Particle Swarm Optimization with Negative Gradient

Abstract:

Based on the standard particle swarm optimization, introduce the information about negative gradient to influence the update of velocities of the particles, proposed the particles swarm optimization with negative gradient , and make the movement of particles more pertinent. The result of computer simulation about several test functions indicates that the particle swarm optimization with negative gradient can improve optimization efficiency and get better results.
