Temporal Equilibrium Logic

چکیده

This talk introduces the Temporal Equilibrium Logic, a combination of standard Linear Temporal Logic with a formalism called Equilibrium Logic, used to to characterise logic programming under the answer set semantics. The talk will explain the basic syntax and semantics together with some elementary properties and recent results. Some motivating examples will show the potential utility of nonmonotonic temporal reasoning for different application scenarios like action domains or context evolution. Short Biography. Pedro Cabalar is an associate professor of the Department of Computer Science at the University of Corunna, Spain, and organizes the MSc and PhD degrees in Computing research offered by that department. He graduated in 1993 in Computer Science in the Politechnic University of Madrid and received his PhD degree from the University of Corunna in 2001, on the topic of causality in action domains. His research is mostly related to logical approaches for Knowledge Representation in Artificial Intelligence, being particularly interested in Nonmonotonic Reasoning and Logic Programming under the Answer Set semantics. He has both published and actively participated as Program Committee or reviewer in main conferences (ICLP, LPNMR, KR, AAAI, ECAI, JELIA), journals (TPLP, AIJ, AMAI) and specialized workshops (NMR, ASP, ASPOCP) of these areas. He has also conducted several research projects in Answer Set Programming, in coordination with other groups in Spain. ? I am especially grateful to David Pearce, Agustı́n Valverde, Felicidad Aguado, Gilberto Pérez, Conchi Vidal and Martı́n Diéguez for their direct implication in many of the results related to this talk, and to the workshop organisers Alessandra Mileo and Michael Fink for their kind invitation.

An infinitary encoding of temporal equilibrium logic

This paper studies the relation between two recent extensions of propositional Equilibrium Logic, a well-known logical characterisation of Answer Set Programming. In particular, we show how Temporal Equilibrium Logic, which introduces modal operators as those typically handled in Linear-Time Temporal Logic (LTL), can be encoded into Infinitary Equilibrium Logic, a recent formalisation that allo...

Automata-Based Computation of Temporal Equilibrium Models

Temporal Equilibrium Logic (TEL) is a formalism for temporal logic programming that generalizes the paradigm of Answer Set Programming (ASP) introducing modal temporal operators from standard Linear-time Temporal Logic (LTL). In this paper we solve some problems that remained open for TEL like decidability, bounds for computational complexity as well as computation of temporal equilibrium model...

Numerical Analysis of Stability for Temporal Bright Solitons in a PT-Symmetric NLDC

PT-Symmetry is one of the interesting topics in quantum mechanics and optics. One of the demonstration of PT-Symmetric effects in optics is appeared in the nonlinear directional coupler (NLDC). In the paper we numerically investigate the stability of temporal bright solitons propagate in a PT-Symmetric NLDC by considering gain in bar and loss in cross. By using the analytical solutions of pertu...

Effect of Relative Phase on the Stability of Temporal Bright Solitons in a PT- Symmetric NLDC

In this paper we numerically investigate the effect of relative phase on thestability of temporal bright solitons in a Nano PT- Symmetric nonlinear directionalcoupler (NLDC) by considering gain in bar and loss in cross. We also study the effect ofrelative phase on the output perturbed bright solitons energies, in the range of   0 to 180 . By using perturbation theory three eigenfunctions an...

Temporal Answer Set Programming

Answer Set Programming (ASP) has become a popular way for representing different kinds of scenarios from knowledge representation in Artificial Intelligence. Frequently, these scenarios involve a temporal component which must be considered. In ASP, time is usually represented as a variable whose values are defined by an extensional predicate with a finite domain. Dealing with a finite temporal ...

Temporal Equilibrium Logic: A First Approach

In this paper we introduce an extension of Equilibrium Logic (a logical characterisation of the Answer Set Semantics for logic programs) consisting in the inclusion of modal temporal operators, as those used in Linear Temporal Logic. As a result, we obtain a very expressive formalism that allows nonmonotonic reasoning for temporal domains. To show an example of its utility, we present a transla...
