Tableau Calculi for Preference-Based Conditional Logics

چکیده
In this paper we develop labelled and uniform tableau methods for some fundamental system of propositional conditional logics. We consider the well-known system CE (that can be seen as a generalization of preferential nonmonotonic logic), and some related systems. Our tableau proof procedures are based on a possible-worlds structures endowed with a family of preference relations. The tableau procedure gives the first practical decision procedure for CE.

Tableau Calculi for KLM Logics: extended version
We present tableau calculi for some logics of nonmonotonic reasoning, as defined by Kraus, Lehmann and Magidor. We give a tableau proof procedure for all KLM logics, namely preferential, loop-cumulative, cumulative and rational logics. Our calculi are obtained by introducing suitable modalities to interpret conditional assertions. We provide a decision procedure for the logics considered, and w...
متن کاملAnalytic Tableaux for KLM Preferential and Cumulative Logics
We present tableau calculi for some logics of default reasoning, as defined by Kraus, Lehmann and Magidor. We give a tableau proof procedure for preferential and cumulative logics. Our calculi are obtained by introducing suitable modalities to interpret conditional assertions. Moreover, they give a decision procedure for the respective logics and can be used to establish their complexity.
متن کاملSynthesising and Implementing Tableau Calculi for Interrogative Epistemic Logics
This paper presents a labelled tableau approach for deciding interrogative-epistemic logics (IEL). Tableau calculi for these logics have been derived using a recently introduced tableau synthesis method. We also consider an extension of the framework for a setting with questioning modalities over sequences of formulae called sequential questioning logic (SQL). We have implemented the calculi us...
متن کاملTableau Calculi for Hybrid Logics
Hybrid logics were proposed in [15] as a way of boosting the expressivity of modal logics via a novel mechanism: adding labels for states in Kripke models and viewing these labels as formulae. In addition, hybrid logics may contain quanti ers to bind the labels. Thus, hybrid logics have both Kripke semantics and a rst-order binding apparatus. We present pre xed tableau calculi for weak hybrid l...
متن کاملA Fibred Tableau Calculus for BDI Logics
In [12,16] we showed how to combine propositional BDI logics using Gabbay’s fibring methodology. In this paper we extend the above mentioned works by providing a tableau-based decision procedure for the combined/fibred logics. To achieve this end we first outline with an example two types of tableau systems, (graph & path), and discuss why both are inadequate in the case of fibring. Having done...
