MATLAB和AForge.NET实现的神经网络模型源代码，有例子 ， 适合初学者 (MATLAB and AForge.NET realize neural network model source code, there are examples for beginners)

结构随机振动中关于Newmark 与精细积分法的对比，在精度一致的情况下效率的提高( a small program about Newmark and NPDL)

用Wilson方法计算结构动力反应(无阻尼)(Wilson calculated using the structure of dynamic response (without damping))

基于matlab环境下的混沌粒子群优化算法源程序，用于求解多种优化（线性、非线性等）问题。(Optimization based on chaotic particle swarm algorithm source matlab environment, used to solve a variety of optimization (linear and nonlinear) problems.)

说明：  多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscalePermutationEntropy函数中的PermutationEntropy也可以单独拎出来计算单个样本熵。(The multi-scale sample entropy program, which is used for a section of bearing fault data in an example, is simple and easy to understand. The permutationentropy in the multiscale permutationentropy function can also be carried out separately to calculate the entropy of a single sample.)

说明：  对策论的学习，用于算法研究和编程~~~~(Measures of learning, research and programming for the algorithm ~ ~ ~ ~)

考虑到通信网络结点的可靠性，若要求任意一个结点出现故障时，其它结点间仍然能够保持通信畅通的可能性都达到90 ，请建立问题的数学模型，设计求解算法，并给出使总铺设费用最少的铺设方案(Considering the reliability of communication network nodes, if you want any one node fails, you can still keep communication flowing between the possibility of other nodes are reached 90 , please build a mathematical model of the problem, the design algorithm, and give up some laying scheme of total laying cost at least)
