The convergence curve of fitness function of the proposed algorithm under different population size. The population size of the left subgraph is 30, and the right one is 60. (a) The convergence curve of fitness function of img2 with 9 thersholds. (b) The convergence curve of fitness function of img5 with 7 thersholds. (c) The convergence curve of fitness function of img8 with 5 thersholds.
