Abstract
According to the particle swarm optimization algorithm (PSO) exist precocious and local convergence problem, Put forward a kind of improved particle swarm optimization algorithm, the gradient descent method (BP algorithm) as a particle swarm operator embedded in particle swarm algorithm, By static function approximation to test of the improvement of the particle swarm optimization algorithm, results show that the improved algorithm not only increased global optimization ability, but also avoid the immature convergence problem.
