Algorithms and Complexity Results for Persuasive Argumentation
Eun Jung Kim, Sebastian Ordyniak, Stefan Szeider
The study of arguments as abstract entities and their interaction as introduced by Dung (Artificial Intelligence 177, 1995) has become one of the most active research branches with…
Augmenting Tractable Fragments of Abstract Argumentation
Sebastian Ordyniak, Stefan Szeider
We present a new and compelling approach to the efficient solution of important computational problems that arise in the context of abstract argumentation. Our approach makes known…
Kernels for Global Constraints
Serge Gaspers, Stefan Szeider
Bessiere et al. (AAAI'08) showed that several intractable global constraints can be efficiently propagated when certain natural problem parameters are small. In particular, the com…
Limits of Preprocessing
Stefan Szeider
We present a first theoretical analysis of the power of polynomial-time preprocessing for important combinatorial problems from various areas in AI. We consider problems from Const…
