Using Symmetries to Lift Satisfiability Checking

no code implementations6 Nov 2023 Pierre Carbonnelle, Gottfried Schenner, Maurice Bruynooghe, Bart Bogaerts, Marc Denecker

Thus, we propose a 2-step novel method: (i) the sentence to be satisfied is automatically translated into an equisatisfiable sentence over a ``lifted'' vocabulary that allows domain compression; (ii) satisfiability of the lifted sentence is checked by growing the (initially unknown) compressed domain until a satisfying structure is found.

Applying Incremental Answer Set Solving to Product Configuration

no code implementations18 Jul 2022 Richard Comploi-Taupe, Giulia Francescutto, Gottfried Schenner

Using complex domain-specific configuration actions makes it possible to tightly control the level of non-determinism and performance of the solving process.

Consistency-based Merging of Variability Models

no code implementations15 Feb 2021 Mathias Uta, Alexander Felfernig, Gottfried Schenner, Johannes Spoecklberger

Globally operating enterprises selling large and complex products and services often have to deal with situations where variability models are locally developed to take into account the requirements of local markets.

OOASP: Connecting Object-oriented and Logic Programming

no code implementations12 Aug 2015 Andreas Falkner, Anna Ryabokon, Gottfried Schenner, Kostyantyn Shchekotykhin

Modeling phases -- during which software engineers analyze requirements to the future system using some modeling language -- are an important part of the development process, since modeling errors are often hard to recognize and correct.
