A Formalization of Sequential, Parallel, and Continuous Rewriting
A formalization of the sequential, parallel, and continuous rewriting based on a uniform underlying concept of selective substitution grammars is presented. Each of the rewriting modes is formalized through a universal derivation restriction characterizing the rewriting in question. It is shown that whichever of the three rewriting modes is formalized, the resulting grammars generate precisely the family of context sensitive languages. Moreover, when erasing productions are allowed, these grammars generate all recursively enumerable languages.

V článku je předvedena formalizace sekvenčního, paralelního a průběžného přepisování založená na jednotném konceptu výběrových substitučních gramatik. Tyto gramatiky, pokud obsahují epsilon pravidla, generují třídu rekurzivně spočetných jazyků.
