We present a new method for clausal theorem proving, named SGGS from semantically-guided goal-sensitive reasoning. SGGS generalizes to first-order logic the conflict-driven clause learning (CDCL) procedure for propositional satisfiability. Starting from an initial interpretation, used for semantic guidance, SGGS employs a sequence of constrained clauses to represent a candidate model, ...

SGGS (Semantically-Guided Goal-Sensitive reasoning) is a clausal theorem-proving method, which generalizes to first-order logic the Davis-Putnam-Loveland-Logemann procedure with conflict-driven clause learning (DPLL-CDCL). SGGS starts from an initial interpretation, and works towards modifying it into a model of a given set of clauses, reporting unsatisfiability if there is no model. The ...

Ordered semantic hyper-linking (OSHL) is a first-order theorem prover that tries to take advantage of the speed of propositional theorem proving techniques. It instantiates first-order clauses to ground clauses, and applies propositional techniques to these ground clauses. OSHL-U extends OSHL with rules for unit clauses to speed up the instantiation ...

We present a satisfiability tester QSAT for quantified Boolean formulae and a restriction Q SAT CNF of QSAT to unquantified conjunctive normal form formulae. QSAT makes use of procedures which replace subformulae of a formula by equivalent formulae. By a sequence of such replacements, the original formula can be simplified ...

Identifying relevant clauses before attempting a proof may lead to more efficient automated theorem proving. Relevance is here defined relative to a given set of clauses S and one or more distinguished sets of support T . The role of a set of support T can be played by the ...

A family of tableau methods, called i>ordered semantic hyper (i>OSH ) i>tableau methods for first-order theories with function symbols, is presented. These methods permit semantic information to guide the search for a proof. They also may make use of orderings on literals, clauses, and interpretations to guide the search. In ...

Mechanized systems for equational inference often produce many terms that are permutations of one another. We propose to gain efficiency by dealing with such sets of terms in a uniform manner, by the use of efficient general algorithms on permutation groups. We show how permutation groups arise naturally in equational ...

The ordered semantic hyper-linking strategy is complete for first-order logic and accepts a user-specified natural semantics that guides the search for a proof. Any semantics in which the meanings of the function and predicate symbols are computable on ground terms may be used. This instance-based strategy is efficient on near-propositional ...

The way in which a theorem prover handles definitions can have a significant effect on its performance. Many first-order clause form theorem provers perform badly on theorems such as those from set theory that are proven largely by expanding definitions. The technique of using replacement rules permits automatic proofs of ...

Mechanical theorem provers are becoming increasingly more powerful, and we believe that it is time to examine whether certain tasks that have formerly been accomplished by other means can now be performed efficiently by a theorem prover. One such task is classification in description logic-based knowledge representation systems. Description logic ...

Unfailing completion is a commonly used technique for equational reasoning. For equational problems with associative and commutative functions, unfailing completion often generates a large number of rewrite rules. By comparing it with a ground completion procedure, we show that many of the rewrite rules generated are redundant. A set of ...

In this paper, we present a novel first order theorem proving strategy - ordered semantic hyper linking. Ordered semantic hyper linking (OSHL) is an instance-based refutational theorem proving strategy. It is sound and complete. OSHL has an efficient propositional decision procedure. It solves first order problems by reducing them to ...

The Replacement Rule Theorem Prover (RRTP) is an instance-based, refutational, first-order clausal theorem prover. The prover is motivated by the idea of selectively replacing predicates by their definitions, and operates by selecting relevant instances of the input clauses. The relevant instances are grounded, if necessary, and tested for unsatisfiability by ...

CLIN-S is an instance-based, clause-form first-order theorem prover. CLIN-S employs three inference procedures: semantic hyper-linking, which uses semantics to guide the proof search and performs well on non-Horn parts of the proofs involving small literals, rough resolution, which removes large literals in the proofs, and UR resolution, which proves the ...

We first show that ground term-rewriting systems can be completed in a polynomial number of rewriting steps, if the appropriate data structure for terms is used. We then apply this result to study the lengths of critical pair proofs in non-ground systems, and obtain bounds on the lengths of critical ...
