Constraint Handling Rules (CHR) [2,3,4] is a general-purpose programming language based on committed-choice, multi-headed, guarded multiset rewrite rules. As the head of each CHR rule only considers a fixed number of constraints, any form of aggregation over unbounded parts of the constraint store necessarily requires explicit encoding, using auxiliary constraints and rules.
