代码说明:

c# 版的多线程 网络爬虫程序,抓取网页信息,供初学者学习.自定义线程数.可设置网页保存路径. 1.把爬虫队列从先入先出换成优先队列, 即可得到带偏好的爬虫 (Preferential Crawler).  2.带偏好的爬虫给尚未访问的页面链接赋予优先级, 该优先级根据对页面的估计计算而得. 3.拓扑属性, 如目标页面的入度.  4.内容属性, 如程序目标和页面至今的相似度.  

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    用通用图搜索算法实现农夫过河问题,建立了通用图搜索算法的模板,可以稍作改动解决其他如汉诺塔问题、水壶倒水问题等(The general graph search algorithm is used to realize the problem of farmer crossing the river, and the template of the general graph search algorithm is established, which can solve other problems such as the Hannover Tower problem and the water pouring problem of the kettle with slight modification.)

  • FuzzyPAdaptivePRobustPPIDPController
    适合用来学习模糊控制的源码。模糊自适应PID效果是非常不错。PID控制器,一种工业控制方式,比例积分微分控制规律(控制器数学模型G(S)=比例+微分+积分),经常用P表示比例,用I表示积分,用D表示微分。(Suitable for learning fuzzy control of the source. Fuzzy adaptive PID effect is very good. PID controller, an industrial control, PID control law (mathematical model of the controller G (S) = ratio of+ differential+ points), often expressed by P ratio, with the points I said, with the D that differential.)
