Weak Metrics on Configurations of a P System [Presentation]
(Fénix Editora, 2004)
The evolution of a P system generates a tree of computation po- tentially in¯nite where it is very difficult to set the degree of closeness between two configurations. The problem is specially hard if we want to quantify ...
Minimal Cooperation in P Systems with Symport/Antiport: A Complexity Approach [Presentation]
(Fénix Editora, 2015)
Membrane systems with symport/antiport rules compute by just moving objects among membranes, and not by changing the objects themselves. In these systems the environment plays an active role because, not only it receives ...
A Formal Framework for P Systems with Dynamic Structure [Presentation]
(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, ...
Cell-like Versus Tissue-like P Systems by Means of Sevilla Carpets [Presentation]
(Fénix Editora, 2009)
Sevilla Carpets are a handy tool for comparing computations performed by different systems solving the same problem. Such Sevilla Carpets provide on one hand quantitative information through parameters such as Weight, ...
A syntax for semantics in P-Lingua [Presentation]
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
P-Lingua is a software framework for Membrane Computing, it includes a programming language, also called P-Lingua, for writting P system de nitions using a syntax close to standard scienti c notation. The rst line of a ...
Revisiting Sevilla Carpets: A New Tool for the P-Lingua Era [Presentation]
(Fénix Editora, 2014)
Sevilla Carpets have already been used to compare di erent solutions of the Subset Sum problem: either designed in the framework of P systems with active membranes (both in the case of membrane division and membrane ...
