摘要
为解决频率分配问题,提出了一种基于蜜源优化的频率分配方法。首先提出了评估干扰程度的计算方法,对传统人工蜂群算法的引领蜂搜索行为进行改进,并重新设计跟随蜂搜索行为,增加选择性变异操作,以达到增加蜜源多样性以及降低陷入局部最优解可能性的目的。仿真结果表明,所提算法在搜索效率和稳定性上具有明显优势,能够在有效时间内找到满足频率距离约束的频率分配方案。
In order to solve the frequency assignment problem, a frequency assignment method based on the honey source optimization strategy is proposed. To increase the diversity of the honey and reduce the possi-bility of falling into the local optimal solution, a traditional artificial bee colony algorithm is improved. Firstly,a method to evaluate the interference is proposed. Secondly, the searching behave of leading bee is improved,and searching behave of following bee is redesigned. Finally, selective mutation operation is add-ed after the searching of reconnoitering bee. The simulation results show that the proposed algorithm has more advantages in searching efficiency and stability and can find frequency assignment strategy satisfying frequency-distance constraints with acceptable time consumption.
