Watched Literals for Constraint Propagation in Minion
Efficient constraint propagation is crucial to any constraint solver. We show that watched literals, already a great success in the satisfiability community, can be used to provide...

Static and Dynamic Structural Symmetry Breaking
We reconsider the idea of structural symmetry breaking (SSB) for constraint satisfaction problems (CSPs). We show that the dynamic dominance checks used in symmetry breaking by dom...

Propagation in CSP and SAT
Abstract. Constraint Satisfaction Problems and Propositional Satisfiability, are frameworks widely used to represent and solve combinatorial problems. A concept of primary importan...

The ROOTS Constraint
A wide range of counting and occurrence constraints can be specified with just two global primitives: the Range constraint, which computes the range of values used by a sequence of...

Reasoning by Dominance in Not-Equals Binary Constraint Networks
Dynamic detection and elimination of symmetry in constraints, is in general a hard task, but in Not-Equals binary constraint networks, the symmetry conditions can be simplified. I...

Global Optimization of Probabilistically Constrained Linear Programs
We consider probabilistic constrained linear programs with general distributions for the uncertain parameters. These problems generally involve non-convex feasible sets. We develo...

Inferring Variable Conflicts for Local Search
Abstract. For efficiency reasons, neighbourhoods in local search are often shrunk by only considering moves modifying variables that actually contribute to the overall penalty. The...

The Modelling Language Zinc
We describe the Zinc modelling language. Zinc provides set constraints, user defined types, constrained types, and polymorphic predicates and functions. The last allows Zinc to be ...
