Deciding Full Branching Time Logic by Program Transformation [chapter]

Alberto Pettorossi, Maurizio Proietti, Valerio Senni
2010 Lecture Notes in Computer Science  
This transformation is performed by applying unfold/fold rules that preserve the perfect model of the initial program.  ...  We present a method based on logic program transformation, for verifying Computation Tree Logic (CTL * ) properties of finite state reactive systems.  ...  Introduction The branching time temporal logic CTL * is among the most popular temporal logics that have been proposed for verifying properties of reactive systems [4] .  ...

Summary: “We propose meaning-preserving translations between Lz, Ly and Ly (three modal logics in full agreement with branch- ing bisimulation), thus proving that they all have the same expres- sivity.  ...  The technique we developed to cope with this is an adaptation in a branching-time framework of the methods un- derlying D.  ... 

A polyvariant binding-time analysis for off-line partial deduction [chapter]

Maurice Bruynooghe, Michael Leuschel, Konstantinos Sagonas
1998 Lecture Notes in Computer Science  
We study the notion of binding-time analysis for logic programs. We formalise the unfolding aspect of an on-line partial deduction system as a Prolog program.  ...  Using abstract interpretation, we collect information about the run-time behaviour of the program.  ...  Leuschel are supported by the Fund for Scientific Research -Flanders Belgium (FWO).

Formalization as the Immanent Part of Logical Solving

Nikolai N. Nepejvoda
2018 Logical Investigations  
The work is devoted to the logical analysis of the problem solving by logical means.  ...  The precise solving of a precisely stated logical problem occupies only one third of the whole process of solving real problems by logical means.  ...  Disjunction ∨ can be interpreted classically if elementary properties are decidable. Implication is treated constructively as existence of a program. Nilpotent logic is linear time decidable.  ...

Strong equivalence of reversible circuits is coNP-complete [article]

Stephen P. Jordan
2013 arXiv   pre-print
It is well-known that deciding equivalence of logic circuits is a coNP-complete problem.  ...  The complexity of deciding strong equivalence, including the ancilla bits, is less obvious and may depend on gate set.  ...  By composing the triples (i, 1, β) and (i, α, 1) one then obtains an arbitrary triple (i, α, β). By simulating the full sequence of l such triples, one simulates the full branching program.  ...

Temporal stratification tests for linear and branching-time deductive databases

Christos Nomikos, Panos Rondogiannis, Manolis Gergatsoulis
2005 Theoretical Computer Science  
The second algorithm applies to branching-time temporal deductive databases (which include as a special case the linear-time ones).  ...  We demonstrate that for the temporal deductive databases we consider, temporal stratification coincides with local stratification in certain important cases in which the latter is polynomial-time decidable  ...  Now, by applying the proposed algorithm one can easily see that the above (second) program is a locally stratified one. We do not give the full transformation since it results to 13 clauses.  ...

Technical systems in logic: questions of formalization and automatic verification

А.Н. Непейвода
2013 Logical Investigations  
The questions of formalization in temporal logic and automatic analysis via computational tree transformations are discussed.  ...  In the paper technical systems with counters are considered as logical models.  ...  But the sense of temporal logics isn't restricted by only automata or program systems: they can describe any lasting-in-time process, every moment of which can be described by the classical logic.  ...

The applicability of logic program analysis and transformation to theorem proving [chapter]

D. A. Waal, J. P. Gallagher
1994 Lecture Notes in Computer Science  
Analysis and transformation techniques developed for logic programming can be successfully applied to automatic theorem proving.  ...  The specialisation techniques developed in this paper are independent of the proof system and can therefore be applied to theorem provers for any logic written as logic programs. 2  ...  Our analysis method depends heavily on techniques developed to analyse and transform logic programs.  ...

A Tableau System for Right Propositional Neighborhood Logic over Finite Linear Orders: An Implementation [chapter]

Davide Bresolin, Dario Della Monica, Angelo Montanari, Guido Sciavicco
2013 Lecture Notes in Computer Science  
Interval temporal logics are quite expressive temporal logics, which turn out to be difficult to deal with in many respects.  ...  We focus our attention on the logic of Allen's relation meets, a.k.a. Right Propositional Neighborhood Logic (RPNL), interpreted over finite linear orders.  ...  Acknowledgments The authors acknowledge the support from the Spanish fellowship program  ...

We also provide a comparison of features of the temporal logics discussed.  ...  In this paper we analyse real-time and probabilistic temporal logics which have been widely used in this field.  ...  This work was partially supported by EPSRC research project EP/F033567.  ...
