Horn Renamability and Hypergraphs

Dušan Hvalica

Abstract


Satisfiability testing in the context of directed hypergraphs is discussed. A characterization of Horn-renamable formulae is given and a subclass of SAT that belongs to $\QTR{cal}{P}$ is described. An algorithm for Horn renaming with linear time complexity is presented.
