The paper presents a hierarchical Bayesian optimization framework that uses Gaussian process meta-modeling to address the challenges of optimizing complex system-of-systems (SoS) architectures. It handles discrete architectural choices, conditional dependencies, and heterogeneous design variables, improving search efficiency and robustness over conventional surrogate-based methods. The approach is demonstrated on an aircraft-based multi-agent system for wildfire suppression, showing its applicability to large, diverse design spaces with limited simulation budgets.

The paper evaluates the Tabular Prior-data Fitted Network (TabPFN) as a surrogate model in surrogate‑assisted evolutionary algorithms (SAEAs) for expensive optimization problems. Through extensive experiments in both offline and online settings across a range of problem types—including single‑objective, multi‑objective, constrained, combinatorial, mixed‑variable, and engineering tasks—the study finds that TabPFN’s effectiveness varies strongly with the problem characteristics. The authors conclude that TabPFN should be used selectively, with customized model management and algorithm design tailored to data availability, landscape complexity, and search‑space properties.
