Class TotalRankSolverBenchmarkRankingWeightFactory

java.lang.Object
  org.drools.planner.benchmark.core.ranking.TotalRankSolverBenchmarkRankingWeightFactory

All Implemented Interfaces:

SolverBenchmarkRankingWeightFactory

public class TotalRankSolverBenchmarkRankingWeightFactory
extends Object
implements SolverBenchmarkRankingWeightFactory

This SolverBenchmarkRankingWeightFactory orders a SolverBenchmark by how how many time each of it's SingleBenchmark beat the SingleBenchmark of the other SolverBenchmarks. It maximizes the overall ranking.

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