介绍压缩传感理论中要用到的信号的稀疏表征原理(Introduced the theory of compressed sensing to use the sparse representation of signal theory)

在工程应用中 经常会遇到一些复杂的非线性系统, 这些系统状态方程复杂, 难以 用数学方 法准确建模。 在这种情况下, 可以 建立 BP 神 经网 络表达这些 非 线 性系 统。 该方法把未 知 系 统看成是一个黑箱, 首先用 系 统 输入输出 数据 训 练 BP 神 经网 络, 使网 络能 够表达该未 知 函 数, 然后就可以 用训练好的 BP 神经网络预测系统输出 。 本章拟合的非线性函 数为 y = x1^2+x2^2. 。 (In engineering applications often encounter some complex nonlinear systems, which complicated the equation of state, can not be accurately modeled mathematically. In this case, BP neural network can be established to express these nonlinear systems. The method of the unknown system as a black box, the first input and output data with systematic training BP neural network, the network can express the unknown function, then you can use the trained BP neural network forecasting system output. Chapter for fitting non-linear function y = x1 ^ 2+x2 ^ 2..)

现今社会网络越来越普及，网购已成为一种常见的消费方式，随之物流行业也渐渐兴盛，每个送货员需要以最快的速度及时将货物送达，而且他们往往一人送多个地方，请设计方案使其耗时最少。 这是数学建模是非常有意思的一个题，本程序用哈密尔顿算法计算(Today more and more popular social networks, online shopping has become a common way of consumption, with the attendant logistics industry has gradually flourished, each delivery person needs to be the fastest speed in time of goods delivery, and they sent the more often a a place, please design it for at least time-consuming. This is the mathematical modeling is a very interesting question, the program algorithm with the Hamilton)
