GM(1_1)
GM(1,1)模型1-4
1:GM(1,1)模拟模型,在matlab中的输入方法为gm1(x),x指要模拟的序列。
2:GM(1,1)预测模型,在matlab中的输入方法为gm2(x,K),x指要模拟的序列,K指从以后序列第一个数据算起的第k个待预测数据。
3:GM(1,1)群模拟模型,在matlab中的输入方法为gm3(x),x指要模拟的序列。
4:GM(1,1)群预测模型,在matlab中的输入方法为gm4(x,K),x指要模拟的序列,K指从以后序列第一个数据算起的第k个待预测数据。
gm4对序列趋势比较好的数据预测效果较好,对上下变动的数据,特别是后4个数据趋势跟前面的数据相反的,预测效果很差。
gm2对上下变动的数据,预测效果比gm4好,但对趋势较好的数据,预测精度没有gm4高。
gm3比gm1模拟精度要高。
可以以x=[1 3 5 7 9 11 13 15]进行实验。x输入默认行向量。
所有程序在matlab6.0上调试通过。(GM (1,1) 1-4 1 : GM (1,1) simulation model Matlab in the input method for gm1 (x), x entail simulation sequence. 2 : GM (1,1) model, in the Matlab input method for gm2 (x, K), x entail simulated sequence, from the K refers to the first series after a run of data k pending forecast data. 3 : GM (1,1)- simulation model, in the Matlab input method for gm3 (x), x entail simulation sequence. 4 : GM (1,1)- forecasting model, in the Matlab input method for gm4 (x, K), x entail simulated sequence, from the K refers to the first series after a run of data k pending forecast data. Gm4 right sequence relatively good trend data predicted better results, the next change in the data, especially after four data with the previous trend data contrary, predict poor. Gm2 next to the change in forecast resu)

tsp_nn
旅行商问题(TSP)的最近邻(NN)算法
近邻算法产生不同的结果,取决于选择哪个城市作为起点。此功能决定近邻路线为多个出发点,并返回这些航线的最佳。
(TSP_NN Traveling Salesman Problem (TSP) Nearest Neighbor (NN) Algorithm
The Nearest Neighbor algorithm produces different results depending on which city is selected as the starting point. This function determines the Nearest Neighbor routes for multiple starting points and returns the best of those routes)
