A Tent chaos mapping is introduced to initialize thepopulation and increase the population diversity,and a dynamic transformation probability strategy is introduced to balance the weight ofglobal exploration?and local exploitation,so the Aquila algorithm with polynomial variance and adaptive weight optimization is proposed.The basic Aquila algorithm, Harris Hawks algorithm, Gray Wolf algorithm, Whale algorithm, and Seagull algorithm are used forcomparison,and 9 benchmark test functions and 2 engineering optimization problems are used to verify the improved algorithm ’ soptimization-seeking performance. The results show that the improved algorithm achieves better optimization-seeking results on most ofthe test functions and outperforms most of the comparison algorithms in engineering optimization problems. It is proved that the improvedalgorithm has faster convergence speed and accuracy,and achieves good results in engineering applications.
