Horn-satisfiability

A polynomial-time algorithm for Horn satisfiability is based on the rule of unit propagation: if the formula contains a clause composed of a single literal (a unit clause), then all clauses containing (except the unit clause itself) are removed, and all clauses containing have this literal removed. Meer weergeven In formal logic, Horn-satisfiability, or HORNSAT, is the problem of deciding whether a given set of propositional Horn clauses is satisfiable or not.
