Abstract

This paper discusses context-free rewriting systems in which there exist two
disjoint finite sets of rules, and a symbol, referred to as a condition of
applicability, is attached to each rule in either of these two sets. In one set,
a rule with a symbol attached to it is applicable if the attached symbol occurs
in the current rewritten string while in the other set, such a rule is applicable
if the attached symbol does not occur there. The present paper demonstrates that
these rewriting systems are computationally complete. From this main result, the
paper derives several consequences and solves several open problems.
