Solving Multi-Configuration Problems: A Performance Analysis with Choco Solver
Benjamin Ritz, Alexander Felfernig, Viet-Man Le +1
In many scenarios, configurators support the configuration of a solution that satisfies the preferences of a single user. The concept of \emph{multi-configuration} is based on the…
FastDiagP: An Algorithm for Parallelized Direct Diagnosis
Viet-Man Le, Cristian Vidal Silva, Alexander Felfernig +3
Constraint-based applications attempt to identify a solution that meets all defined user requirements. If the requirements are inconsistent with the underlying constraint set, algo…
Conjunctive Query Based Constraint Solving For Feature Model Configuration
Alexander Felfernig, Viet-Man Le, Sebastian Lubos
Feature model configuration can be supported on the basis of various types of reasoning approaches. Examples thereof are SAT solving, constraint solving, and answer set programming…
Configuring Multiple Instances with Multi-Configuration
Alexander Felfernig, Andrei Popescu, Mathias Uta +5
Configuration is a successful application area of Artificial Intelligence. In the majority of the cases, configuration systems focus on configuring one solution (configuration) tha…
CoreDiag: Eliminating Redundancy in Constraint Sets
Alexander Felfernig, Christoph Zehentner, Paul Blazek
Constraint-based environments such as configuration systems, recommender systems, and scheduling systems support users in different decision making scenarios. These environments ex…
Anytime Diagnosis for Reconfiguration
Alexander Felfernig, Rouven Walter, Jose A. Galindo +4
Many domains require scalable algorithms that help to determine diagnoses efficiently and often within predefined time limits. Anytime diagnosis is able to determine solutions in s…
An Efficient Diagnosis Algorithm for Inconsistent Constraint Sets
Alexander Felfernig, Monika Schubert, Christoph Zehentner
Constraint sets can become inconsistent in different contexts. For example, during a configuration session the set of customer requirements can become inconsistent with the configu…
Consistency-based Merging of Variability Models
Mathias Uta, Alexander Felfernig, Gottfried Schenner +1
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 accoun…
