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 Minimal Left and Right Insertion and Deletion
(Fénix Editora, 2012)
In this article we investigate the operations of insertion and deletion performed at the ends of a string. We show that using these operations in a P systems framework (which corresponds to using specific variants of ...

A Formal Framework for P Systems with Dynamic Structure
(Fénix Editora, 2012)
This article introduces a formalism/framework able to describe different variants of P systems having a dynamic structure. This framework can be useful for the definition of new variants of P systems with dynamic structure, ...

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 ...

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 ...

Semilinear Sets, Register Machines, and Integer Vector Addition (P) Systems
(Fénix, 2016)
In this paper we consider P systems working with multisets with integer multiplicities. We focus on a model in which rule applicability is not in uenced by the contents of the membrane. We show that this variant is ...
