DBSCAN聚类算法

MD5文件签名算法的实现-MD5 Algorithm Implementation

这个应该是经典编程里面的经典算法实现的八皇后问题．也通过了测试．完全达到设计要求．-This should be a classic of the classic programming algorithm inside the eight Queen s problems. Also passed the test. Fully meet the design requirements.

一个表达式解析器， 可以解析二十多种运算符表达式， 支持优先级！-An expression parser, you can resolve more than 20 kinds of regular expression operators in support of priority!

我这是割线法和改进的欧拉法的源代码-This a secant method and improve the Eulerian method of source code!

该程序是用C语言写的采用了动量方法的BP神经网络，它具有极其强大的扩展性，可用于函数的逼近及分类识别等各方面，语言书写规范，其中大量使用了动态分配一、二维数组的方法，该网络实例中实现的是对某一函数的逼近，输入层为二层，中间层可自己设定多达十几层，逼近精度非常精确。读者可根据自己的需要设定各层的数目以及相应的训练样本进行训练与测试。-The program is written in C language using the momentum method of BP neural network, which has extremely powerful scalability, can be used for function approximation and classification in areas such as language specification, including large-scale use of a dynamically allocated one, two dimensional array of methods, examples of the network realize that the approximation of a function, for the second input layer, middle layer can be set as many as a dozen layers, close to very precise accuracy. Readers may need to be set in accordance with its own number of floors and the corresponding training samples for training and testing.

应用背景源代码是基于加密设置，试图加密数据到云服务器提高数据安全属性分叉版密文政策。关键技术其关键技术在于密文策略算法借用ASE加密算法

fast Ica matlab算法，经过试验验证了，希望对大家有用处-fast algorithm, the test after test, we hope to be useful

客户端之间发送PING报文，客户端接受其他客户端的PING报文，回复信息。个人想法：通过UDP连接，客户端与服务器建立连接，登录只要用户名（不能重复），能从服务器查询在线用户。

应用背景Massive multiuser MIMO (MISO): ◮ M ≫ K ≫ 1 (think 100 × 10 or 500 × 50) ◮ coherent, but simple, processing ◮ Potential to dramatically improve rate & reliability ◮ Potential to drastically scale down TX power ◮ Not only theory, at least one known testbed (64× ∼10) 关键技术 Massive MIMO Operation Not enough resources for pilots & CSI feedback, so operate in TDD. ◮ On the uplink, ◮ acquire CSI from uplink pilots and/or blindly from data ◮ detect symbols ◮ M ≫ K ⇒ linear processing (MRC, ZF, MMSE) nearly optimal ◮ On the downlink, ◮ use CSI obtained on the uplink ◮ make necessary adjustments based on reciprocity calibration ◮ apply multiuser MIMO precoding ◮ simple precoders desirable (and very good!): MRT, ZF, MMSE, ... ◮ MRC/MRT operation ◮ intracell interference will appear as
