Re: [rules-users] Drools Planner changing problem fact

last month, Ralph wrote: /All the examples in the drools-planner-examples seem to have a fixed list of problem facts (rooms, teachers, timeslots) which only should be combined optimally./ Just to address this one unanswered point. The Cloud Balancing example does support changing the problem facts, specifically by removing computers (bins). The last section of the planner documentation (section 12.4) addresses realtime planning, through the Solver.addProblemFactChange() API. This works whether you are removing problem facts (as the example shows) or modifying their contents. This generally restarts the Solver -- but, if you are relatively optimized, the adjustment is found relatively fast. (I'm curious, though -- does the Solver expressly prioritize doing moves associated with those problem facts that were just changed?) -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Planner-changing-problem-fact-tp...
