Abstract

Here we continue the study of bio-Turing machines introduced in [2] and further investigated in [17]. We introduce a restricted model of bio-Turing machine and we investigate its computational power, a hierarchy of languages accepted, and deterministic and nondeterministic variants. A comprehensive example illustrating the modelling power of the introduced machine ends the paper.
