Descriptional Complexity of Grammars Regulated by Context Conditions

This paper improves several well-known results concerning the descriptional complexity of grammars regulated by context conditions. Specifically, it proves that every recursively enumerable language is generated (A) by a context-conditional grammar of degree (2, 1) with no more than seven conditional productions and eight nonterminals, (B) by a generalized forbidding grammar of degree two with ...

Descriptional complexity of multi-parallel grammars

This paper studies the descriptional complexity of multi-parallel grammars with respect to the number of nonterminals and selectors, and the length of these selectors. As a result, it proves that every recursively enumerable language is generated by a multi-parallel grammar with no more than seven nonterminals and four selectors of length five.
