题目链接:The 18th Zhejiang University Programming Contest Sponsored by TuSimple - G Traffic Light 题解: 题意自己翻译,此题首先肯定是要广搜的,不过要开一个1e5*1e5的数组好像有点困难, 所以用结构体来存每个点的下标,然后从源点开始广搜.定义一个pair<node,int>,第一个存节点信息,第二个存到当前节点的步数,因为还要处理到达每个节点的状态. 状态:走奇数步并且状态为1与走偶数步状态为0的结果…

概要 在sdn下,控制平面基于网络测量的的数据控制网络,而细粒度的管理得益于细粒度的测量数据.针对sdn环境下的细粒度测量(识别具体应用程序),可以实现对细粒度的流量管控. 设计了识别系统SBAR,对数据流进行测量,识别出具体应用程序并得到它们的网络数据.针对流分类,SBAR以应用程序协议为参照,使用了机器学习的算法. 针对web和加密流量,使用深度包检测检测包的负载以识别应用程序.同时SBAR利用了OpenFlow提供的测量数据识别应用,交换机利用南向接口向控制器传输数据.最后使用GUI对得到…

项目的要求很简单: 模拟出十字路口的交通控制情况: 秒. 当东西(或南北)方向红灯时,所有车辆(除了消防车.救护车.警车)均排队等待,当东西(或南北)方向绿灯时,所有车辆按序行驶(不准超车). 制作这个小框体程序我选择的平台是JAVA,实现结果效果图如下所示: 首先分析整个项目题目上的要求,在十字路口上通过的车辆可以抽象为两类:普通车辆和特殊车辆(包括警车,消防车,救护车等),所谓普通的车辆和特殊种类的车辆之间的差别是是否需要在红绿灯路口之前进行等待操作,特殊车辆享有优先权并且可以直接通过路口,…
