Encoding Cardinality Constraints using Generalized Selection Networks
Boolean cardinality constraints state that at most (at least, or exactly) k out of n propositional literals can be true. We propose a new class of selection networks that can be used for an efficient encoding of them. Several comparator networks have been proposed recently for encoding cardinality constraints and experiments have proved their efficiency. Those were based mainly on the odd-even ...
متن کاملSmaller Selection Networks for Cardinality Constraints Encoding
Selection comparator networks have been studied for many years. Recently, they have been successfully applied to encode cardinality constraints for SAT-solvers. To decrease the size of generated formula there is a need for constructions of selection networks that can be efficiently generated and produce networks of small sizes for the practical range of their two parameters: n – the number of i...
متن کاملEfficient CNF Encoding of Boolean Cardinality Constraints
In this paper, we address the encoding into CNF clauses of Boolean cardinality constraints that arise in many practical applications. The proposed encoding is efficient with respect to unit propagation, which is implemented in almost all complete CNF satisfiability solvers. We prove the practical efficiency of this encoding on some problems arising in discrete tomography that involve many cardi...
متن کاملIncremental Encoding and Solving of Cardinality Constraints
Traditional SAT-based MaxSAT solvers encode cardinality constraints directly as part of the CNF and solve the entire optimization problem by a sequence of iterative calls of the underlying SAT solver. The main drawback of such approaches is their dependence on the number of soft clauses: The more soft clauses the MaxSAT instance contains, the larger is the CNF part encoding the cardinality cons...
متن کاملImportance of Variables Semantic in CNF Encoding of Cardinality Constraints
In the satisfiability domain, it is well-known that a SAT algorithm may solve a problem instance easily and another instance hardly, whilst these two instances are equivalent CNF encodings of the original problem. Moreover, different algorithms may disagree on which encoding makes the problem easier to solve. In this paper, we focus on the CNF encoding of cardinality constraints, which states t...
