Decision Tree Models Induced by Membrane Systems
(Romanian Academy, Section for Information Science and Technology, 2015)
This paper focuses on an application of membrane systems to solve classification problems. Decision tree technique has been widely used to construct classification models because such models can closely resemble ...

A fast P system for finding a balanced 2-partition
(Springer, 2005)
Numerical problems are not very frequently addressed in the P systems literature. In this paper we present an effective solution to the 2-Partition problem via a family of deterministic P systems with active membranes ...

The Factorization Problem: A New Approach Through Membrane Systems
(University of Paris Est Creteil Val de Marne, 2018)
The factorization problem (given a natural number which is the product of two prime numbers, find its decomposition) is conjectured to be intractable and for that it has been used as the key to have secure current ...

On P Systems with Bounded Parallelism
(IEEE Computer Society, 2005)
A framework that describes the evolution of P systems with bounded parallelism is de ned by introducing basic formal features that can be then integrated into a structural operational semantics. This approach investigates ...

Cell-like Versus Tissue-like P Systems by Means of Sevilla Carpets
(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 Model of the Quorum Sensing System in Vibrio fischeri Using P Systems
(MIT Press, 2008)
Quorum sensing is a cell density dependent gene regulation system that allows an entire population of bacterial cells to communicate in order to regulate the expression of certain or specific genes in a coordinated way ...

Dynamic threshold neural P systems
(Elsevier, 2019)
Pulse coupled neural networks (PCNN, for short) are models abstracting the synchronization behavior observed experimentally for the cortical neurons in the visual cortex of a cat’s brain, and the intersecting cortical ...

Formal Verification of P Systems with Active Membranes through Model Checking
(Springer, 2011)
Formal verification of P systems using model checking has attracted a significant amount of research in recent years. However, up to now only P systems with static structure have been considered. This paper makes ...

An infinite hierarchy of languages defined by dP systems
(Elsevier, 2012)
Here, we continue the study of the recently introduced dP automata. They are symport/antiport P systems consisting of a number of components, each one accepting a string, and working together in recognizing the concatenation ...
