New Choice for Small Universal Devices: Symport/Antiport P Systems

Sergey Verlan, Yurii Rogozhin
2009 Electronic Proceedings in Theoretical Computer Science  
Symport/antiport P systems provide a very simple machinery inspired by corresponding operations in the living cell.  ...  It turns out that systems of small descriptional complexity are needed to achieve the universality by these systems.  ...  Hence, deterministic P systems with minimal symport and antiport rules with any number of membranes can generate only finite languages.  ...

Implementing Bead-Sort with P Systems [chapter]

Joshua J. Arulanandham
2002 Lecture Notes in Computer Science  
Beads are represented by objects placed within membranes of a tissue P system; a rod is represented by a 'group' of membranes that can communicate with one another by means of symport/antiport rules.  ...  This natural sorting phenomenon is "implemented" with a special type of P system -a tissue P system that computes by means of communication (using symport/antiport rules) only.  ...  Beads are represented by objects x placed within the membranes; a rod is represented by a 'group' of membranes that can communicate with one another by means of symport/antiport rules.  ...

P Systems with Evolutional Communication and Division Rules

David Orellana-Martín, Luis Valencia-Cabrera, Mario J. Pérez-Jiménez
2021 Axioms  
This result is comparable to the one obtained in the tissue-like counterpart, and gives a glance of a parallelism and the non-evolutionary membrane systems with symport/antiport rules.  ...  In this work, a solution to the SAT problem, a well-known NP-complete problem, is obtained by means of a family of recognizer P systems with evolutional symport/antiport rules of length at most (2,1) and  ...  It is important to take into account that this is a great difference with P systems with active membranes, since in these systems, communication rules between membranes are limited to one object per membrane  ...
