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 ...

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 ...

Narrowing Frontiers of Efficiency with Evolutional Communication Rules and Cell Separation
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
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 ...

Spiking neural P systems with inhibitory rules
(Elsevier, 2020)
Motivated by the mechanism of inhibitory synapses, a new kind of spiking neural P (SNP) system rules, called inhibitory rules, is introduced in this paper. Based on this, a new variant of SNP systems is proposed, called ...

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 ...

A Simulation Software Tool for Cell-like Spiking Neural P Systems
(Romanian Academy, Section for Information Science and Technology, 2017)
Spiking neural P systems (SN P systems, for short) constitute a class of computing models in the research eld of membrane computing. Inspired by the interactions among neurons in the brain, they have attracted much attention ...

A Semantic Frontier of the Efficiency in Membrane Systems
(Centre for Discrete Mathematics and Theoretical Computer Science, 2018)
The (presumed) efficiency of computing models is expressed by means of their ability to solve (NP-complete) presumably intractable problems in an efficient way or not. The relevance of this kind of frontier lies in the ...

When object production tunes the efficiency of membrane systems
(Elsevier, 2020)
Psystems with active membranes is one of the most studied models within the field ofMembrane Computing. Simulating the organization and behavior of the living cells througha tree-like structure and abstracting the mechanisms ...

Tuning Frontiers of Efficiency in Tissue P Systems with Evolutional Communication Rules
(Hindawi, 2021)
Over the last few years, a new methodology to address the P versus NP problem has been developed, based on searching for borderlines between the nonefficiency of computing models (only problems in class P can be solved ...
