均值变点是统计学中常用的变点分析方法，其主要思想如下： 假设有一组数据，随着某个指标变化（增大），其值逐渐增加并趋于稳定，如何判断在这个过程中是否出现了突变的情况，异样的情况？ 均值变点分析方法提供了一种思路，大概如下： 1 计算总的均值和方差； 2 循环将这组有序数据分成两组，X1，X2 计算各组的均值和方差， 计算总方差与分组方差之和的差； 3 得到变点(The change point of mean is a commonly used change point analysis method in statistics. Its main ideas are as follows: If there is a set of data, as a certain index changes (enlargement), its value increases gradually and tends to be stable. How to judge whether there is a sudden change in the process and the unusual situation? The mean change point analysis method provides a way of thinking, which is as follows: 1 the total mean and variance are calculated. The 2 cycle divides the ordered data into two groups, X1, X2. Calculate the mean and variance of each group. The difference between the sum of the total variance and the group variance is calculated. 3 get a change point)

说明：  求解双层规划问题常用的算法有极点算法、直接搜索法、下降法和非数值优化方法(如模拟退火算法、遗传算法等)，遗传算法的求解思路是：首先对上层的决策变量编码，代人下层规划模型，通过求解下层模型的决策变量值，代入上层模型计算适应度值，然后进行交叉、变异、选择操作，最后求出最优解。(Solving Bilevel Programming Problems with pole algorithm commonly used algorithms, direct search method, descent and non-numerical optimization methods (such as simulated annealing, genetic algorithms, etc.), genetic algorithm for solving approaches: the first on the top of the decision variable coding, on behalf of the were lower programming model, by solving the lower model of decision variables values into the upper model on behalf of the fitness value, and then crossover and mutation, select Options, and finally get the best solution.)
