Simulating FAS-induced apoptosis by using P systems
(Taylor and Francis Online, 2007)
In contrast to differential equations, P systems are an unconven- tional model of computation which takes into consideration the discrete character of the quantity of components and the inherent randomness that exists ...

How to express tumours using membrane systems
(ELSEVIER SCIENCE INC, 2007)
In this paper we discuss the potential usefulness of membrane systems as tools for modelling tumours. The approach is followed both from a macroscopic and a microscopic point of view. In the first case, one considers the ...

Cellular solutions to some numerical NP-complete problems: A prolog implementation
(Idea Group Inc., 2005)
This chapter is devoted to the study of numerical NP-complete problems in the framework of cellular systems with membranes, also called P systems (Pǎun, 1998). The chapter presents efficient solutions to the subset sum and ...

Multidimensional descriptional complexity of P systems
(Univ. degli Studi di Milano, 2005)
Membrane Computing is a branch of Natural Computing which starts from the assumption that the processes taking place in the compartmental structure of a living cell can be interpreted as computations. The description of ...

Local Search with P Systems
(IGI GLOBAL, 2011)
Local search is currently one of the most used methods for finding solutions in real-life problems. It is usually considered when the research is interested in the final solution of the problem instead of the how the ...

On a partial affirmative answer for a Paun's Conjecture
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2011)
At the beginning of 2005, Gheorghe Pun formulated a conjecture stating that in the framework of recognizer P systems with active membranes (evolution rules, communication rules, dissolution rules and division rules for ...

An approach to Ballistic deposition based on membrane computing
(Old City Publishing, Inc., 2009)
Ballistic Deposition was proposed by Vold [10] and Sutherland [9] as a model for colloidal aggregation. These early works were later extended to simulate the process of vapour deposition. In general, Ballistic Deposition ...

A Linear Time Solution to the Partition Problem in a Cellular Tissue-Like Model
(AMER SCIENTIFIC PUBLISHERS, 2010)
Tissue-like P systems with cell division is a computing model in the framework of membrane computing that is based on the intercellular communication and cooperation between neurons. In such a model, the structure of the ...

Characterizing tractability by cell-like membrane systems
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2006)
In this paper we present a polynomial complexity class in the framework of membrane computing. In this context, and using accepting transition P systems, we provide a characterization of the standard computational class P ...

P Systems with Membrane Creation and Rule Input
(Fénix Editora, 2005)
When a uniform family of recognizer P systems is designed to solve a problem, the data of a concrete instance of the problem is usually provided via a multiset which is placed in the so-called input membrane. In this paper ...
