In continuous optimisation a given problem can be stated as follows: given the objective function f from R^n to R with n the dimension of the problem, find a suitable vector that minimises f up to an arbitrary numerical precision. In this context, the black-box scenario assumes that no information but the evaluation of f is available to guide its optimisation. In the first part, we study the Covariance Matrix Adaptation Evolution Strategy (CMA-ES) which is a well-established stochastic approach for solving Black-Box Optimisation (BBO) problems. We show its time and space complexity limits when addressing high-dimensional BBO problems. To overcome such limits, we provide variants of the CMA-ES that update only block-diagonal elements of the ...
