Abstract
We present a method of generating context-free languages, in a parallel way, using dynamic P systems, which evolve in time in a coherent manner. The evolution is described by a contextual grammar D(G), which can be canonically associated to any context-free grammar G. The dynamic P system generated by D(G) will “compute” the language L(G), i.e., one of the configurations of the system will contain all words of L(G) of length n at depth 2n - 1. Our approach is an attempt to prove the richness and power of the concept of dynamic P system, both in the area of P systems, and in the area of contextual grammars.
