In this paper, a hybrid metaheuristic based on Imperialist Competitive Algorithm (ICA) and on the Nelder-Mead simplex method (NM) is proposed. The purpose of NM is to improve both the diversification and the intensification capabilities of ICA. The proposed algorithm, called ICA-NM, is validated and compared with ICA and two other well-known metaheuristics using the benchmark of the CEC’2005 congress. The results show the efficiency of the proposed algorithm. Then, ICA-NM is used to design an optimal motor for an electric scooter in terms of both its mass and its output power. For this practical problem, ICA-NM outperforms several well-known metaheuristics used for this problem. Finally, the solution found by ICA-NM is validated by building and testing the corresponding prototype motor.
