Meanwhile, the experiments show that the multi-level swarm intelligence refinement algorithm is better than the multi-level tabu search refinement algorithm, especially in view of the probability that the approximate global minimum partition of the coarser graph may be the local minimum partition of the finer graph. Furthermore, the experiments show that the multi-level ant colony optimization refinement algorithm achieves more performance improvement than the multi-level particle swarm optimization refinement algorithm, using the gain of vertex more effectively.
