Insights from ALLEGRO : Multi-Objective Optimization without ๐œ€-Constraints

In our recent analysis of Figure 35 from ALLEGRO , we explored the optimization landscape without ๐œ€-constraints and the outcomes were remarkable.

๐Ÿ“ˆ Key finding: Even in the absence of constraint tuning (indicated by “inf”), we identified a feasible solution that achieves energy and cost levels within 20% of their unconstrained optima. This highlights a surprising compatibility between energy efficiency and cost-effectiveness, an encouraging trait for practical applications that value both.

๐Ÿ•’ Delay dynamics: We observed that as the ๐œ€-constraint is relaxed, delay drops significantly. At ๐œ€ = 100% (where energy and cost can double from their optima), delay approaches its optimal value a favorable trade-off in latency-sensitive scenarios.

๐Ÿ’ธ Cost vs. others: Interestingly, when optimizing only for cost, the system shows less responsiveness to ๐œ€ changes. Even with substantial relaxations (up to 200% deviation for energy and delay), cost remains suboptimal. This points to a strong competitive tension between cost and the other objectives.

These findings are shaping how we think about multi-objective optimization in complex, real-world systemsโ€”where achieving balance is often more powerful than absolute optimization.
