In order to improve the precision of the result and keep the highly search performance, a parameter turning based on fitness variance of cuckoo search (VCS) algorithm is proposed, which analyzes the relationship between the fitness variance and the different parameters pa and β. This improves algorithm on the basis of fitness variance to adjust the parameters of algorithm dynamically. It uses CS and VCS to carry out numerical experiments for 5 test benchmarks. The simulation results show that the proposed VBA is superior to CS.
