To solve Multimodal optimization problems(MOPs), a Novel Quantum entanglement-inspired meta-heuristic framework(NMF-QE) is proposed. Its main inspirations are two concepts of quantum physics:quantum entanglement and quantum superposition. When given Proto-born particles(PBPs) of a population, these two concepts are mathematically developed to generate twin-born and combination-born particles, *** if any elite-born particles would be created by a local re-searching strategy. These three or four groups of particles come together as a whole search population of NMF-QE to realize exploration and exploitation of algorithms. To guarantee dynamical optimization capability of NMF-QE, the individual evolutionary mechanism of some existing meta-heuristics will be adopted to iteratively create PBPs. A selected meta-heuristic is coupled with NMF-QE to present its improved variant. Numerical results show that the proposed NMF-QE can effectively improve optimization performance of meta-heuristics on MOPs.

为增强藤壶配尾优化算法(barnacles mating optimizer,BMO)的全局探索性能和局部寻优精度,融合藤壶幼虫的沉降附着行为与正反向递减铸型策略提出一种改进藤壶配尾优化算法(improved BMO,IBMO)并将其用于求解高维连续优化问题。沉降附着行为模型受自然界藤壶幼虫随潮浮游、螺旋沉降的行为启发所构建,以增加种群多样性并改善算法的全局探索性能。正反向递减铸型策略借鉴反向学习思想并融入递减调控机制修正传统藤壶优化算法的精子铸型过程,以扩增种群的局部搜索域并改善算法的局部开采性能。实验结果表明,两种策略可分别有效改善藤壶优化算法的全局探索和局部开采性能;同时,所提IBMO算法相较于其他新近智能算法则表现出更高收敛精度、更强算法稳健性和良好高维适用性等。
