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 ...

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. ...

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 ...

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 ...

Introducing the Concept of Activation and Blocking of Rules in the General Framework for Regulated Rewriting in Sequential Grammars
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
We introduce new possibilities to control the application of rules based on the preceding application of rules which can be de ned for a general model of sequential grammars and we show some similarities to other control ...

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 ...

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 ...

(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. ...
Presentation

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. ...

Playing with Derivation Modes and Halting Conditions
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
In the area of P systems, besides the standard maximally parallel derivation mode, many other derivation modes have been investigated, too. In this paper, many variants of hierarchical P systems and tissue P systems using ...
