Abstract

Scattered context grammars, introduced as a straightforward generalization of context-free grammars, apply n context-free productions in parallel to generate their sentences. This paper discusses their restricted versions in which all components of scattered context productions are either linear or right-linear. We prove that the families of languages generated by these grammars are equivalent to the families generated by linear and right-linear simple matrix grammars. Finally, we mention the generative power of scattered context grammars with context-sensitive and unrestricted productions and discuss some open problems.
