(Tissue) P Systems with Anti-Membranes
(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 membranes as objects and anti-membranes as the corresponding annihilation counterpart in P systems. ...

Variants of P Systems with Toxic Objects
(Fénix Editora, 2015)
Toxic objects have been introduced to avoid trap rules, especially in (purely) catalytic P systems. No toxic object is allowed to stay idle during a valid derivation in a P system with toxic objects. In this paper we ...

The Membrane Systems Language Class
(Fénix Editora, 2010)
The aim of this paper is to introduce the class of languages generated by the transitional model of membrane systems without cooperation and without additional ingredients. The fundamental nature of these basic systems ...

Forward and Backward Chaining with P Systems
(Fénix Editora, 2011)
On the one hand, one of the concepts which lies at the basis of membrane computing is the multiset rewriting rule. On the other hand, the paradigm of rules is profusely used in computer science for representing and dealing ...

Unfair P Systems
(Fenix Editora, 2017)
We introduce a novel kind of P systems in which the application of rules in each step is controlled by a function on the applicable multisets of rules. Some examples are given to exhibit the power of this general concept. ...

Input-Driven Tissue P Automata
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
We introduce several variants of input-driven tissue P automata where the rules to be applied only depend on the input symbol. Both strings and multisets are considered as input objects; the strings are either read from ...

Extended SNP Systems with States
(Fénix, 2016)
We consider (extended) spiking neural P systems with states, where the applicability of rules in a neuron not only depends on the presence of su ciently many spikes (yet in contrast to the standard de nition, no regular ...

Complexity of Simulating R Systems by P Systems
(Fénix, 2016)
We show multiple ways to simulate R systems by non-cooperative P systems with atomic control by promoters and/or inhibitors, or with matter-antimatter annihi- lation rules, with a slowdown by a factor of constant. The ...

Catalytic P Systems with Weak Priority of Catalytic Over Non-catalytic Rules
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2020)
Catalytic P systems are among the rst variants of membrane systems ever considered in this area. This variant of systems also features some prominent computational complexity questions, and in particularly the problem ...

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 ...
