Kurzfassung englisch:
Recently, liberally domain-expansion safe HEX-programs have been presented as a generalization of strongly safe HEX-programs that enlarges the scope of effective applicability. While such programs can be finitely grounded, a concrete grounding algorithm that is practically useful remained open. In this paper, we present such an algorithm and show how to integrate it into the model-building framework for HEX-programs, which is extended for this purpose. While traditional HEX-evaluation relies on program decomposition for grounding, our new algorithm can directly ground any liberally domain-expansion safe program without decomposition. However, as splitting is still sometimes useful for performance reasons, we develop a new decomposition heuristics that aims at maximizing efficiency. An experimental evaluation confirms the practicability of our approach.
