Abstract: In order to overcome the disadvantages of particle swarm optimization algorithm such as premature, bad searching capability, a Modified Particle Swarm Optimization (MPSO) algorithm was proposed. In this algorithm, when particles fall into the local extreme area, the particles, which gathered at the global optimal particle of the swarm, would have a mutation. Then test results of six complex benchmark functions and computer color matching model indicate that MPSO is superior to other two classic PSOs, which has high convergence precision, fast convergence speed and prevents particle premature effectively.

Key words: particle swarm optimization, inertia weight, global exploration; premature, mutation
