An algorithm for computing theory prime implicates in first order logic
نویسندگان
چکیده
An algorithm based on consensus method to compute the set of prime implicates of a quantifier free first order formula X was presented in an earlier work. In this paper the notion of prime implicates is extended to theory prime implicates in the first order case. We provide an algorithm to compute the theory prime implicates of a Knowledge base X with respect to another knowledge base Y where both X and Y are assumed to be unquantified first order formulas. The partial correctness of the algorithm is proved.

Prime Implicates of First Order Formulas
This paper extends the notion of prime implicates to first order logic formulas without equality which are assumed to be in Skolem Conjunctive Normal Form. Using the extended notions of consensus and subsumption it is shown that the consensus-subsumption algorithm for computing prime implicates well known for propositional formulas can be conditionally lifted to first order formulas.
متن کاملComputing Theory Prime Implicates in Modal Logic
The algorithm to compute theory prime implicates, a generalization of prime implicates, in propositional logic has been suggested in [16]. In this paper we have extended that algorithm to compute theory prime implicates of a knowledge base X with respect to another knowledge base Y using [2], where Y is a propositional knowledge base and X |= Y , in modal system T and we have also proved its co...

متن کاملAn Incremental Knowledge Compilation in First Order Logic
An algorithm to compute the set of prime implicates of a quantifierfree clausal formula X in first order logic had been presented in earlier work. As the knowledge base X is dynamic, new clauses are added to the old knowledge base. In this paper an incremental algorithm is presented to compute the prime implicates of X and a clause C from π(X) ∪ C. The correctness of the algorithm is also proved.
متن کاملPrime Implicate Generation in Equational Logic
We present an algorithm for the generation of prime implicates in equational logic, that is, of the most general consequences of formulæ containing equations and disequations between first-order terms. This algorithm is defined by a calculus that is proved to be correct and complete. We then focus on the case where the considered clause set is ground, i.e., contains no variables, and devise a s...
