| Abstract: |
| 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 possibility 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 added 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. |
