Understanding the Metrics

  • Avg Utility: Higher is better - overall match quality across all participants
  • Min Utility: Higher is better - ensures no one gets a terrible match
  • Max Utility: The best individual match score achieved
  • Fairness Score: Lower is better - measures equality of happiness distribution
