Geoffrey De Smet commented on JBRULES-3592:
-------------------------------------------

This code suffers from the same problem:
  org.drools.planner.benchmark.core.DefaultPlannerBenchmark#determineSolverBenchmarkRanking
                
> Planner benchmark report: 2 SingleBenchmarks with the same Score should have the same ranking.

> For example, if on problem P1, the solvers have these scores:
> S1:  -800
> S2:   -50
> S3:   -50
> S4:    -2
> S5: -9000
> Then the ranking should be:
> S1: 3
> S2: 1
> S3: 1 // Currently this gets ranking 2 which is wrong
> S4: 0
> S5: 4
> The offending code is isolated in this 1 method:
>   org.drools.planner.benchmark.core.ProblemBenchmark#determineSingleBenchmarkRanking
