Explanations are a technique for reasoning about constraint propagation, which have been applied in many learning, backjumping and user-interaction algorithms for constraint progra...
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 ...
: This paper proposes a constraint programming based approach to handle ontologies consistency, and more precisely user-defined consistencies. In practice, ontologies consistency i...
Constraint programming often involves global constraints, for which various custom filtering algorithms have been published. This work presents a semi-automatic generation of CHR s...
This article deals with the resolution of over-constrained problems using constraint programming, which often imposes to add to the constraint network new side constraints. These ...
