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 Solution
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 Solution
. 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
.
