Simulation of Spiking Neural P Systems with Sparse Matrix-Vector Operations
(MDPI, 2021)
To date, parallel simulation algorithms for spiking neural P (SNP) systems are based on a matrix representation. This way, the simulation is implemented with linear algebra operations, which can be easily parallelized ...

A Study of Multiobjective Metaheuristics When Solving Parameter Scalable Problems
(IEEE Computer Society, 2010)
To evaluate the search capabilities of a multiobjective algorithm, the usual approach is to choose a benchmark of known problems, to perform a fixed number of function evaluations, and to apply a set of quality indicators. ...

From SAT to SAT-UNSAT using P systems with dissolution rules
(Springer, 2022)
DP is the class of problems that are the differences between two languages from NP. Most difficult problems from DP are called DP-complete problems, that can be seen as the conjunction of an NP-complete problem and a ...

Spiking Neural P systems with weights
(MIT Press, 2010)
A variant of spiking neural P systems with positive or negative weights on synapses is introduced, where the rules of a neuron fire when the potential of that neuron equals a given value. The involved values—weights, firing ...

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 Fine Grain Sentiment Analysis with Semantics in Tweets
(Universidad Internacional de La Rioja (UNIR), 2016)
Social networking is nowadays a major source of new information in the world. Microblogging sites like Twitter have millions of active users (320 million active users on Twitter on the 30th September 2015) who share ...

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 ...

The Spanish Network on Biomolecular and Biocellular Computing: Bio-inspired Natural Computing in Spain
(ERCIM EEIG, 2011-04)
The Spanish Network on Biomolecular and Biocellular Computing (Redbiocom) is a consortium of seven Spanish research groups whose research activities focus on the bio-inspired approach to Natural Computing. The Network was ...

A polynomial alternative to unbounded environment for tissue P systems with cell division
(Taylor and Francis, 2013)
The standard definition of tissue P systems includes a special alphabet whose elements are assumed to appear in the initial configuration of the system in an arbitrarily large number of copies. These objects reside in ...

Multiple Sequence Alignment with Multiobjective Metaheuristics. A Comparative Study
(Wiley, 2017)
Multiple sequence alignment (MSA) plays a core role in most bioinformatics studies and provides a framework for the analysis of evolution in biological systems. The MSA problem consists in finding an optimal alignment ...
