Classical evolutionary approaches for multiobjective optimization are quite effective but incur a lot of queries to the objectives; this can be prohibitive when objectives are expensive oracles.

Physics-based models that capture the wake flow-field with high-fidelity are computationally very expensive to perform layout optimization of wind farms, and, thus, data-driven reduced order models can represent an efficient alternative for simulating wind farms.

Furthermore, we show that multiple optimization problems can be solved with the same machine learning model with high accuracy, to amortize the offline costs associated with constructing our models.

We propose a novel Bayesian method to solve the maximization of a time-dependent expensive-to-evaluate oracle.

For example, two sources of pressure fields about an aircraft are fused based on measured forces and moments from a wind-tunnel experiment.
