Abstract: In an embodiment, a computer system performs a method of modifying a decision algorithm, such as an algorithm for assigning credit limits or other credit terms, via a graphical user interface. The system displays a graphical representation of a decision tree comprising a plurality of decision nodes. The decision nodes are associated with respective conditions, and at least a portion of the decision nodes are associated with an outcome to be assigned to an individual matching the associated respective conditions in accordance with the decision tree. The system receives a selection of a decision node and selects a parameter to be used to construct subnodes of the selected decision node, and constructs the subnodes. The system calculates an outcome for each subnode, and it updates the graphical representation of the decision tree to include the plurality of subnodes.
