## Class TotalRankSolverRankingWeightFactory

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

- All Implemented Interfaces:
    SolverRankingWeightFactory

      public class TotalRankSolverRankingWeightFactory
      extends Object
      implements SolverRankingWeightFactory

  This `SolverRankingWeightFactory` orders a `SolverBenchmarkResult` by how many times each of its `SingleBenchmarkResult`s beat `SingleBenchmarkResult`s of the other `SolverBenchmarkResult`. It maximizes the overall ranking.

  When the inputSolutions differ greatly in size or difficulty, this often produces a difference in `Score` magnitude between each `PlanningSolution`. For example: score 10 for dataset A versus 1000 for dataset B. In such cases, this ranking is more fair than `TotalScoreSolverRankingComparator`, because in this ranking, dataset B wouldn't marginalize dataset A.
