Decidability and Undecidability Results for Propositional Schemata [PDF]
We define a logic of propositional formula schemata adding to the syntax of propositional logic indexed propositions (e.g., pi) and iterated connectives ∨ or ∧ ranging over intervals parameterized by arithmetic variables (e.g., ∧i-1n pi, where n is a ...

Does Advice Help to Prove Propositional Tautologies? [PDF]
One of the starting points of propositional proof complexity is the seminal paper by Cook and Reckhow [6], where they defined propositional proof systems as poly-time computable functions which have all propositional tautologies as their range. Motivated

The curse genre of ’Kargys’ in the Kazakh language: Is the belief in the magical power of the word still preserved? [PDF]
The speech genre of curse analyzed in the article belongs to the most ancient genres of oral communication in Kazakh culture. It is based on belief in the magical function of the word, in the ability to bring harm and evil to the cursed with the help of ...

Algorithms for testing the satisfiability of propositional formulae
It is experimentally shown that the satisfiability for Horn clauses algorithm (Dowling, Gallier) is efficient. The authors propose two relaxation schemes which map instances of a satisfiability problem for propositional formulae into problem instances for Horn clauses.

On Propositional Encoding of Distinction Property in Finite Sets
In the paper we describe a new propositional encoding procedure for the property that all objects comprising some finite set are distinct. For the considered class of combinatorial problems it is sufficient to represent the elements of such set by their ...

The validity degree vectors of formulae in two-valued predicate logic [PDF]
By means of infinite product of uniformly distributed probability spaces of cardinal , the concept of -validity degrees and validity degree vectors of formulae in two-valued predicate logic are introduced. It is proved that the validity degree vectors of

Solving QBF by Abstraction [PDF]
Many verification and synthesis approaches rely on solving techniques for quantified Boolean formulas (QBF). Consequently, solution witnesses, in the form of Boolean functions, become more and more important as they represent implementations or ...

Evaluating state-of-the-art # SAT solvers on industrial configuration spaces
Product lines are widely used to manage families of products that share a common base of features. Typically, not every combination (configuration) of features is valid.

Simplifying Inductive Schemes in Temporal Logic [PDF]
In propositional temporal logic, the combination of the connectives "tomorrow" and "always in the future" require the use of induction tools. In this paper, we present a classification of inductive schemes for propositional linear temporal logic that ...

Boolean basis, formula size, and number of modal operators [PDF]
Is it possible to write significantly smaller formulae when using Boolean operators other than those of the De Morgan basis (and, or, not, and the constants)?
