作用函数 [zuò yòng hán shù]
action function
- 考虑种群多样性与进化代数的关系，提出一个作用函数。
Taking the relation between diversity of evolution population and evolution time into account an effect function was present. - 在此基础上，提出一种自适应遗传算法，该算法中交叉和变异操作的点数随种群多样性函数和作用函数而变化。
Based on it, a novel adaptive genetic algorithm was put forth, in which the points of crossover and mutation operators change with diversity of evolution population and effect factor. - 两个实例的应用结果表明:人工神经网络通过神经原作用函数的简单复合就能逼近有限子集的任意非线性函数，而传统的统计方法则存在着如何选择模型形式及非线性优化问题，表现出明显的局限性，并且统计模型的更新工作相当繁重。
Compared with CSM, two examples proved that ANN could be trained successfully, even if the available data were insufficient and irregular, while CSM showed the limit in selecting model type and non-linear optimization.
