The used benchmark set included a domain describing the undecidable Post Correspondence Problem (PCP). In this paper we describe the two-step process applied to generate HTN problems based on PCP instances. It translates the PCP into a grammar intersection problem of two context-free languages, which is then encoded into an HTN problem.},
