QUIVER: Cost-Aware Adaptive Preference Querying in Surrogate-Assisted Evolutionary Multi-Objective Optimization

Florian A. D. Burnat

QUIVER adaptively chooses between objective evaluations and two types of preference queries to maximize expected decision quality gain per unit cost, reaching 25% lower final utility regret than fixed strategies on hard benchmarks.

Claims

C1strongest claim

QUIVER achieves the lowest final utility regret on challenging WFG problems (utility regret of 2.14 on WFG4, 2.82 on WFG9: a 25% improvement over baselines), outperforming all single-modality baselines.

C2weakest assumption

The synthetic decision-maker models used to simulate preference responses and costs accurately represent real human behavior and query costs in the target application domains.

C3one line summary

QUIVER adaptively balances cheap pairwise preference queries and costly indifference adjustments with objective evaluations to achieve lower utility regret than single-modality baselines on WFG benchmarks.
