Abstract: Abstract: To promote optimization performance of Harris hawks optimization algorithm, KmHHO algorithm is proposed. Firstly, all populations as a cluster, the cluster centroid is calculated with Kmeans of Matlab, mean of HHO is replaced by cluster centroid. Then, to control the segments of exploration and development, linearly decreasing escape energy of prey is replaced with exponentially decreasing escape energy of prey. Finally, searching performance of five algorithms is compared on 23 benchmark functions, the improved effect of KmHHO is verified and Wilcoxon rank sum test is utilized to analyze the difference of KmHHO with other four optimization algorithms. The experimental results show that among the 23 benchmarks, KmHHO can achieve the optimal value on 14 benchmark functions, and its overall performance is higher than GWO, HHO and AO, but it’s equivalent to DAHHO.
