摘要: A method, apparatus and product for encoding a cardinality constraint in Conjunctive Normal Form (CNF). The method comprising: having a Boolean formula comprising a cardinality constraint, wherein the cardinality constraint relating to a set of Boolean variables, the set of variables consisting of N variables, the cardinality constraint given in a non-Conjunctive Normal Form; and encoding the cardinality constraint in Conjunctive Normal Form based on a mapping by a Perfect Hash Family, whereby said memory is modified to retain the CNF encoded cardinality constraint.
摘要翻译: 用于编码结合正常形式(CNF)中的基数约束的方法,装置和产品。 该方法包括:具有包括基数约束的布尔公式,其中与一组布尔变量相关的基数约束,由N个变量组成的变量集合,以非结合正则形式给出的基数约束; 并且基于完美哈希族的映射来编码结合正态形式中的基数约束,由此修改所述存储器以保留CNF编码的基数约束。
