Diversity of Extensions in Abstract Argumentation
Johannes K. Fichte, Markus Hecher, Yasir Mahmood +1
Argumentation is an important topic of AI for modelling and reasoning about arguments. In abstract argumentation, we consider directed graphs, so-called argumentation frameworks (A…
Structure-Aware Encodings of Argumentation Properties for Clique-width
Yasir Mahmood, Markus Hecher, Johanna Groven +1
Structural measures of graphs, such as treewidth, are central tools in computational complexity resulting in efficient algorithms when exploiting the parameter. It is even known th…
Complexity of Faceted Explanations in Propositional Abduction
Johannes Schmidt, Mohamed Maizia, Victor Lagerkvist +1
Abductive reasoning is a popular non-monotonic paradigm that aims to explain observed symptoms and manifestations. It has many applications, such as diagnosis and planning in artif…
Facets in Argumentation: A Formal Approach to Argument Significance
Johannes Fichte, Nicolas Fröhlich, Markus Hecher +4
Argumentation is a central subarea of Artificial Intelligence (AI) for modeling and reasoning about arguments. The semantics of abstract argumentation frameworks (AFs) is given by…
The Model Counting Competitions 2021-2023
Johannes K. Fichte, Markus Hecher
Modern society is full of computational challenges that rely on probabilistic reasoning, statistics, and combinatorics. Interestingly, many of these questions can be formulated by…
Counting and Reasoning with Plans
David Speck, Markus Hecher, Daniel Gnad +2
Classical planning asks for a sequence of operators reaching a given goal. While the most common case is to compute a plan, many scenarios require more than that. However, quantita…
