## Run Mode

When you test or use your HUGIN network for calculations, you are running in run mode. In figure 1 you can see a network window of a HUGIN network running in run mode. In run mode, the network window is split up in a node list pane on the left and a network pane where the graph describing the network is shown. In the node list pane you can view the states of the nodes and their beliefs (expected utility for decision nodes and mean/variance for continuous chance nodes). You view the states of a node by expanding it.

You go from edit mode to run mode by clicking the compile button in the tool bar of the edit mode network window or by selecting the Compile item of the network menu. Figure 2 shows the compile button.
