针对传统的算法如遗传算法、粒子群算法等在TSP问题上求解精确性和求解规模上都还有一定的不足，本文提出了一种基于动态规划思想的粒子群优化算法。该算法用动态规划的方法实现粒子间的信息交互和粒子的进化，并且将粒子群中的粒子按无标度信息指导网络拓扑图的方式进行连接。仿真结果表明该方法能有效地减小误差率，提高解的精确，同时还保持了较低的计算复杂度，具有良好的稳健性。(TSP problem solving for the traditional algorithms such as genetic algorithms, particle swarm optimization accuracy and solving the scale, there is a certain lack of a dynamic programming algorithm-based particle swarm optimization algorithm. The algorithm using dynamic programming method to achieve the evolution of information exchange between the particles and the particles, and particle swarm particle scale-free information guide network topology map to connect. The simulation results show that this method can effectively reduce the error rate and improve the solution precision, while maintaining a low computational complexity, good soundness.)

它是一个计算热通量的c++程序，用udf导入fluent，既可以求解，非常好用的一个，可以作为入门的一个例子学习。(it is a calculated heat flux of c++ program, with udf into fluent, not only can solve, very easy to use one, can be used as a case study entry.)

外国人写的卡尔曼滤波器算法的库，可以供大家参考，已经封装好了(kalman library)

fluent 改进的全空化模型，针对可压缩流，内有声速处理(fluent improved full cavitation model for compressible flow, there are the speed of sound processing)

本程序是用数学方程试计算出一个点在一条线上的垂线坐标，并判断出在线内外，是测量中用的程序！(The test procedure is used to calculate the mathematical equation of a line a point in the vertical coordinate, and determine the line outside, the procedure used to measure!)
