             Summary: Planner: benchmark ranking algorithms must be failure safe (score is null)
                 Key: JBRULES-3491
                 URL: https://issues.jboss.org/browse/JBRULES-3491
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-planner
            Reporter: Geoffrey De Smet


Things that are problematic in the ranking code (all classes under org.drools.planner.benchmark.core.ranking):
- score can be null, totalScore can be null, ... when there are failures
- org.drools.planner.benchmark.core.ranking.TotalRankSolverBenchmarkRankingWeightFactory: Usage of SolverBenchmark.getScoreList() because some SolverBenchmark might have extra problem inputFiles.

The question is, should the ranking first compare the failureCount? Yes, I think it should.
What code should do that? the DefaultPlannerBenchmark, by default, or the rankers itself?
