Abstract
We investigate the computational power of generalized P-systems of specific types in comparison with the computational power of certain control mechanisms for string rewriting grammars.An important restriction dwells in using sets of operators instead of multisets within sequential P-systems; this restriction is shown to be substantial, i.e., sequential P-systems of specific type using multisets are more powerful than the corresponding sequential P-systems using only sets.
