Title: | A modified shuffled frog leaping algorithm for the topology optimization of electromagnet devices | Authors: | Yang, W Ho, SL Fu, W |
Issue Date: | 2020 | Source: | Applied sciences, 2020, v. 10, no. 18, 6186, p. 1-11 | Abstract: | The memetic algorithms which employ population information spreading mechanism have shown great potentials in solving complex three-dimensional black-box problems. In this paper, a newly developed memetic meta-heuristic optimization method, known as shuffled frog leaping algorithm (SFLA), is modified and applied to topology optimization of electromagnetic problems. Compared to the conventional SFLA, the proposed algorithm has an extra local search step, which allows it to escape from the local optimum, and hence avoid the problem of premature convergence to continue its search for more accurate results. To validate the performance of the proposed method, it was applied to solving the topology optimization of an interior permanent magnet motor. Two other EAs, namely the conventional SFLA and local-search genetic algorithm, were applied to study the same problem and their performances were compared with that of the proposed algorithm. The results indicate that the proposed algorithm has the best trade-off between the results of objective values and optimization time, and hence is more efficient in topology optimization of electromagnetic devices. | Keywords: | Evolutionary algorithm Numerical method Shuffled frog leaping algorithm Topology optimization |
