The multimodal optimisation problem challenges the balance between diversity and convergence; which poses a great degree of challenge to traditional population-based intelligence optimisers. The whale optimisation algorithm has the limitation of easily falling into local optimum when facing multimodal optimisation. To address this problem; this paper proposes a whale optimisation algorithm with role labour division (WOA-RDL). In WOA-RDL; a multi-stage role division of labour mechanism is designed to divide the optimisation process into two stages of group hunting. In the first stage; the task allocation in the hunting process is considered as two types of search tasks: exploration and exploitation. The external environmental stimulus of the task and the internal response threshold of the individual were designed to allow individuals to switch between exploration and exploitation tasks flexibly. In the second stage; the distribution mechanism of different roles was designed to simulate the 'strong to weak' distribution rule for the distribution of results after the hunt. The elite roles are selected to further strengthen their capabilities or remain robust; while the inferior roles are predicted and eliminated to improve the overall optimisation of the population and reduce the risk of falling into a local optimum. The results of the optimisation experiments using multimodal; unimodal; CEC2017 combined functions and CEC2009 dynamic functions to validate the effectiveness of the algorithm.
