Effective optimization algorithm for multimodal functions

This paper proposed a novel niche technique to solve the problem of parameters' selection.Any parameters were unnecessary in this method.Through monitoring the changes of tangent value,particles were judged whether there were in the same hill and they would follow the best particle which was in the same hill with them.Each local best solution could be found in this way.The algorithm is easy to realize.So it not only can conquer the shortcoming the limitation of parameters but also only one solution can be found in particle swarm optimization algorithm.The typical numerical simulation results show that the improved algorithm is fairly effective.
