Set Variables and Local Search
Many combinatorial (optimisation) problems have natural models based on, or including, set variables and set constraints. This was already known to the constraint programming commu...

Inclusion Constraints over Non-empty Sets of Trees
Abstract. We present a new constraint system called INES. Its constraints are conjunctions of inclusions t1 t2 between rst-order terms (without set operators) which are interpreted...

Solution Enumeration for Projected Boolean Search Problems
Many real-world problems require the enumeration of all solutions of combinatorial search problems, even though this is often infeasible in practice. However, not always all parts ...

Solving topological constraints for declarative families of objects
Parametric and feature-based CAD models can be considered to represent families of similar objects. In current modelling systems, however, the semantics of such families are uncle...
