Multi-fidelity constraints in blackbox optimization
Stéphane Alarie, Charles Audet, Miguel Diago +2
This work studies constrained blackbox optimization problems that cannot be solved in reasonable time due to prohibitive computational costs. This challenge is especially prevalent…
Fidelity and interruption control for expensive constrained multi-fidelity blackbox optimization
Stéphane Alarie, Charles Audet, Miguel Diago +2
This work introduces a novel blackbox optimization algorithm for computationally expensive constrained multi-fidelity problems. When applying a direct search method to such problem…
Hierarchically constrained blackbox optimization
Stéphane Alarie, Charles Audet, Paulin Jacquot +1
In blackbox optimization, evaluation of the objective and constraint functions is time consuming. In some situations, constraint values may be evaluated independently or sequential…
Parallel Surrogate-assisted Optimization Using Mesh Adaptive Direct Search
Bastien Talgorn, Stéphane Alarie, Michael Kokkolaras
We consider computationally expensive blackbox optimization problems and present a method that employs surrogate models and concurrent computing at the search step of the mesh adap…
Optimization of noisy blackboxes with adaptive precision
Stéphane Alarie, Charles Audet, Pierre-Yves Bouchet +1
In derivative-free and blackbox optimization, the objective function is often evaluated through the execution of a computer program seen as a blackbox. It can be noisy, in the sens…
