A new positive-unit theorem-proving procedure for equational Horn clauses is presented. It uses a term ordering to restrict paxamodulation to potentiallymaximal sides of equations...
We extend Fagin’s result on the equivalence between functional dependencies in relational databases and propositional Horn clauses. It is shown that this equivalence still holds...
We study the parameterized complexity of detecting backdoor sets for instances of the propositional satisfiability problem (SAT) with respect to the polynomially solvable classes ...
Cryptographic protocols with single blind copying were defined and modeled by Comon and Cortier using the new class C of first order clauses, which extends the Skolem class. They s...
