Incremental and Modular Context-sensitive Analysis [article]

Isabel Garcia-Contreras, Jose F. Morales, Manuel V. Hermenegildo
2020 arXiv   pre-print
This paper describes, implements, and evaluates an algorithm that performs efficient context-sensitive analysis incrementally on modular partitions of programs.  ...  This has been achieved to date through incremental global analysis fixpoint algorithms that achieve cost reductions at fine levels of granularity, such as changes in program lines.  ...  Incremental algorithms compute an updated output from a previous output and a difference on the input data, which the hope that the process is (computationally) cheaper than computing from scratch a new  ...

An Incremental Approach to Abstraction-Carrying Code [chapter]

Elvira Albert, Puri Arenas, Germán Puebla
2006 Lecture Notes in Computer Science  
Abstraction-Carrying Code (ACC) has recently been proposed as a framework for proof-carrying code (PCC) in which the code supplier provides a program together with an abstraction (or abstract model of  ...  In the context of ACC, we propose an incremental approach to PCC for the generation of certificates and the checking of untrusted updates of a (trusted) program, i.e., when a producer provides a modified  ...  During analysis, dependencies are used for achieving efficient implementations of fixed-point re-computations.  ...

The Matrix Approach for Abstract Argumentation Frameworks [chapter]

Yuming Xu, Claudette Cayrol
2015 Lecture Notes in Computer Science  
In particular, an efficient approach for determining the basic extensions has been developed using two types of standard matrix.  ...  The second one enables to decompose an extension into several extensions of different sub-argumentation frameworks.  ...  The matrix approach can be used for other applications. One direction for further research is to study the structural properties and status-based properties of dynamics of AFs as defined by [10] .  ...

Initial sets in abstract argumentation frameworks

Yuming Xu, Claudette Cayrol
2018 Journal of Applied Non-Classical Logics  
Another one is directionality which can be employed for the study of dynamics of argumentation.  ...  Dung's abstract argumentation provides us with a general framework to deal with argumentation, non-monotonic reasoning and logic programming.  ...  Several works have proposed efficient ways for handling dynamics, such as [Lia11] which introduces the divisionbased method, and [Xu15] where a matrix approach allows for a decomposition of traditional  ...

Senses of 'argument' in instantiated argumentation frameworks

Adam Wyner, Trevor Bench-Capon, Paul Dunne, Federico Cerutti
2015 Argument & Computation  
Our framework retains the theoretical and computational benefits of an abstract AF, distinguishes senses of argument, and efficiently computes extensions.  ...  As a consequence of the approach, we reduce the effort of computing argumentation extensions, which is in contrast to other approaches.  ...  Conflict of interest disclosure statement No potential conflict of interest was reported by the authors. Note 1.  ...
