Constraint Automata and the Complexity of Recursive Subtype Entailment
Abstract. We study entailment of structural and nonstructural recursive subtyping constraints. Constraints are formal inequalities between type expressions, interpreted over an ord...

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...

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...
