no code implementations19 Sep 2022 Richard Comploi-Taupe, Gerhard Friedrich, Konstantin Schekotihin, Antonius Weinzierl

Additionally, we use our approach to implement informed} search with A*, which is tackled within ASP for the first time.

Advancing Lazy-Grounding ASP Solving Techniques -- Restarts, Phase Saving, Heuristics, and More

no code implementations8 Aug 2020 Antonius Weinzierl, Richard Taupe, Gerhard Friedrich

Answer-Set Programming (ASP) is a powerful and expressive knowledge representation paradigm with a significant number of applications in logic-based AI.

Conflict Generalisation in ASP: Learning Correct and Effective Non-Ground Constraints

1 code implementation7 Aug 2020 Richard Taupe, Antonius Weinzierl, Gerhard Friedrich

We demonstrate the effects of our method by means of realistic examples, showing that our approach requires low computational cost to learn constraints that yield significant performance benefits in our test cases.

Degrees of Laziness in Grounding: Effects of Lazy-Grounding Strategies on ASP Solving

1 code implementation29 Mar 2019 Richard Taupe, Antonius Weinzierl, Gerhard Friedrich

Our contributions are the introduction of a range of novel lazy grounding strategies, a formal account on their relationships and their correctness, and an investigation of their effects on solving performance.
