"Abstract Solvers for Dung's Argumentation Frameworks";
Argument & Computation, 9 (2018), 1; S. 41 - 72.



Kurzfassung englisch:
Abstract solvers are a quite recent method to uniformly describe algorithms
in a rigorous formal way via graphs. Compared to traditional methods like
pseudo-code descriptions, abstract solvers have several advantages. In
particular, they provide a uniform formal representation that allows for
precise comparisons of different algorithms. Recently, this new methodology
has proven successful in declarative paradigms such as Propositional
Satisfiability and Answer Set Programming. In this paper, we apply this
machinery to Dung's abstract argumentation frameworks. We first provide
descriptions of several advanced algorithms for the preferred semantics in
terms of abstract solvers. We also show how it is possible to obtain new
abstract solutions by "combining" concepts of existing algorithms by means
of combining abstract solvers. Then, we implemented a new solving procedure
based on our findings in cegartix, and call it cegartix+. We finally show
that cegartix+ is competitive and complementary in its performance to cegartix
on benchmarks of the first and second argumentation competition.
