To use HUGIN networks for computations, the HUGIN Graphical User Interface must be working in Run Mode. Figure 1 shows a Network Window in Run Mode. In Run Mode, the network window is split into a Node List Pane (unless this has been disabled via the Toggle Belief Bar item of the View Menu) on the left and a Network Pane on the right, showing the network. In the Node List Pane one can see the states of the nodes and their beliefs (also, expected utilities in LIMIDs), probabilities and expected utilities for decision nodes and mean & variance for continuous chance nodes). The states of a node appears when expanding it.
