The next steps of the algorithm apply to parameters of the entire swarm, not the individual particles. Consider the smallest f = min(f(j)) among the particles j in the swarm. If f < b, then set b = f and d = x. This step ensures b has the best objective function in the swarm...

particleswarm reached the value 0.000000 using 25191 function evaluations. disp(output.hybridflag) 1 While the hybrid function improved the result, the plot function shows the same final value as before. This is because the plot function shows only the particle swarm algorithm iterations, and not ...

group’s (or flock’s, or swarm’s) best overall position. This algorithm has been shown to have GA like advantages without the big computational hit. The PSO algorithm is based on the concept that complex behavior follows from a few simple rules [5]. The intricacies of the algori...
The team from Xi'an Satellite Control Center used the hybrid particle swarm optimization algorithm to solve this problem by combining particle swarm optimization with Fmincon (a nonlinear programming function of MATLAB). Firstly, this team used the hybrid particle swarm optimization algorithm to search...
