binary discrete constraint satisfaction problem (CSP) can be translated into an equivalent binary CSP. Two translations are known: the dual graph tra...

Using Auxiliary Variables and Implied Constraints to Model Non-Binary Problems
We perform an extensive theoretical and empirical analysis of the use of auxiliary variables and implied constraints in modelling a class of non-binary constraint satisfaction pro...

A non-binary constraint ordering heuristic for constraint satisfaction problems
Abstract Nowadays many real problems can be modelled as Constraint Satisfaction Problems (CSPs). A search algorithm for constraint programming requires an order in which variables ...

New Lower Bounds of Constraint Violations for Over-Constrained Problems
In recent years, many works have been carried out to solve over-constrained problems, and more speci cally the Maximal Constraint Satisfaction Problem (Max-CSP), where the goal is ...

Constrainedness and Redundancy by Constraint Ordering
Abstract. In constraint satisfaction, a general rule is to tackle the hardest part of a search problem first. In this paper, we introduce a parameter (τ) that measures the constr...
