Also in contrast to the traditional decision-tree approach, more than one of the rules in a decision tree may contribute to the solution of a problem for which the user is unable to provide a complete description. As shown by our results, increased coverage of incomplete problem descriptions is an important benefit for some decision trees. However, a potential risk in allowing a problem-solving dialogue to continue when relevant test results are not available is that no solution may be possible no matter what additional information the user can provide. This problem is addressed in our approach by using meta-level reasoning to recognize when no solution is possible.
