Beyond Generalized Multiplicities: Register Machines over Groups
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
Register machines are a classic model of computing, often seen as a canonical example of a device manipulating natural numbers. In this paper, we de ne register machines operating on general groups instead. This ...

P Systems: from Anti-Matter to Anti-Rules
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
The concept of a matter object being annihilated when meeting its corresponding anti-matter object is taken over for rule labels as objects and anti-rule labels as the corresponding annihilation counterpart in P systems. ...

Purely Catalytic P Systems over Integers and Their Generative Power
(Fénix, 2016)
We further investigate the computing power of the recently introduced P systems with Z-multisets (also known as hybrid sets) as generative devices. These systems apply catalytic rules in the maximally parallel way, even ...

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 ...

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., ...

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 ...

P Systems with Randomized Right-hand Sides of Rules
(Fenix Editora, 2017)
P systems are a model of hierarchically compartmentalized multiset rewriting. We introduce a novel kind of P systems in which rules are dynamically constructed in each step by non-deterministic pairing of left-hand and ...
