[rules-users] Iterative diagnosis - how to determine what is the next best fact?

Hi, I am new to Drools. I read the documentation and I looked at the examples, but I still not sure how to solve this problem: 1) Kind: iterative diagnosis Rules: if (A, B and C) then print ("Solution 1") if (A, B and not C) then print ("Solution 2") if (A, D and E) then print ("Solution 3") and so on... The entry should be something like this: * no facts are know * user answers a question (lets say A = true), I update the Statefull session and fire the rules * system chooses a unknow fact based on condition for the best incomplete rule. In this case, it would be B (as it knows A, but it doesn't know B or C) * user answers a new question (B = false), I update the session + fireRules * system now knows that rule 1 (A, B and C) is not possible. It also knows that rule 2 (A, B and not C) is not possible. So, it chooses the second condition on rule 3 (A, D and E), which is: what is D? * user answers a new question (D = true) .... * user answers a new question (E= true) * system prints: Solution 3! My big question: can I extract from the working memory or rule manager or the agenda a list of the rules that are 'almost' good to fire, but that still requires some of its conditions to be know (by inserting facts)?
