Jan 1, 2011 · The decision algorithm for β-acyclic formulas is based on a special type of Davis-Putnam resolution where each resolvent is a subset of a parent ...
We show that satisfiability of CNF formulas with so-called “β-acyclic hypergraphs” can be decided in polynomial time. We also study the parameterized complexity ...
