随机森林
说明： 用N来表示训练用例（样本）的个数，M表示特征数目。
输入特征数目m，用于确定决策树上一个节点的决策结果；其中m应远小于M。
从N个训练用例（样本）中以有放回抽样的方式，取样N次，形成一个训练集（即bootstrap取样），并用未抽到的用例（样本）作预测，评估其误差。
对于每一个节点，随机选择m个特征，决策树上每个节点的决定都是基于这些特征确定的。根据这m个特征，计算其最佳的分裂方式。
每棵树都会完整成长而不会剪枝，这有可能在建完一棵正常树状分类器后会被采用）。(N is used to represent the number of training cases (samples), and M is used to represent the number of features.
The number of input features m is used to determine the decision result of a node in the decision tree, where m should be far less than m.
From N training cases (samples), n times are sampled in the way of put back sampling to form a training set (i.e. bootstrap sampling), and the unselected cases (samples) are used to predict and evaluate the error.
For each node, m features are randomly selected, and the decision of each node in the decision tree is determined based on these features. According to these m characteristics, the best splitting mode is calculated.
Each tree will grow completely without pruning, which may be adopted after building a normal tree classifier).)

一堆猴子都有编号，编号是1，2，3 ...m ,这群猴子（m个）按照1--m的顺序围坐一圈，从第1开始数，每数到第N个，该猴子就要离开此圈，这样依次下来，直到圈中只剩下最后一只猴子，则该猴子为大王。-monkeys have a pile of numbers, numbers 1, 2, 3 ... m, these monkeys (m) In accordance with the 1-- m sitting in the order in a circle, starting from a few every few months to the first N, The monkeys will be leaving this ring, and so on down until the circle only last a monkey, the monkey king to.

Maze
说明： 用Qt C++框架开发的迷宫游戏，迷宫随机生成，可设置迷宫规模大小，可自动计算通关路径，按“w,a,s,d”键移动角色探索迷宫(到达终点后没有通关动作，有需要可自行写相关代码)，可更换游戏角色动作图、场景图等。(The maze game developed with QT C + + framework is randomly generated, and the maze scale can be set. Press "w,a,s,d" key to move the character to explore the maze (there is no clearance action after reaching the end point, you can write relevant codes if necessary), and the action diagram and scene diagram of the game character can be replaced.)
