M1 |
Ranks strictly by Metric 1. |
Single-metric evaluation. |
M1_M2 |
Metric 1 is primary. Metric 2 can correct (swap) ranks if a lower-ranked method significantly outperforms a higher-ranked one in Metric 2. |
Balancing performance vs. cost. |
M1_M3A |
Metric 1 is primary. Metric 2 acts strictly as a tie-breaker. |
Tie-breaking without overriding primary results. |
M1_M2_M3 |
Full hierarchy. M1 is primary. M2 corrects M1 (iterative). M3 applies two sub-logics: (1) One-time correction if M2 is neutral, and (2) Iterative tie-breaking if both M1 and M2 are neutral. |
Complex multi-objective benchmarking. |
