Rediscovering Argumentation Principles Utilizing Collective Attacks

no code implementations6 May 2022 Wolfgang Dvořák, Matthias König, Markus Ulbricht, Stefan Woltran

We extend the principle-based approach to Argumentation Frameworks with Collective Attacks (SETAFs) and provide a comprehensive overview of common principles for their semantics.

Aspartix-V21

no code implementations7 Sep 2021 Wolfgang Dvořák, Matthias König, Johannes P. Wallner, Stefan Woltran

In this solver description we present ASPARTIX-V, in its 2021 edition, which participates in the International Competition on Computational Models of Argumentation (ICCMA) 2021.

Expressiveness of SETAFs and Support-Free ADFs under 3-valued Semantics

no code implementations7 Jul 2020 Wolfgang Dvořák, Atefeh Keshavarzi Zafarghandi, Stefan Woltran

Generalizing the attack structure in argumentation frameworks (AFs) has been studied in different ways.

Algorithms and Conditional Lower Bounds for Planning Problems

no code implementations19 Apr 2018 Krishnendu Chatterjee, Wolfgang Dvořák, Monika Henzinger, Alexander Svozil

For the sequential target problem, we present a linear-time algorithm for graphs, a sub-quadratic algorithm for MDPs, and a quadratic conditional lower bound for games on graphs.
