Graph Properties Based Filtering
Abstract. This report presents a generic filtering scheme, based on the graph description of global constraints. This description is defined by a network of binary constraints and ...

The Parameterized Complexity of Global Constraints
We argue that parameterized complexity is a useful tool with which to study global constraints. In particular, we show that many global constraints which are intractable to propag...

Unary Resource Constraint with Optional Activities
Scheduling is one of the most successful application areas of constraint programming mainly thanks to special global constraints designed to model resource restrictions. Among thes...

Linear Formulation of Constraint Programming Models and Hybrid Solvers
Constraint programming offers a variety of modeling objects such as logical and global constraints, that lead to concise and clear models for expressing combinatorial optimization...

Cost Evaluation of Soft Global Constraints
This paper shows that existing definitions of costs associated with soft global constraints are not sufficient to deal with all the usual global constraints. We propose more expre...

Global Constraints for Integer and Set Value Precedence
The paper introduces value precedence on integer and set sequences. A useful application of the notion is in breaking symmetries of indistinguishable values, an important class of ...

The Tractability of Global Constraints
Abstract. Constraint propagation is one of the techniques central to the success of constraint programming. Fast algorithms are used to prune the search space either before or duri...

Disjoint, Partition and Intersection Constraints for Set and Multiset Variables
We have started a systematic study of global constraints on set and multiset variables. We consider here disjoint, partition, and intersection constraints in conjunction with cardi...

A mobile agent approach for global database constraint checking
Integrity constraints are valuable tools for enforcing consistency of data in a database. Global integrity constraints ensure integrity and consistency of data spanning multiple d...

Compositional Derivation of Symmetries for Constraint Satisfaction
This paper reconsiders the problems of discovering symmetries in constraint satisfaction problems (CSPs). It proposes a compositional approach which derives symmetries of the appli...
