Tractable Answer-Set Programming with Weight Constraints: Bounded Treewidth Is not Enough
Cardinality constraints or, more generally, weight constraints are well recognized as an important extension of answer-set programming. Clearly, all common algorithmic tasks relat...

Combination of Among and Cardinality Constraints
A cardinality constraint imposes that each value of a set V must be taken a certain number of times by a set of variables X, whereas an among constraint imposes that a certain numb...

Cardinality Networks and Their Applications
We introduce Cardinality Networks, a new CNF encoding of cardinality constraints. It improves upon the previously existing encodings such as the sorting networks of [ES06] in that ...

Evaluation of Cardinality Constraints on SMT-Based Debugging
For formal verification of hardware Satisfiability Modulo Theory (SMT) solvers are increasingly applied. Today’s state-of-the-art SMT solvers use different techniques like ter...

Collections, Cardinalities, and Relations
Abstract. Logics that involve collections (sets, multisets), and cardinality constraints are useful for reasoning about unbounded data structures and concurrent processes. To make ...
