基于队长策略捕鱼算法的改进及性能测试

Improvement and performance test of fishing algorithmbased on captain strategy

针对传统捕鱼算法缺少信息共享机制、未充分利用群体优势的问题,提出基于信息共享的队长策略.通过队长对劣势群体的吸引策略,提升算法的收敛速度,同时保留较优群体的独立搜索机制,保障渔夫群体的多样性,以确保算法的全局收敛性.通过对6个典型函数进行测试,在参数设置相同的条件下,基于队长策略捕鱼算法在确保全局收敛的前提下,能明显提高寻优速率、稳定性等寻优性能.

As traditional fishing algorithm lacks information sharing and does not enjoy grouping advantage,the writer of this paper proposes a captain strategy that has improved the convergence speed of the algorithm,while retaining independent search mechanism to ensure the diversity of fishermen groups and global convergence of the algorithm.Through test of six typical functions under the same parameter settings,the writer finds the strategy significantly improves optimization rate,stability and other performances。
