Let's say I have some solution(NOT FINAL BEST SOLUTION) which done by human manually and I want get list of broken contraints for that solution, I've tried this.scoreDirector.setWorkingSolution(someSolution); this.scoreDirector.calculateScore(); Something like that should work. For the exact correct usage, see the new section for the 5.4.0.Final manual: https://hudson.jboss.org/hudson/view/Drools%20jBPM/job/drools-planner/las... It should never return null. I do in the examples all the time. There is a point though, that the code above still requires the creation of a Solver (but it doesn't you to actually run it): ScoreDirectorFactory scoreDirectorFactory = solverFactory.buildSolver().getScoreDirectorFactory();ScoreDirector guiScoreDirector = scoreDirectorFactory.buildScoreDirector();guiScoreDirector.setWorkingSolution(solution);Score score = guiScoreDirector.calculateScore(); Feel free to make a jira if you agree that it shouldn't be needed to do a ".buildSolver()" in that code. it returns *null* since it isn't connected with Solver then I've tried using Solver with <termination><maximumStepCount>0</maximumStepCount></termination>: this.scoreDirector.setWorkingSolution(someSolution); this.solver.setPlanningProblem(this.scoreDirector.getWorkingSolution()); this.solver.solve(); this.scoreDirector.setWorkingSolution(this.solver.getBestSolution()); this.scoreDirector.calculateScore(); then it shows *java.lang.UnsupportedOperationException* because there is no best solution in Solver java.lang.UnsupportedOperationException: StepCountTermination can only be used for phase termination. at org.drools.planner.core.termination.StepCountTermination.isSolverTerminated(StepCountTermination.java:40) at org.drools.planner.core.termination.OrCompositeTermination.isSolverTerminated(OrCompositeTermination.java:42) at org.drools.planner.core.solver.DefaultSolver.runSolverPhases(DefaultSolver.java:181) at org.drools.planner.core.solver.DefaultSolver.solve(DefaultSolver.java:151) how can implement this task? or I have to implement setBestSolution in Solver, i think this is bad idea... bad idea indeed -- View this message in context: http://drools.46999.n3.nabble.com/getting-list-of-broken-constraints-for-...
