Abstract: Generating plans in order to perform high-level tasks is difficult for agents that act in open-ended domains where it is unreasonable to assume that all necessary information is available a priori. This paper addresses this challenge by presenting a planning-based control system that is able to perform tasks in open-ended domains. The control system is based on a new HTN planning approach that additionally considers decompositions that would be applicable with respect to a consistent extension of the domain model at hand. The proposed control system constitutes a continual planning and acting system that interleaves planning and acting so that missing information can be acquired by means of active information gathering. Experimental results demonstrate that this control architecture can perform tasks in several domains even if the agent initially has no factual knowledge.
