摘要
We settle here two problems concerning the generative power of parallel communicating grammar systems with right-linear components: (1) each linear language can be generated by a non-centralized returning system, (2) the family of languages generated by centralized returning systems is incomparable with the family of languages generated by non-returning centralized systems. It is also proved that centralized returning systems with right-linear components are strictly more powerful than systems with regular rules in the restricted sense.
