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 Cell Division
(Fénix Editora, 2004)
In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { ...

Solving the Partition Problem by Using Tissue-like P Systems with Cell Division
(Fénix Editora, 2008)
Tissue-like P systems with cell division is a computing model in the framework of Membrane Computing that shares with the spiking neural P system model a similar biological inspiration. Namely, both models are based on ...

Counting Membrane Systems
(University of Bradford, Faculty of Engineering and Informatics, 2017)
A decision problem is one that has a yes/no answer, while a counting problem asks how many possible solutions exist associated with each instance. Every decision problem X has associated a counting problem, denoted by ...

Tissue P systems with cell division
(Agora University of Oradea, 2008)
In tissue P systems several cells (elementary membranes) communicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell–like) P systems with active membranes ...

The Relevance of the Environment on the Efficiency of Tissue P Systems
(Springer, 2013)
The efficiency of computational devices is usually expressed in terms of their capability to solve computationally hard problems in polynomial time. This paper focuses on tissue P systems, whose efficiency has been shown ...

Simulating Tritrophic Interactions by Means of P Systems
(IEEE, 2010)
P systems provide a high level computational modelling framework that combines the structural and dynamical aspects of ecosystems in a compressive and relevant way. The inherent randomness and uncertainty in biological ...

Membrane dissolution and division in P
(Springer, 2009)
Membrane systems with dividing and dissolving membranes are known to solve PSPACE problems in polynomial time. However, we give a P upperbound on an important restriction of such systems. In particular we examine systems ...

Minimal cooperation in polarizationless P systems with active membranes
(Fénix, 2016)
P systems with active membranes is a well developed framework in the eld of Membrane Computing. Using evolution, communication, dissolution and division rules, we know that some kinds of problems can be solved by those ...

A P–Lingua Based Simulator for Spiking Neural P Systems
(Springer, 2011)
The research within the field of Spiking Neural P systems (SN P systems, for short) is focusing mainly in the study of the computational completeness (they are equivalent in power to Turing machines) and computational ...
