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