In optimization approaches to engineering applications, time-consuming simulations are often utilized which can be configured to deliver solutions for various fidelity (ac- curacy) levels. It is common practice to train hierarchical surrogate models on the objective functions in order to speed-up the optimization process. These operate under the assumption that there is a correlation between the different fidelities that can be exploited to cheaply gain information. However, limited guidelines are…

Some considerations regarding the use of multi-fidelity Kriging in the construction of surrogate models
TLDR
The following paper illustrates the potential pitfalls of choosing one technique over the other without a careful consideration of the optimization problem at hand by defining and validate a set of guidelines for the creation of a multi-fidelity Kriging model.
Multi-fidelity Gaussian process regression for computer experiments
TLDR
This thesis deals with a conjecture about the dependence of the learning curve (ie the decay rate of the mean square error) with respect to the smoothness of the underlying function, which allows for addressing rigorously practical questions such as the optimal allocation of the budget between different levels of codes in the multi-fidelity framework.

Multi-fidelity black-box optimization for time-optimal quadrotor maneuvers
TLDR
A multi-fidelity Bayesian optimization framework is proposed that models the feasibility constraints based on analytical approximation, numerical simulation, and real-world flight experiments and resulting trajectories were found to be significantly faster than those obtained through minimum-snap trajectory planning.
