A New Characterization of NP, P, and PSPACE with Accepting Hybrid Networks of Evolutionary Processors
(Springer, 2010)
We consider three complexity classes defined on Accepting Hybrid Networks of Evolutionary Processors (AHNEP) and compare them with the classical complexity classes defined on the standard computing model of Turing machine. ...

Laser Dynamics from a Membrane Computing Perspective
(IMCS. International Membrane Computational Society, 2018)
Modelling real systems and processes is a task classically performed through the approach of di erential equation systems, de ning the evolution of di erent variables as the di erent components of the system. A bad feature ...

Sorting Omega Networks Simulated with P Systems: Optimal Data Layouts
(Fénix Editora, 2008)
The paper introduces some sorting networks and their simulation with P systems, in which each processor/membrane can hold more than one piece of data, and perform operations on them internally. Several data layouts are ...

Uniform solutions to SAT and Subset Sum by spiking neural P systems
(Springer, 2009)
We continue the investigations concerning the possibility of using spiking neural P systems as a framework for solving computationally hard problems, addressing two problems which were already recently considered in this ...

Limits on Efficient Computation in P Systems with Symport/Antiport Rules
(Fenix Editora, 2017)
Classical membrane systems with symport/antiport rules observe the con- servation law, in the sense that they compute by changing the places of objects with respect to the membranes, and not by changing the objects ...

Fuzzy reasoning spiking neural P system for fault diagnosis
(Elsevier, 2013)
Spiking neural P systems (SN P systems) have been well established as a novel class of distributed parallel computing models. Some features that SN P systems possess are attractive to fault diagnosis. However, handling ...

Computing Partial Recursive Functions by Transition P Systems
(Springer, 2004)
In this paper a variant of transition P systems with external output designed to compute partial functions on natural numbers is presented. These P systems are stable under composition, iteration and unbounded minimization ...

MeCoSim: A general purpose software tool for simulating biological phenomena by means of P Systems
(IEEE Computer Society, 2010)
In recent years, the increasing importance of the computational systems biology is leading to an impressive growth of the knowledge of several real-life phenomena. In this framework, membrane computing is an emergent ...

Spiking neural P systems with extended rules: universality and languages
(Springer, 2008)
We consider spiking neural P systems with rules allowed to introduce zero, one, or more spikes at the same time. The motivation comes both from constructing small universal systems and from generating strings; previous ...

Decision Tree Models Induced by Membrane Systems
(Romanian Academy, Section for Information Science and Technology, 2015)
This paper focuses on an application of membrane systems to solve classification problems. Decision tree technique has been widely used to construct classification models because such models can closely resemble ...
