Abstract

This contribution discusses the descriptional complexity of matrix grammars using left-most derivation of type two with respect to the number of nonterminals and matrices with two or more productions. It proves that these matrix grammars need only nine nonterminals and six matrices of length two or more to generate recursively enumerable languages.
