چکیده

This paper introduces a variant of clausal normal form tableaux that we call “hyper tableaux”. Hyper tableaux keep many desirable features of analytic tableaux while taking advantage of the central idea from (positive) hyper resolution, namely to resolve away all negative literals of a clause in a single inference step. Another feature of the proposed calculus is the extensive use of universally quantified variables. This enables new efficient forward-chaining proof procedures for full first order theories as variants of tableaux calculi.

HyperS Tableaux - Heuristic Hyper Tableaux

Several syntactic methods have been constructed to automate theorem proving in first-order logic. The positive (negative) hyper-resolution and the clause tableaux were combined in a single calculus called hyper tableaux in [1]. In this paper we propose a new calculus called hyperS tableaux which overcomes substantial drawbacks of hyper tableaux. Contrast to hyper tableaux, hyperS tableaux are e...

Redundancy for rigid clausal tableaux

Redundancy is a substantial concept when avoiding endless computation in theorem proving methods. In this paper, we are targeting a special class of tableau calculi, namely rigid clausal tableaux. These tableaux are (1) clausal in the sense that they consist solely of literals, and are (2) rigid in the sense that they employ rigid variables. Such calculi are e.g. rigid hyper tableaux [7] and mu...

Introducing general redundancy criteria for clausal tableaux, and proposing resolution tableaux

Hyper tableau calculi are well-known as attempts to combine hyper-resolution and tableaux. Besides their soundness and completeness, it is also important to give an appropriate redundancy criterion. The task of such a criterion is to filter out “unnecessary” clauses being attached to a given tableau. This is why we investigate what redundancy criteria can be defined for clausal tableaux, in gen...

Constrained Hyper Tableaux

Hyper tableau reasoning is a version of clausal form tableau reasoning where all negative literals in a clause are resolved away in a single inference step. Constrained hyper tableaux are a generalization of hyper tableaux, where branch closing substitutions, from the point of view of model generation, give rise to constraints on satisfying assignments for the branch. These variable constraints...

Hyper Tableaux and Disjunctive Logic Programming

For disjunctive logic programs (DLPs) there are several proposals for deening interpreters, There have also been diierent approaches to assign least xpoints to DLPs. This paper proves that there exist an eecient proof procedure, namely hyper tableaux, which can be understood as a direct implementation of some of the well known xpoint iteration techniques. We show how a hyper tableaux refutation...
