Re: [rules-users] [planner] The presumed score is corrupted

** Probably you forgot to notify the workingMemory.update in the doMove method: public void doMove(WorkingMemory workingMemory) { FactHandle factHandle = workingMemory.getFactHandle(activity); activity.setAssignee(...); workingMemory.update(factHandle, activity); } Op 14-10-11 09:21, Geoffrey De Smet schreef: A corrupted score normally indicates a problem with the Move implementation (or sometimes the score drl). Basically this happened: for a number of moves, it did the move, calculated the score and undo the move. One of those move was associated with a score -10hard/0soft, that was the best one. Now, it does that move (which is now called the "step") and when it calculates the score it's a different score 0hard/0soft. Try TRACE environment and see if it crashes sooner. Copy paste your Move implementation here.

In Planner 5.4 there will be 2 out-of-the-box Move implementations to use, so writing Move's become optional. Cool!

My rule file is very simple too and just counts the number of activities not assigned. When I run Solver.solve(), I get the following error message: Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: The presumedScore (-10hard/0soft) is corrupted because it is not the realScore (0hard/0soft). Presumed workingMemory: Score rule (remainingActivitiesCount) has count (1) and weight total (11). Real workingMemory: Score rule (remainingActivitiesCount) has count (1) and weight total (0). I've tracked down this message and found this piece of code @DefaultLocalSearchSolver.solveImplementation(): // there is no need to recalculate the score, but we still need to set it localSearchSolverScope.getWorkingSolution().setScore(localSearchStepScope.getScore()); if (assertStepScoreIsUncorrupted) { localSearchSolverScope.assertWorkingScore(localSearchStepScope.getScore()); } It seems that the working score is never updated along the algorithm, but the score in the working memory changes. Thus, when we use the DEBUG environment, assertStepScoreIsUncorrupted is turned on and the assertion fails. Should the score be updated or am I using the library incorrectly?
