8人抢答器
说明： 基于AT89C51单片机设计制作一个抢答器，具体要求如下：
1、 设计一个智力竞赛抢答器，可同时共8名选手参加比赛，编号为1、2、3、4、5、6、7、8，各用一个按键。
2、 用一个按键作为主持人总开关，用来控制系统的清零和抢答的开始。
3、 抢答器开始后，数码管开始10秒倒计时，若有选手按动抢答按钮，在LED数码管上显示选手的编号，同时灯亮且伴随声音提示；倒计时完成后，选手不能在抢答；有人抢答成功后，要禁止其他选手抢答；最先抢答选手的编号一直保留到主持人将系统清零。(Based on AT89C51 single chip computer, a rush answerer is designed and manufactured. The specific requirements are as follows:
1. Designing an intelligence contest answering machine, which can be attended by 8 competitors at the same time, numbered 1, 2, 3, 4, 5, 6, 7 and 8, each with a button.
2. A key is used as the master switch of the host, which is used to clear the zero of the control system and start the rush response.
3. After the answering machine starts, the digital tube counts down 10 seconds. If a player presses the answering button and displays the player's number on the LED digital tube, the light is on and accompanied by sound prompts. After the countdown is completed, the competitor can't rush to answer. When someone rushes to answer successfully, other competitors are forbidden to rush to answer. The number of the first competitor is kept until the host clears the system.)

ACPLT/KS是用来为进程控制和进程控制工程而发展的一种开放式并且自由的通讯系统，是一种持续发展的成果.ACPLT/KS在异构的操作系统环境中提供非常简单的访问，不仅可以访问数据和参数，也包括归档连续时间和信息日志。另外（也非常重要）它也允许客户应用程序动态地获取数据信息，也就是，关于信息的信息，象数据进程，参量和档案之间的关系. 本程序是连接SCADA和DCS用的，使用GCC编译-ACPLT/KS is used for process control and process control engineering and the development of an open and free communications system, is an outcome of sustainable development .ACPLT/KS in heterogeneous operating system environment provides a very simple visit can not only access the data and parameters, including continuous-time and archived information log. In addition (very important) It also allows customers access to dynamic application data, that is, with regard to information information, such as data process, parameters and the relationship between files. This procedure is used to connect SCADA and DCS, and the use of GCC compiler

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).)
