An implementation of Dung's argumentation frameworks, an abstract argumentation model used to either directly represent conflicting information, or used as a translation target for more complex (structured) argumentation models. For an introduction to Dung's frameworks see http://en.wikipedia.org/wiki/Argumentation_framework and Dung's paper from 1995: "On the acceptability of arguments and its fundamental role in nonmonotonic reasoning, logic programming, and n-person games", Artificial Intelligence 77: 321-357. For the papers accompanying this library see "Towards a framework for the implementation and verification of translations between argumentation models" and "A principled approach to the implementation of argumentation models", available at http://www.cs.nott.ac.uk/~bmv/Dung/.

Changes

1.0.0.1 => 1.1
==============
This package version is now compatible with the command-line application for
the ICCMA competition. See: https://github.com/nebasuke/DungICCMA and the
competition website: http://argumentationcompetition.org/2015/index.html

This package has again been significantly extended and now includes:

* Strict version of the grounded fixpoint semantics.

* Definitions of what it means to be a preferred and stable extension.

* Naive implementations of complete, preferred and stable semantics using
the characteristic function. The fixpoint definitions are actually FASTER
than the fancy algorithm implementation.

* Included the fast implementations of intersect, nub and (\\) by Niklas
Hambuechen.

* Added some clarifying text for the "complete" labelling.

1.0 => 1.0.0.1
==============
* Fixed the record declaration in Main.hs.

* Added an example file.

0.9 => 1.0
=============
This package version is now compatible with the translation package CarneadesIntoDung.
See http://hackage.haskell.org/package/CarneadesIntoDung/

This package has furthermore been significantly extended and now includes:

* Preferred, stable and semi-stable semantics along with all definitions from
Caminada's paper "An Algorithm for Computing Semi-Stable Semantics".

* An Input module, allowing files in standard CEGARTIX/PrefSat format to be parsed.

* An Output module, allowing AFs in this package to be outputted in standard
CEGARTIX/PrefSat format.

* A main executable, allowing input files to be read, argumentation frameworks
to be outputted and evaluated.
