由于遗传算法较以往传统的搜索算法具有使用方便、鲁棒性强、便于并行处理等特点，因而广泛应用于组合优化、结构设计、人工智能等领域。(Than in the past due to genetic algorithms traditional search algorithms with easy to use, robustness, ease of parallel processing, etc., which are widely used in combinatorial optimization, structural design, artificial intelligence and other fields.)

通过matlab模拟仿真光反馈半导体激光器的非线性动态输出特性，主要包括单周期振荡，倍周期振荡，四倍周期振荡和混沌振荡等。(Research program by matlab optical feedback semiconductor laser output characteristics of nonlinear dynamics, there are single-cycle oscillation, the oscillation cycle times, four times the oscillation cycle oscillations and chaos.)

标准粒子群优化算法的程序。运用matlab编写。(Standard particle swarm optimization procedures. Using matlab prepared.)

Huffman code的matlab程序，用一幅图像作为training image得到像素的Huffman编码，然后编码另外一幅图像，求得average code length。(Huffman code of matlab program, with an image as a training image pixel Huffman coding, then coded another image obtained average code length.)

粒子群优化算法的一个寻优案例,测试函数含有多个局部极值，尝试用PSO算法寻找全局极值(a case of Particle Swarm Optimization algorithm.)

对一维信号进行OMP重构，基于压缩感知的信号重构(OMP reconstruction, one-dimensional signal based on compressed sensing signal reconstruction)

层次分析（AHP）/网络分析（ANP)Analytic Hierarchy Process是一种十分实用的决策方法。 是对一些较为复杂、较为模糊的问题作出决策的简易方法，它特别适用于那些难于完全定量分析的问题 num:包括目标层和方案层的总层数 g:行向量（各层准则数量，包括目标层（第一层）和方案层（最后一层））。 w：返回值w是最后决策的方案层的权重，根据输出选择最佳方案 在输入矩阵时请加‘[]’号，否则会出现语法错误。 调运方式：w=hierarchy(num,g)( Analytical Hierarchy (AHP)/Network Analysis (ANP) Analytic Hierarchy Process is a very practical approach to decision making. Is the easy way of making some of the more complex, more ambiguous issues make it particularly difficult for those who complete quantitative analysis of the problem num: The total number of layers including the target layer and the solution layer g: row vector (layers Guidelines number, including the target layer (first layer) and program level (the last level)). W: w The return value is the right solution layer of the final decision of the heavy, choose the best option based on the output when the input matrix please add ' []' No, there would be a syntax error. Transporting way: w = hierarchy (num, g))
