Proceedings Article
Abstract dialectical frameworks revisited
TL;DR: It is shown how the existing definitions of stable and preferred semantics can be improved and generalized to arbitrary frameworks and preference handling methods for ADFs are introduced, allowing for both reasoning with and about preferences.
Journal ArticleDOI
Methods for solving reasoning problems in abstract argumentation - A survey
TL;DR: This survey gives an overview on different methods for solving reasoning problems in abstract argumentation and compare their particular features, and highlights available state-of-the-art systems for Abstract argumentation, which put these methods to practice.
Journal ArticleDOI
Complexity-sensitive decision procedures for abstract argumentation
TL;DR: In this paper, a generic approach for reasoning over argumentation frameworks is proposed based on the concept of complexity-sensitivity, which allows instantiations of the generic framework via harnessing in an iterative way current sophisticated Boolean satisfiability solver technology for solving the considered argumentation reasoning problems.

Geodesic patterns
Helmut Pottmann,Qixing Huang,Bailin Deng,Alexander Schiftner,Martin Kilian,Leonidas J. Guibas,Johannes Peter Wallner +6 more
TL;DR: In this article, the evolution of geodesic curves is used for local studies and simple patterns; the level set formulation can deal with the global layout of multiple patterns of Geodesics; and finally, Geodesic vector fields allow us to interactively model geodeic patterns and perform surface segmentation into panelizable parts.
