摘要
提出了利用人工鱼群算法求解二重数值积分的方法,将不等距离分割方法与人工鱼群算法相结合来求解数值积分同时在积分求和式子中引入一个参数。最后给出几个数值积分算例,并与其它数值积分方法作了比较,仿真结果分析表明,该方法具有更高阶的精度和更快的收敛速度。
A new method is presented to calculate two-dimensional numerical integration based on artificial fish-swarm algorithm.The method is based on inequality point＇s segmentation for solving numerical integration.A parameter has been introduced into expression of integral sum.Finally,several experimental results show that the proposed numerical integration method is more efficient and feasible compared with other numerical integration methods.
