Abstract:

It is the best choice for intelligent algorithms to be applied to specific fields to explore strong searching ability, good reliability and stability.In this paper, aiming at the defects of chameleon swarm algorithm, such as unstable solution, low convergence accuracy and unbalanced search and development, a chameleon swarm algorithm (RMSCSA) based on population diversity segmental mutation learning and S-type weight is proposed. The refraction mirror learning strategy (RML) is introduced to make the chameleon more consistent with the observation in nature and enhance its diversity. The introduction of segmental variation of population diversity can keep the individuals with poor fitness and guide them to the optimal position. The introduction of S-type decreasing weight makes it further balance the global search and explore ability of the algorithm, and obtains the advantage of S-type decreasing weight factor through convergence analysis. The classical test function and CEC 2017 competition function are used for performance verification, and the results show that the three strategies have better optimization accuracy and efficiency for CSA. In order to compare the performance of different algorithms, the results of 30 independent runs are statistically analyzed by Wilcoxon rank-sum test, Friedman's test and Holm follow-up test. The analysis shows that the three strategies introduced have better optimization ability compared with CSA.
