Satisfiability vs. Finite Satisfiability in Elementary Modal Logics [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
We study elementary modal logics, i.e. modal logic considered over first-order definable classes of frames. The classical semantics of modal logic allows infinite structures, but often practical applications require to restrict our attention to finite ...

Testing satisfiability [PDF]

open access: yesJournal of Algorithms, 2003
Summary: Let \(\Phi\) be a set of general boolean functions on \(n\) variables, such that each function depends on exactly \(k\) variables, and each variable can take a value from \([1,d]\). We say that \(\Phi\) is \(\varepsilon\)-far from satisfiable, if one must remove at least \(\varepsilon n^k\) functions in order to make the set of remaining ...

An Effective SAT Solver Utilizing ACO Based on Heterogenous Systems

open access: yesIEEE Access, 2020
This paper presents new parallel strategies for preprocessing and solving the issue of Boolean Satisfaction (SAT) on Heterogeneous systems of multicore and many-core CPU and Graphics Processing Unit (GPU) using Open Multi-Processor (OpenMP) and NVIDIA ...

Unary negation [PDF]

open access: yesLogical Methods in Computer Science, 2013
We study fragments of first-order logic and of least fixed point logic that allow only unary negation: negation of formulas with at most one free variable.

Model Abstraction for Discrete-Event Systems Using a SAT Solver

open access: yesIEEE Access, 2023
Model abstraction for finite state automata is beneficial to reduce the complexity of discrete-event systems (DES), enhance the readability and facilitate the control synthesis and verification of DES.

Fullness and Decidability in Continuous Propositional Logic

open access: yesMathematics, 2022
In this paper we consider general continuous propositional logics and prove some basic properties about them. First, we characterize full systems of continuous connectives of the form {¬,∸,f} where f is a unary connective.

Complete SAT based Cryptanalysis of RC5 Cipher

open access: yesJournal of Information and Organizational Sciences, 2020
Keeping the proper security level of ciphers used in communication networks is today a very important problem. Cryptanalysts ensure a constant need for improvement complexity and ciphers' security by trying to break them.

Normal form of formulas of pure hybrid logic

open access: yesLietuvos Matematikos Rinkinys, 2021
In this paper,we study a transformationof pure hybrid logic formulae,which do not have binding operator, into an equivalent normal form, which does not have any satisfiability operators in the scope of another satisfiability operator.

A Fine-Grained Hierarchy of Hard Problems in the Separated Fragment [PDF]

open access: yes, 2017
Recently, the separated fragment (SF) has been introduced and proved to be decidable. Its defining principle is that universally and existentially quantified variables may not occur together in atoms.
