说明：  人工智能实验报告--蚁群算法 实验原理： 蚂蚁在觅食过程中可以找出巢穴到食物源的最短路径，为什么？ （1）信息素(pheromone) （2）正反馈现象：某一路径上走过的蚂蚁越多，则后来者选择该路径的概率就越大。 （3）挥发现象：路径上的信息素浓度会随着时间推进而逐渐衰减。
(Report of Artificial Intelligence--Ant Colony Algorithms Principle of experiment: Ants can find the shortest path from nest to food source in the process of foraging. Why? (1) pheromone (2) Positive feedback phenomenon: The more ants traveling on a certain path, the greater the probability that the latter will choose the path. (3) Volatilization: The pheromone concentration on the path will gradually decrease with time.)
