Extended Version of: On the Structural Hardness of Answer Set Programming: Can Structure Efficiently Confine the Power of Disjunctions?

no code implementations5 Feb 2024 Markus Hecher, Rafael Kiesel

Our results provide an in-depth hardness study, relying on a novel reduction from normal to disjunctive programs, trading the increase of complexity for an exponential parameter compression.

"What if?" in Probabilistic Logic Programming

1 code implementation24 May 2023 Rafael Kiesel, Kilian Rückschloß, Felix Weitkämper

A ProbLog program is a logic program with facts that only hold with a specified probability.

Contextual Reasoning for Scene Generation (Technical Report)

no code implementations3 May 2023 Loris Bozzato, Thomas Eiter, Rafael Kiesel, Daria Stepanova

In this paper, we show how to apply our theoretical work to real autonomous-vehicle scene data.

Efficient Knowledge Compilation Beyond Weighted Model Counting

1 code implementation16 May 2022 Rafael Kiesel, Pietro Totis, Angelika Kimmig

We introduce Second Level Algebraic Model Counting (2AMC) as a generic framework for these kinds of problems.

Quantitative and Stream Extensions of Answer Set Programming

no code implementations17 Sep 2021 Rafael Kiesel

Answer Set Programming has separately been extended with constraints, to the streaming domain, and with capabilities to reason over the quantities associated with answer sets.

Reasoning on Multi-Relational Contextual Hierarchies via Answer Set Programming with Algebraic Measures

no code implementations6 Aug 2021 Loris Bozzato, Thomas Eiter, Rafael Kiesel

In this paper, we overcome these limitations and present a generalization of CKR hierarchies to multiple contextual relations, along with their interpretation of defeasible axioms and preference.

ASP(AC): Answer Set Programming with Algebraic Constraints

no code implementations10 Aug 2020 Thomas Eiter, Rafael Kiesel

Using a novel combination of Weighted Logic and Here-and-There (HT) Logic, in which this dependence is based on intuitionistic grounds, we introduce Answer Set Programming with Algebraic Constraints (ASP(AC)), where rules may contain constraints that compare semiring values to weighted formula evaluations.
