Abstract

This paper demonstrates a uniform permutation-based generation of languages by using scattered context grammars.

Annotation

The present paper discusses the uniform generation of languages by scattered context grammars. More specifically, it demonstrates that every recursively enumerable language can be generated by a scattered context grammar, G, so that every sentential form in a generation of a sentence has the form y_1\ldots y_m i, where u is a terminal word and each y_i is a permutation either of two equally long words, z_1 \in \{A, B, C\}^* and z_2 \in \{ A, B, D\}^*, where A, B, C, and D are G's nonterminals. Then, it presents an analogical result so that u precedes y_1\ldots y_m.
