The AHS-DE-OBL algorithm proposed in this study utilizes innovative strategies such as differential evolution, adaptive adjustment of search domain, and opposition-based learning to improve upon the limitations of the harmony search algorithm, resulting in better global search ability and faster convergence speed.
An adaptive harmony search algorithm utilizing differential evolution and opposition based learning (AHS-DE-OBL) is proposed to overcome the drawbacks of the harmony search (HS) algorithm, such as its low fine-tuning ability, slow convergence speed, and easily falling into a local optimum. In AHS-DE-OBL, three main innovative strategies are adopted. First, inspired by the differential evolution algorithm, the differential harmonies in the population are used to randomly perturb individuals to improve the fine-tuning ability. Then, the search domain is adaptively adjusted to accelerate the algorithm convergence. Finally, an opposition-based learning strategy is introduced to prevent the algorithm from falling into a local optimum. The experimental results show that the proposed algorithm has a better global search ability and faster convergence speed than other selected improved harmony search algorithms and selected metaheuristic approaches.
