摘要
En 中文
In the application of metaheuristic algorithms (MAs) to complicated optimization problem solving, it is significant to balance the exploitation and exploration to obtain a good near-optimum solution to the problem. Therefore, in this study, to balance the exploitative and explorative features of conventional MAs, a multi-strategy improved slime mould algorithm called MSMA is introduced. In MSMA, a new search equation is developed to achieve a tradeoff between exploitation and exploration. Then the dynamic random search technique is utilized as a local search engine to enhance the search efficiency of the algorithm. Finally, the adaptive mutation probability is designed to avoid premature convergence. MSMA is evaluated using 28 benchmark functions and several practical engineering issues such as welded beam design, pressure vessel design, tension/compression spring design, and UAV path planning. The simulation results based on 30 independent runs demonstrate that it is more efficient and robust than other state-of-the-art techniques from the literature according to the selected performance metrics such as mean values and standard deviations. The source code of MSMA is publicly available at https://github.com/denglingyun123/Multi-s trategy-improved-slime-mould-algorithm.(c) 2022 Elsevier B.V. All rights reserved.
