What should you check for in a decision tree to ensure that all paths can be reached?

In a decision tree, checking for logic conflicts is crucial to ensure that all paths can be reached. Logic conflicts occur when there are overlapping or contradictory conditions specified in the decision tree. If certain conditions are mutually exclusive or lead to contradictory outcomes, it may result in specific paths being unreachable. By identifying and resolving these conflicts, you can ensure that the decision tree functions as intended, allowing all possible paths to be evaluated based on the available input data.

The other aspects, such as row completeness, focus on whether all possible combinations of inputs have been accounted for in the decision tree, but they do not specifically address the reachability of paths in the same way that identifying logic conflicts does. Input value diversity examines the variety of data being considered, while evaluation efficiency relates to how optimally the decision tree processes those inputs—both of which are important, but not directly linked to ensuring all paths are reachable as logic conflicts are.
