Computational Completeness of P Systems Using Maximal Variants of the Set Derivation Mode
(Fénix, 2016)
We consider P systems only allowing rules to be used in at most one copy in each derivation step, especially the variant of the maximally parallel derivation mode where each rule may only be used at most once. Moreover, ...

Asynchronous and Maximally Parallel Deterministic Controlled Non-Cooperative P Systems Characterize NFIN coNFIN
(Fénix Editora, 2012)
Membrane systems (with symbol objects) are distributed controlled multiset processing systems. Non-cooperative P systems with either promoters or inhibitors (of weight not restricted to one) are known to be computationally ...

Extended Spiking Neural P Systems with White Hole Rules
(Fénix Editora, 2015)
We consider extended spiking neural P systems with the additional possibility of so-called \white hole rules", which send the complete contents of a neuron to other neurons, and we show how this extension of the original ...

One-Membrane P Systems with Activation and Blocking of Rules
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
We introduce new possibilities to control the application of rules based on the preceding applications, which can be de ned in a general way for (hierarchical) P systems and the main known derivation modes. Computational ...

The Power of Symport-3 with Few Extra Symbols
(Fénix Editora, 2012)
Membrane systems (with symbol objects) are formal models of distributed parallel multiset processing. Symport rules move multiple objects to a neighboring region. It is known that P systems with symport rules of weight ...

Length P Systems with a Lone Traveler
(Fénix Editora, 2014)
In this paper we consider P systems with linear membrane structures (only one membrane is elementary) with at most one object. We raise and attack the question about the computational power of such systems, depending on ...

P Systems with Limited Capacity
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2020)
P systems are a model of compartmentalized multiset rewriting inspired by the structure and functioning of the living cell. In this paper, we focus on a variant in P systems in which membranes have limited capacity, i.e., ...

Characterizing the Computational Power of Energy-Based P Systems
(Fénix Editora, 2012)
We investigate the computational power of energy-based P systems, a model of membrane systems where a fixed amount of energy is associated with each object and the rules transform single objects by adding or removing ...

Time-freeness and Clock-freeness and Related Concepts in P Systems
(Fenix Editora, 2017)
In the majority of models of P systems, rules are applied at the ticks of a global clock and their products are introduced into the system for the following step. In timed P systems, di erent integer durations are ...
