[rules-users] Using planner to create an optimized changeset

Im interested in using Drools Planner to set the salience of a changeset, or possibly create a new changeset. So, using the Traveling salesmen problem, but this time the goal is to reduce the cost of the trip, we have a collection of rules, like (will write in english rather than MVEL) when traveling during holiday period when traveling to London avoid Heathrow when traveling more than 8 hours upgrade to business class ( so the salesperson is fresh) when flying into NYC stay at xyz hotel Would it be possible - or can anyone suggest ways of - generating a changeset (using Planner) of rules from another changeset, where the salience is set, and/or rules are added/removed? Thanks for you help. And very interested to hear your feedback.
