Some results have been obtained on the issue of updating a logic program which encodes a set of models, to obtain a new program whose models are the desired updates of the initial models.  ...  The updating of theory models is governed by their update rules and also by in- ertia applied to those literals not directly affected by the update program.  ... 

A Generalised Semantics for Belief Updates - An Equivalence-based Approach

Jorge Hernández, Juan C. Acosta
2013 Ciencias Huasteca Boletín Científico de la Escuela Superior de Huejutla  
en la literatura, la revisión y actualización de creencias y de bases del conocimiento, es un tema importante, aún no resuelto en la representación del conocimiento y del razonamiento en la Answer Set Programming  ...  Last but not least, the associated models S of the new knowledge base correspond to the answer sets of a •-update program as follows.  ...  Although ASP is a strong theoretical framework to represent knowledge, it can't model changes to that knowledge by itself, nor can it represent conflict situations amongst an agent and its dynamic environment  ...

Modular BDI architecture

Peter Novák, Jürgen Dix
2006 Proceedings of the fifth international joint conference on Autonomous agents and multiagent systems - AAMAS '06  
The underlying architecture of such programming languages has to be robust enough to support various approaches to knowledge representation and agent reasoning models.  ...  The connections between the components of such a BDI system are provided by interaction rules.  ...  Although the semantics of interaction rules is dened for ground query and update formulas, a practical programming system has to handle also non-ground interaction rules.  ...

KupC: A Formal Tool for Modeling and Verifying Dynamic Updating of C Programs [chapter]

Jiaqi Qian, Min Zhang, Yi Wang, Kazuhiro Ogata
2019 Lecture Notes in Computer Science  
In this paper, we present a formal tool called KupC for modeling and verifying dynamic updating of C programs. The tool is built on K-a formal semantic framework for programming languages.  ...  The formalization automatically yields an interpreter and several verification tools, which can be used to formally analyze the correctness of dynamic updating for C programs.  ...  KUPC Usage KupC is equipped with an interpreter to execute updatable C programs, a state space explorer to search for all possible updating results, and an LTL model checker to verify temporal properties  ...

Computing Environment-Aware Agent Behaviours with Logic Program Updates [chapter]

José J. Alferes, Antonio Brogi, João A. Leite, Luís M. Pereira
2002 Lecture Notes in Computer Science  
We show how such language can be used to model the more reactive behaviours, while keeping the more deliberative features provided by its underlying Dynamic Logic Programming paradigm.  ...  Logic program updates are specified, in our setting, by the language of updates LUPS.  ...  One difference between such approach and ours is that in [21] the semantics is a proof-theoretic operational one, while our approach provides a declarative, model-theoretic characterization of environment-aware  ...

AGM postulates in Answer Sets

Juan Carlos Acosta Guadarrama
2008 Latin-American Workshop on Non-Monotonic Reasoning  
As a result, various researchers have proposed Answer Set Programming as one of their key components to set up their approaches.  ...  Revising and updating beliefs and knowledge bases is an important topic in knowledge representation and reasoning that requires a solid theoretical basis.  ...  Last, the associated models S of an epistemic state (an updating pair) corresponds to the answer sets of a • o -update program as follows. Definition 2 (• o -update Answer Set).  ...

Advances in Computer Science and Artificial Intelligence

Fernando Zacarías Flores, José R. Arrazola Ramírez, Oscar Hernán Estrada-Estrada
2007 Engineering Letters  
We compare our approach with the well-known upd operator (due to Eiter et al.) . Finally, we discuss how to compute our updated models by means of a simple transformation to ordered disjunctions.  ...  The reason is that a semantics is customarily defined by specifying a certain class of intended models which are merely set-theoretic entries used to interpret the vocabulary of the program (eg. minimal  ...

Operational Semantics for DyLPs [chapter]

2005 Lecture Notes in Computer Science  
Theoretical research has spent some years facing the problem of how to represent and provide semantics to updates of logic programs.  ...  shown to be a useful paradigm for modelling NP-complete problems.  ...  Moreover, the transformed program can be used also for "reading" a DyLP as a normal logic program, a task for which a program transformation with many more auxiliary rules and predicates would not be suitable  ...

Attribute Computations in the DPoPb Graph Transformation Engine

Hanh Nhi Tran, Christian Percebois, Ali Abou Dib, Louis Féraud, Sergei Soloviev
2010 Electronic Communications of the EASST  
However, for the sake of efficiency considerations and convenient uses, these systems do not generally implement the whole attribute computations but rely on programs written in a host language.  ...  In previous works we introduced the Double Pushout Pullback (DPoPb) framework which integrates attributed graph rewriting and computation on attributes in a unified categorical approach.  ...  GraBaTs 2010 11 / 14 The DPoPb prototype To validate the theoretical model DPoPb, we have developed a prototype in Haskell language.  ...

A Brief History of Updates of Answer-Set Programs

Splitting and updating hybrid knowledge bases

2011 Theory and Practice of Logic Programming  
AbstractOver the years, nonmonotonic rules have proven to be a very expressive and useful knowledge representation paradigm.  ...  In this paper, motivated by real world applications, we introduce an update operator for a large class of hybrid knowledge bases where both the DL component as well as the rule component are allowed to  ...  In page 3 the authors wrote: "While classical updates are performed on the models of a knowledge base, .... , forces rule update methods to refer to the syntactic structure of underlying programs."  ...
