Chang算法是一种利用探测和回声的方法,模仿Dijkstra-Scholten终止检测算法的思路。该算法初始时,每个节点的父节点都是自己。初始化者向每个邻居发送探测信息(probe),如果接收到回声(echo),则计数器(echo)加1,如果接收到探测信息,则将回声发送给发送者。节点j接收到探测信息后,将其发送给非父节点的邻居,并将发送者设置为其父节点。如果接收到回声,则计数器加1,如果接收到探测信息,则将回声发送给发送者。最后,节点将回声发送给父节点,并将其父节点设置为自己。

Chang's算法是一种分布式算法,用于在网络中查找树的根节点。该算法使用探测和回声,并且模仿了Dijkstra-Scholten终止检测算法的方法。该算法假定根节点已知,并最初将每个节点的父节点设置为自身。
启动程序发送探测消息到每个邻居节点。当一个节点接收到探测消息时,它首先将其父节点更新为消息的发送者。然后,它将探测消息转发到所有非父节点的邻居节点。如果一个节点接收到回声消息,则它将增加其回声计数器。如果一个节点接收到探测消息,则它将向探测消息的发送者发送回声消息。
该算法持续进行,直到节点接收到的回声消息数等于它发送的探测消息数。此时,节点知道已经找到了树的根节点。该节点然后向其父节点发送回声消息,并将其父节点更新为自身。
总的来说,Chang's算法是一种简单有效的方法,用于在分布式网络中查找树的根节点。
Probes do not plot to the Grapher for interactive simulation. Connect an oscilloscope or run a transient simulation to see Grapher data.
这个问题通常是由于Multisim中Grapher的设置不正确引起的。您可以按照以下步骤来解决这个问题:
1. 确认您的电路图中已经添加了Probe工具,并且已经将Probe的输出连接到了Grapher。
2. 点击Multisim工具栏中的“Grapher”按钮,打开Grapher窗口。
3. 在Grapher窗口中,点击“Settings”按钮,打开Grapher设置窗口。
4. 在Grapher设置窗口中,确保“Interactive Simulation”选项卡下的“Enable Interactive Simulation”选项已经被选中。
5. 如果您仍然无法在Grapher中看到Probe的输出数据,请尝试运行一个暂态分析,然后再次查看Grapher数据。
如果以上步骤都无法解决您的问题,请确认您的Multisim版本是否是最新的版本,并且您的电脑是否满足Multisim的最低系统要求。
