摘　　要：针对基本正弦余弦算法在处理函数优化问题时优化精度低、易陷入局部最优、收敛速度慢等问题,提出一种螺旋更新的正弦余弦算法。首先,非线性调整参数,平衡全局勘探和局部开发能力;其次,利用螺旋更新策略,改进原算法搜索方式,提高优化精度,增强全局搜索能力,防止陷入局部最优;最后,采用贪婪选择与高斯变异策略,提高收敛速度和优化精度。采用23个基本测试函数进行仿真实验,并与其它几种算法进行比较,实验结果表明改进算法具有较高的优化性能。Aiming at the problems of basic sine cosine algorithm with low convergence accuracy,easy to fall into local optimality,and slow convergence speed when processing function optimization problems,a sine cosine algorithm for spiral update is proposed.First,non-linear adjustment of parameters to balance global exploration and local development abilities.Secondly,the spiral update strategy is used to improve the original algorithm search method,improve the optimization accuracy,enhance the global exploration ability,and prevent falling into local optimization.Finally,greedy selection and Gaussian mutation strategy are adopted to improve the convergence speed and the optimization accuracy.The simulation experiment is carried out by using 23 basic test functions and compared with several other algorithms,and the experimental results show that the improved algorithm had high optimization performance.
