Changelog

1.1 → 2.0.0.0

Breaking changes

• Fixed groundedF infinite-loop bug: groundedF now correctly applies the characteristic function at each step instead of recursing with unchanged arguments. Code relying on groundedF' as a workaround can switch back to groundedF.

• CLI rewritten: The dungell executable now uses optparse-applicative instead of cmdargs. Command-line flags have changed:

  • Semantics are selected via --grounded, --preferred, --stable, --semi-stable, or --all

Improvements

• Upgraded to cabal-version: 3.0 format
• Relaxed containers upper bound to build on GHC 9.4+
• Added Language.Dung convenience re-export module
• Added test suite (tasty + QuickCheck + doctest)
• Added GitHub Actions CI for GHC 9.4, 9.6, 9.8, 9.10
• Fixed all -Wall warnings
• Removed dependency on unmaintained cmdargs library
• Converted documentation to Markdown

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.
