- Abstract:
-
In a normal PSO algorithm, particle populations are usually produced randomly, leading to variations in search quality and speed. Such algorithms cannot be used to solve engineering problems that must be optimized quickly. In order to solve such problems, a PSO algorithm based on uniform design was used to generate initial PSO populations. This made the distribution of particles more uniform in the search space. Four methods for generation of particle swarms were studied. Test results showed that search precision was considerably improved if the generation of a particle swarm by the uniform design method was based on value range division. That method maintained search efficiency and precision, stabilized search efficiency and precision, and reduced the possibility of swarm aggregation and premature convergence.
