摘要
为改进鲸鱼算法的B样条曲线拟合在自动配置节点向量时收敛速度慢、局部搜索能力弱等缺点,采用Sobol序列来初始化种群,采用二次插值法来优化气泡网的捕捉策略。最后,通过3个测试函数仿真与另外2种算法的实验数据对比,验证了改进算法具有更好的全局收敛性和较快的收敛速度。
In order to improve the B-spline fitting of the whale algorithm with slow convergence rate and weak local search ability when automatically configuring node vectors,Sobol sequence is used to initialize the population,and quadratic interpolation is used to optimize the capture strategy of the bubble net.Finally,through the comparison of the experimental data of three test functions and the other two algorithms,it is proved that the improved algorithm has better global convergence and faster convergence speed.
