Center node: "encoding cardinality constraints using generalized selection networks"
  Abstract: 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 or pairwise comparator networks. We use similar ideas, but we extend the model of comparator networks so that the basic components are not only comparators (2-sorters) but more general $m$-sorters, for $m \geq 2$. The inputs are organized into $m$ columns, in which elements are recursively selected and, after that, columns are merged using an idea of multi-way merging. We present two algorithms parametrized by $m \geq 2$. We call those networks $m$-Wise Selection Network and $m$-Odd-Even Selection Network. We give detailed construction of the mergers when $m=4$. The construction can be directly applied to any values of $k$ and $n$. The proposed encoding of sorters is standard, therefore the arc-consistency is preserved. We prove correctness of the constructions and present the theoretical and experimental evaluation, which show that the new encodings are competitive to the other state-of-art encodings.
