AND/OR Multi-valued Decision Diagrams for Constraint Optimization
We propose a new top down search-based algorithm for compiling AND/OR Multi-Valued Decision Diagrams (AOMDDs), as representations of the optimal set of solutions for constraint opt...

Breaking Symmetry of Interchangeable Variables and Values
Abstract. A common type of symmetry is when both variables and values partition into interchangeable sets. Polynomial methods have been introduced to eliminate all symmetric soluti...

Boosting Probabilistic Choice Operators
Probabilistic Choice Operators (PCOs) are convenient tools to model uncertainty in CP. They are useful to implement randomized algorithms and stochastic processes in the concurrent...

Solution Counting Algorithms for Constraint-Centered Search Heuristics
Constraints have played a central role in cp because they capture key substructures of a problem and efficiently exploit them to boost inference. This paper intends to do the same ...

Encodings of the Sequence Constraint
Abstract. The SEQUENCE constraint is useful in modelling car sequencing, rostering, scheduling and related problems. We introduce half a dozen new encodings of the SEQUENCE constra...

Bound-Consistent Deviation Constraint
Deviation is a recent constraint to balance a set of variables with respect to a given mean. We show that the propagators recently introduced are not bound-consistent when the mean...

Constructive Interval Disjunction
Shaving and constructive disjunction are two main refutation principles used in constraint programming. The shaving principle allows us to compute the singleton arc-consistency (SA...

Min-Domain Ordering for Asynchronous Backtracking
Ordering heuristics are a powerful tool in CSP search algorithms. Among the most successful ordering heuristics are heuristics which enforce a fail first strategy by using the mi...
