【摘 要】本文针对传统积分方法,要求被积函数的有较强性质并且求解精度低的不足,提出了一种基于改进型人工萤火虫群优化算法求数值积分的新方法。该方法首先在积分区间上随机产生积分节点,然后通过改进型人工萤火虫群优化算法优化节点位置,再累积求和,得出数值积分。实验仿真表明,与其他方法相比,具有收敛速度快、精确度高等优点。

【Abstract】This paper proposes a new method of numerical integration based on a modified glowworm swarm optimization algorithm. Firstly, this method randomly generates integral nodes in the integration interval; next to optimize the nodes positions through the modified glowworm swarm optimization algorithm, thento sum cumulatively, the integral approximation can be obtained. The simulation shows that, compared with other methods, the modified glowworm swarm optimization algorithmhas obvious advantages in the accurate degree.
