• KurzfassungAbstract
  In this paper we answer the open question for the existence of a more compact encoding from Pseudo-Boolean constraints into CNF that maintains generalized arc consistency by unit propagation, formalized by Bailleux et al. In contrast to other encodings our approach is defined in an abstract way and we present a concrete instantiation, resulting in a space complexity of O(n2 log2(n) log(wmax)) clauses in contrast to O(n3 log(n) log(wmax)) clauses generated by the previously best known encoding that maintains generalized arc consistency.
