基于探索与开发权衡的地磁仿生导航搜索方法

针对地磁仿生导航过程中对搜索偏向性考虑不足的问题,提出了一种基于探索与开发权衡的导航方法。依据时序进化搜索策略的结构特征,从统计学角度建立了磁趋势性运动模型,分析了探索与开发和磁趋势性运动的关系,并将搜索偏向权衡问题归结为对种群多样性的合理调控,引入分布熵的概念度量种群多样性,设计了分布熵约束下的磁趋势性搜索策略,给出了导航搜索流程。通过仿真分析,给出较为合理的参数设置,并将该方法与时序进化搜索方法进行对比实验,结果证实了所提方法能够有效提高导航效率。

Geomagnetic bio-inspired navigation based on balancing exploration and exploitation

A navigation method based on balancing exploration and exploitation is proposed for the issue of insufficient consideration of search bias in the geomagnetic bio inspired navigation process. Firstly, according to the structure feature of the sequence evolution search strategy, a magnetotaxis movement model is established based on statistical. Then, the relationship between the exploration exploitation and the magnetotaxis movement is analyzed, the problem of balancing searching bias is generalized as the reasonable control of population diversity. The concept of distribution entropy is introduced to measure the population diversity, and a new strategy for magnetotaxis search under the constraints of distribution entropy is designed. The navigation search procedure is given. Finally, through the simulation analysis, the reasonable parameter set is given, and comparing the proposed method with the sequence evolution search strategy, the simulation results show the effectiveness of the proposed approach.
