Monodirectional Tissue <i>P</i> Systems With Promoters

Tissue $P$ systems with promoters provide nondeterministic parallel bioinspired devices that evolve by the interchange of objects between regions, determined existence some special called . However, in cellular biology, movement molecules across a membrane is transported from high to low concentration. Inspired this biological fact, article, an interesting type tissue systems, monodirectional , where communication happens two regions only one direction, considered. Results show finite sets numbers are produced such cell, using any length symport rules or number cells, maximal 1 rules, and working maximally mode. Monodirectional Turing universal 2, at most promoter for each rule, mode three 1, flat We also prove rule (under certain restrictive conditions) characterizes regular natural numbers. Besides, computational efficiency analyzed when cell division incorporated. Different uniform solutions Boolean satisfiability problem (SAT problem) provided. These results condition “monodirectionality,” still computationally powerful. With powerful power, developing algorithms potentially exploitable.
