Multiconsistency and Robustness with Global Constraints
We propose a natural generalization of arc-consistency, which we call multiconsistency: A value v in the domain of a variable x is kmulticonsistent with respect to a constraint C i...

A Global Constraint for Total Weighted Completion Time
We introduce a novel global constraint for the total weighted completion time of activities on a single unary capacity resource. For propagating the constraint, an O(n4 ) algorithm...

Reformulating Global Grammar Constraints
An attractive mechanism to specify global constraints in rostering and other domains is via formal languages. For instance, the REGULAR and GRAMMAR constraints specify constraints ...

Flow-Based Propagators for the SEQUENCE and Related Global Constraints
We propose new filtering algorithms for the SEQUENCE constraint and some extensions of the SEQUENCE constraint based on network flows. We enforce domain consistency on the SEQUENCE...

A global constraint for total weighted completion time for unary resources
We introduce a novel global constraint for the total weighted completion time of activities on a single unary capacity resource. For propagating the constraint, we propose an O(n4...
