The only example that uses a SubChainChangeMoveSelector and a SubChainSwapMoveSelector is the vehicleRoutingProblem. The travelling-salesman-problem (which is another example for a problem with a chained PlanningVariable) does not use them. Is there a reason for this, e.g. what are the subChain*MoveSelectors for? The documentation of drools-planner 5.5.0.Final does not say anything about them, see chapter 7.3.4. subChainChangeMoveSelector and 7.3.5. subChainSwapMoveSelector Regards, Roman -- View this message in context: http://drools.46999.n3.nabble.com/planner-documentation-about-subChain-Mo...
