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 ...

On the degree of parallelism in membrane systems
(Elsevier, 2007)
In the literature, several designs of P systems might be found for performing the same task. The use of different techniques or even different P system models makes it very difficult to compare these designs. In this ...

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 ...

A P-Lingua based Simulator for Tissue P Systems with Cell Separation
(Romanian Academy, Section for Information Science and Technology, 2014)
Tissue P systems are one of the currently active research topics within the field of Membrane Computing. In particular, their computational efficiency is being investigated in the case when the number of cells can grow ...

On the efficiency of cell-like and tissue-like recognizing membrane systems
(Wiley, 2009)
Cell-like recognizing membrane systems are computational devices in the framework of membrane computing inspired from the structure of living cells, where biological membranes are arranged hierarchically. In this paper ...

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 ...

Available Membrane Computing Software
(Springer, 2006)
The simulation of a P system with current computers is a quite com-plex task. P systems are intrinsically nondeterministic computational devices and therefore their computation trees are di±cult to store and handle with ...

A linear-time tissue P system based solution for the 3-coloring problem
(Elsevier, 2007)
In the literature, several examples of the efficiency of cell-like P systems regarding the solution of NPcomplete problems in polynomial time can be found (obviously, trading space for time). Recently, different new ...

Membrane fission versus cell division: When membrane proliferation is not enough
(Elsevier, 2015)
Cell division is a process that produces two or more cells from one cell by replicating the original chromosomes so that each daughter cell gets a copy of them. Membrane fission is a process by which a biological membrane ...

Multiobjective fuzzy clustering approach based on tissue-like membrane systems
(Elsevier, 2017-06)
Fuzzy clustering problem is usually posed as an optimization problem. However, the existing researchhas shown that clustering technique that optimizes a single cluster validity index may not provide satisfactory results ...
