Computation of Ramsey Numbers by P Systems with Active Membranes
(World Scientific, 2011)
Ramsey numbers deal with conditions when a combinatorial object necessarily contains some smaller given objects. It is well known that it is very difficult to obtain the values of Ramsey numbers. In this work, a theoretical ...

Simulating a P system based efficient solution to SAT by using GPUs
(Elsevier, 2010)
P systems are inherently parallel and non-deterministic theoretical computing devices defined inside the field of Membrane Computing. Many P system simulators have been presented in this area, but they are inefficient since ...

Small universal simple spiking neural P systems with weights
(Springer, 2014)
Spiking neural P systems with weights (WSN P systems, for short) are a new variant of spiking neural P systems, where the rules of a neuron are enabled when the potential of that neuron equals a given value. It is known ...

Modeling Logic Gene Networks by Means of Probabilistic Dynamic P Systems
(Old City Publishing, 2013)
Gene regulatory networks are useful models for biologists to understand the interactions among genes in living organisms. In this work, we consider a special class of gene regulatory networks, called logical networks, ...

Spiking Neural P systems with several types of spikes
(Agora University of Oradea, 2011)
With a motivation related to gene expression, where enzymes act in series, somewhat similar to the train spikes traveling along the axons of neurons, we consider an extension of spiking neural P systems, where several ...

Solving Common Algorithmic Problem by Recognizer Tissue P Systems
(Romanian Academy, 2012)
Common Algorithmic Problem is an optimization problem, which has the nice property that several other NP-complete problems can be reduced to it in linear time. In this work, we deal with its decision version in the ...

3-Col problem modelling using simple kernel P systems
(Taylor and Francis, 2013)
This paper presents the newly introduced class of (simple) kernel P systems ((s)kP systems) and investigates through a 3-colouring problem case study the expressive power and efficiency of kernel P systems. It describes ...

Comparing simulation algorithms for multienvironment probabilistic P systems over a standard virtual ecosystem
(Springer, 2012)
Membrane Computing has recently proved to be a suitable framework for addressing the modelling of dynamical biological systems in general, and ecosystems in particular. Due to the inherent randomness and uncertainty in ...

Improving GPU Simulations of Spiking Neural P Systems
(Romanian Academy, 2012)
In this work we present further extensions and improvements of a Spiking Neural P system (for short, SNP systems) simulator on graphics processing units (for short, GPUs). Using previous results on representing SNP system ...

A P-Lingua based simulator for Tissue P systems
(Elsevier, 2010)
Investigations within the field of tissue-like P systems are being conducted, on one hand studying their computational efficiency, and on the other hand exploring the possibilities to use them as a computational modelling ...
