Original Abstract

This paper investigates the reduction of scattered context grammars with respect to the number of non-context-free productions.  It proves that every recursively enumerable language is generated by a scattered context grammar that has no more than one non-context-free production. An open problem is formulated.

Keywords

Scattered context grammars, size reduction, the number of non-context-free productions, parallel productions, computational completeness, descriptional complexity
