Minimal cooperation as a way to achieve the efficiency in cell-like membrane systems
(Springer, 2019)
Cooperation is doubtless a relevant ingredient on rewriting rules based computing models. This paper provides an overview on both classical and newest results studying how cooperation among objects influences the ability ...

From Super-cells to Robotic Swarms: Two Decades of Evolution in the Simulation of P Systems
(IMCS: International Membrane Computing Society, 2017)
Membrane Computing provides machine-oriented models of computation, with types and variants including different elements inspired from living cells. Proven computationally complete from their inception, they also showed ...

P systems with evolutional symport and membrane creation rules solving QSAT
(Elsevier, 2022)
P systems are computing devices based on sets of rules that dictate how they work. While some of these rules can change the objects within the system, other rules can even change the own structure, like creation rules. ...

The Unique Satisfiability Problem from a Membrane Computing Perspective
(Romanian Academy, Section for Information Science and Technology, 2018)
Complexity class DP is the class of “differences” of any two languages in NP. It verifies that NP[ co-NP DP PNP, where PNP is the second level of the polynomial hierarchy, specifically, it is the class of languages ...

Polarizationless P Systems with Active Membranes: Computational Complexity Aspects
(Institut für Informatik, Justus-Liebig-Universität Giessen, 2016)
P systems with active membranes, in their classical definition, make use of noncooperative rules only. However, it is well known that in living cells, proteins interact among them yielding new products. Inspired by this ...

Tissue P systems with evolutional communication rules with two objects in the left-hand side
(Springer, 2022-10-19)
In the framework of Membrane Computing, several efficient solutions to computationally hard problems have been given. To find new borderlines between families of P systems that can solve them and the ones that cannot is ...

Cell-like P systems with evolutional symport/antiport rules and membrane creation
(Elsevier, 2020)
Cell-like P systems with symport/antiport rules are computing models inspired by theconservation law, in the sense that they compute by changing the places of objectswith respect to the membranes, and not by changing the ...
Artículo
From distribution to replication in cooperative systems with active membranes: A frontier of the efficiency
(Elsevier, 2018)
P systems with active membranes use evolution, communication, dissolution and division(or separation) rules. They do not use cooperation neither priorities, but they haveelectrical charges associated with membranes, which ...

P systems with evolutional communication and division rules
(MDPI, 2021)
A widely studied field in the framework of membrane computing is computational complexity theory. While some types of P systems are only capable of efficiently solving problems from the class P, adding one or more syntactic ...

P systems with symport/antiport rules: When do the surroundings matter?
(Elsevier, 2018-05-01)
Cell-like P systems where communication between the regions are carried out by rules of type symport/antiport are considered. These systems compute by changing the places of objects with respect to the membranes, and not ...
