Global optimization using random embeddings
Coralia Cartis, Estelle Massart, Adilet Otemissov
We propose a random-subspace algorithmic framework for global optimization of Lipschitz-continuous objectives, and analyse its convergence using novel tools from conic integral geo…

Constrained global optimization of functions with low effective dimensionality using multiple random embeddings
Coralia Cartis, Estelle Massart, Adilet Otemissov
We consider the bound-constrained global optimization of functions with low effective dimensionality, that are constant along an (unknown) linear subspace and only vary over the ef…
