- Abstract:
-
To increase the convergence speed and solution accuracy of the traditional firefly algorithm, in this paper, we propose a firefly optimization algorithm that utilizes elite opposition-based learning. Using an opposition-based learning strategy, we constructed an elite group and, in the interval of the elite group, we solved the opposite solutions of the ordinary groups. This strategy could increase group diversity and improve the convergence speed of the algorithm. To prevent the optimal individual from falling into the local optimum, which could cause stagnation of the whole group during the search process, we introduce a differential evolutionary mutation strategy. Finally, we propose an adaptive step size with a linear decrease to balance the development ability of the algorithm. Experimental results show that the proposed algorithm can increase convergence speed and accuracy.
