希尔伯特变换理论及其在工程领域的应用，介绍了原理及其实现方法(hibert transform)

说明：  这个是用基本粒子群优化算法解两个测试函数的最小值问题。(This is a fundamental particle swarm optimization algorithm using two test function solution of the minimum problem.)

这是一个关于商人visit许多城市，怎样走法才能使距离最短的例子，采样的了退火算法的经典案例(Traveling Salesman Problem (TSP) has been an interesting problem for a l me in classical optimization techniques which are based on linear and nonlin ogramming. TSP can be described as follows: Given a numberof cities to v d their distances from all other cities know, an optimal travel route has to und so that each city is visited one and only once with the least possible dista aveled. This is a simple problem with handful of cities but becomes complica the number increases.)
