Pruning for the cardinality-path constraint family

• This paper presents generic propagation algorithms for the cardinality-path constraint family. This is a restricted form of the cardinality operator that allows stating constraints on sliding sequences of consecutive variables. Taking advantage of these restrictions permits coming up with more efficient algorithms. Moreover the paper shows how to extend these propagation algorithms in order to partially integrate external constraints that have to hold. From an application point of view the cardinality-path constraint allows to express a huge variety of regulation constraints occurring in personnel planning problems.
