In this paper we consider different regulation mechanisms imposed upon uniformly k-limited ETOL systems. We investigate matrix, periodically time varying, graphcontrolled, programmed and regularly controlled systems on the one side and random context and random context with appearance checking systems on the other side, as well as mixtures of these two types. For k = 1, we compare these systems with regulated context-free grammars as considered in the literature before. We establish equivalences between different such systems and grammars.

Regulations of Uniformly k-Limited ET0L Systems and Their Relations to Controlled Context-Free Grammars
