Abstract
Aiming at the shortcomings of spotted hyena optimizer, such as slow convergence speed, low searching accuracy and easy to fall into local optimal, this paper proposes an improved spotted hyena optimization algorithm (OWSHO) integrating multiple strategies. The reverse population is constructed by using the Opposition-Based Learning strategy to increase the diversity of the population and further improve the convergence speed of the algorithm. At the same time, the spiral exploration mechanism of whale optimization algorithm is combined to enhance the ability of exploring unknown regions and improve the global search performance of the algorithm. Then adaptive weight strategy is introduced to balance and improve the global exploration and local development ability of the algorithm. In this paper, 8 benchmark functions of CEC test set are used for simulation experiments, and compared with 3 heuristic algorithms, the test results show that: The improved spotted hyena optimization algorithm based on the combination of reverse learning, spiral exploration mechanism and adaptive weight strategy has a great improvement in the search accuracy and convergence speed, and gets rid of the local optimal to a certain extent, which proves the effectiveness and advancement of the algorithm.
