The final section of this work seeks to collect in one place several of the most important features of the Hunter-Gatherer control architecture. We begin by stating outright what we believe are the novel contributions made to the state of the art. We discuss the formal characteristics of HG, including the important notions of soundness and completeness. Finally, we point out some of the interesting aspects behind the success of HG. Included in this is a discussion on how HG implements island processing, and how the notion of graph topology can be used to explain the benefits (and limitations) of Hunter-Gatherer.
