Traverse Instance

The "Traverse Instance" function can be invoked by selecting an instance node in run mode, and selecting either "Traverse Instance" from the Network Menu, or from the popup-menu (brought up by a right-click with the mouse).

The primary purpose of the traversal frame is the ability to explore the structure of instance nodes. The functionality of the traversal frame is very limited. Only operations concerning insertion and propagation of evidence are included. Any operations performed in the traversal frame is also performed on the main network (from which the traversal frame was invoked). By right-clicking on a node in the traversal frame, monitor windows for that node can be opened in the main network and in the traversal frame (See figure 1).
