Original Abstract

The scattered context grammars are based on application of n context-free productions in parallel to generate their sentences. We can find two basic versions of this grammar type - erasing and propagating grammars. Erasing productions are allowed in erasing grammar, while they are prohibited in propagating grammars. In this paper, we present regulated versions of these grammars, where productions are regulated by the production-priority function. The priority function guarantees that productions will be applied whenever it is possible according to their priority. We also provide formal proofs of generative power of these grammars.
