Policy Window

A policy window display the policies for a given decision node. If the node is instantiated then the policy is ignored and the policy window is disabled . Only policies with parent configurations of a non-zero probability are displayed. This is indicated by collapsing columns corresponding to parent configurations of zero probability, which happens e.g. when a parent node has evidence entered (see Figures 1 and 2).
