- 对具有随机噪声的二阶系统的模型辨识，进行标幺化以后系统的参考模型差分方程为： y(k)=a1*y(k-1)+a2*y(k-2)+b*u(k-1)+s(k) 式中，a1=0.3366,a2=0.6634,b=0.68,s(k)为随机噪声。由于神经网络的输出最大为1，所以，被辨识的系统应先标幺化，这里标幺化系数为5。采用正向建模(并联辨识)结构，神经网络选用3-9-9-1型，即输入层i，隐层j包括2级，输出层k的节点个数分别为3、9、9、1
预测
- 数据预测算法，主要是一元n次方程的回归预测实现。* 预测分析--本算法只适用于有明显线性趋势的数据 * 默认为一元二次曲线方程法 * * 本程序主要涉及有两个算法 * 1．用最小二乘原理找到线性方程组的系数和常数。 * 2．解线性方程组 * 本程序在解线性方程组中，由于考虑到收敛性问题未采用迭代法，而是采用Gauss-Jordan消去法来解决。-data prediction algorithm is mainly one yuan n
逢山开路模型
- 在本问题的求解中，修桥和挖隧道是两个相类似的求解过程，我们将求解过程分为两个部分：第一、对河岸边一固定点 ，将桥修在 处时，求解由起始点 到经固定点 到居民点 的最短路线。第二、如何确定 的位置，使得总路线的费用最小。我们分别用了两个模型来进行这两部分内容的求解。模型一、针对坡度的限制，利用小区域内的局部最优来达到全局最优。模型二、列出点 有一定的位移时，可以减少的费用 的函数方程，然后利用河岸附近等高线较紧密，公路不能沿偏离等高线方向
