# Cardinality constraints [Using finite domain integers]

## Detailed Description

Note:
Domain consistency on the extended cardinality variables of the Global Cardinality Propagator is only obtained if they are bounds consistent, otherwise the problem of enforcing domain consistency on the cardinality variables is NP-complete as proved by Qumiper et. al. in Improved Algorithms for the Global Cardinality Constraint"
