[jboss-jira] [JBoss JIRA] (JBRULES-3440) No score reported in best solution if no steps taken

No score reported in best solution if no steps taken ---------------------------------------------------- Key: JBRULES-3440 URL: https://issues.jboss.org/browse/JBRULES-3440 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-planner Affects Versions: 5.4.0.Beta2 Environment: drools-planner-example 5.4.0-SNAPSHOT pulled via Maven on March 29. This is commit https://github.com/droolsjbpm/drools-planner/commit/ba38344b7563830eb2a72... Reporter: Chris Dolan Assignee: Geoffrey De Smet Priority: Minor Fix For: 5.4.0.Final Attachments: NonNullScoreTest.java If my initial solution guess is perfect and the solver exits before taking any steps, then solver.getBestSolution().getScore() is null. If I change my initializer so the first guess is intentionally wrong, then getScore() returns non-null. I would prefer that getScore() would be guaranteed to always return non-null after a successful solver.solve() invocation. Clearly the score is being computed because the log messages show it (see below). But the returned solution instance does not reflect that. By debugging, I can see that the returned solution is in fact the same instance that I passed in via setPlanningProblem() and not a clone. {noformat} 2012-03-30 15:42:53,283 INFO [DefaultSolver.java:172] Solving started: time spend (145), score (0hard/0soft), new best score (0hard/0soft), random seed (0). - o.d.p.c.s.DefaultSolver 2012-03-30 15:42:53,289 INFO [DefaultSolver.java:197] Solving ended: time spend (156), best score (0hard/0soft), average calculate count per second (6). - o.d.p.c.s.DefaultSolver {noformat}
