混合生物地理优化策略

针对生物地理学优化算法全局搜索能力较弱,易于陷入局部最优解的缺点,提出了一种双向搜索的策略.在生物地理学优化算法中引入反转算子与正交实验设计的思想,以提高算法的收敛速度与全局搜索能力.通过对标准测试函数的实验,显示出新算法的高效性,并将其应用于调谐质量阻尼器参数优化问题.实验证明,该算法不但克服了原算法的缺陷,而且在精度和稳定性上也得到了显著提高.

Hybrid biogeography-based optimization strategy

In order to overcome poor searching ability and being prone to get a local best answer of the BBO ,a bi-directional searching strategy is proposed .An orthogonal design and inversion operator is in-troduced into iteration of BBO to improve the convergence rate and global search capability .Experiments have been conducted on high-dimensional benchmark function .And the results indicate the good per-formance of HBBO .Then the proposed algorithm is used to solve optimization of the required parame-ters of a tuned mass dampers system ,the results show that the algorithm succeed in overcoming the o-riginal defects and significantly improving its performance in accuracy and stability .
