To improve particle swarm optimization (PSO) computing performance, the centroid of particle swarm is firstly introduced in standard PSO model to enhance interparticle cooperation and information sharing capabilities, then combining randomness and ergodicity of the strong chaotic motion and fast convergence of the simplex method, a novel particle swarm optimization algorithm with adaptive space...

blind source separation technique separates mixed signals blindly without any information on the mixing system. in this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. in these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. in order to evalu...

Particle swarm optimization (PSO) is a population-based swarm intelligence algorithm that shares many similarities with evolutionary computation techniques. However, the PSO is driven by the simulation of a social psychological metaphor motivated by collective behaviors of bird and other social organisms instead of the survival of the fittest individual. Inspired by the classical PSO method and...

Cloud workflow system is a kind of platform service based on cloud computing. It facilitates the automation of workflow applications. Between cloud workflow system and its counterparts, market-oriented business model is one of the most prominent factors. The optimization of task-level scheduling in cloud workflow system is a hot topic. As the scheduling is a NP problem, Ant Colony Optimization ...

Brain storm optimization (BSO) and particle swarm (PSO) are two popular nature-inspired algorithms, with BSO being the more recently developed one. It has been observed that an advantage over PSO regarding exploration a random initialization, while is capable at local exploitation if given predetermined initialization. The algorithms have also examined as hybrid. In this work, algorithm was hyb...

Radar signal sorting is the core part of electronic support measures, which responsible for deinterleaving overlapping pulse sequences received by receiver from complex environment, separating different radiation source signals, and providing identification. Particle swarm optimization (PSO) a population-based global algorithm with great advantages in intelligent can adapt to electromagnetic en...
