## Class TotalScoreSolverRankingComparator

- java.lang.Object
- - org.optaplanner.benchmark.impl.ranking.TotalScoreSolverRankingComparator

- All Implemented Interfaces:
    Serializable, Comparator<SolverBenchmarkResult>

      public class TotalScoreSolverRankingComparator
      extends Object
      implements Comparator<SolverBenchmarkResult>, Serializable

  This ranking `Comparator` orders a `SolverBenchmarkResult` by its total `Score`. It maximize the overall score, so it minimizes the overall cost if all `PlanningSolution`s would be executed.

  When the inputSolutions differ greatly in size or difficulty, this often results in a big difference in `Score` magnitude between each `PlanningSolution`. For example: score 10 for dataset A versus 1000 for dataset B. In such cases, dataset B would marginalize dataset A. To avoid that, use `TotalRankSolverRankingWeightFactory`.
