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 SingleBenchmarkResults beat SingleBenchmarkResults 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.
