摘    要:针对鸡群算法建立Markov链数学分析模型,分析此Markov链的一些性质,证明鸡群状态序列是有限齐次Markov链。结合随机算法收敛准则,证明鸡群算法能够满足随机算法全局收敛的2个准则,保证算法全局收敛。将算法应用于15个标准测试函数寻优问题,并同标准粒子群算法、蝙蝠算法进行比较。实验结果表明:该算法具有较好的全局收敛性和计算鲁棒性,尤其适合高维、多峰的复杂函数求解。

Abstract: The Markov chain model for chicken swarm optimization (CSO) was established, and the properties of the model were analyzed, which proved that chicken swarm state sequence was a finite homogeneous Markov chain. According to the convergence criteria of stochastic search algorithm, chicken swarm optimization was demonstrated to meet the two convergence criteria, so that the global convergence was ensured. Finally, 15 benchmark functions were used to test the CSO algorithm, and the comparison with particle swarm optimization (PSO) and bat algorithm (BA) was also performed. The simulation results show that CSO outperforms other algorithms in terms of global convergence and computational robustness, and it is particularly suitable for solving high-dimension and multimodal function optimization problems.
