Abstract [en]

Graph grammars based on contextual hyperedge replacement (CHR)  extend the generative power of the well-known hyperedge replacement  (HR) grammars to an extent that makes them useful for practical  modeling. Recent work has shown that acyclicity is a key condition for  parsing CHR grammars efficiently. In this paper we show that acyclicity of CHR grammars is decidable  and that the generative power of  acyclic CHR grammars lies strictly between that of HR grammars and  unrestricted CHR grammars.
