For the stochastic (or randomized) part we will present concepts ensuing from Evolution Strategies and Estimation of Distribution Algorithms, discussing step-size and covariance matrix adaptation techniques. We will in particular present the CMA-ES algorithm.\u003C\/p\u003E\n\u003Cp\u003EThe course will cover theoretical aspects of the methods related to invariance, (linear) convergence as well as practical ones. The students will have the opportunity to implement or to use the implementation of certain algorithms, to learn how to recognize and to diagnose numerical problems and the failure of one algorithm as well as to identify the convergence type. We will also explain how to conduct (fair) performance assessment.\nIn the last part we present concepts related to multiobjective optimization.\u003C\/p\u003E\u003C\/span\u003E\n                      \u003C\/div\u003E\n                  \u003C\/div\u003E\n        \u003Cdiv class=\u0022field-spacing\u0022\u003E\n      \u003Cdiv class=\u0022field__label h3 dash\u0022\u003EObjectifs d\u0026#039;apprentissage\u003C\/div\u003E\n                        \u003Cdiv class=\u0022mt-5 text-justify\u0022\u003E\n                                      \u003Cspan\u003E\u003Cp\u003EChallenging numerical optimization problems occur in many domains in industry, medicine, biology, physics, \u2026 The underlying functions can be non-convex, non-differentiable, non-smooth, ill-conditioned and noisy. Often, the gradient of the function is not available (or does not exist). In this context, derivative-free optimization techniques, also referred to as zero order black-box optimization techniques, are needed.\u003C\/p\u003E\n\u003Cp\u003EThe objective of this lecture is to present the main deterministic and stochastic derivative-free optimization algorithms used nowadays.\u003C\/p\u003E\u003C\/span\u003E\n                      \u003C\/div\u003E\n                  \u003C\/div\u003E\n                                \u003Cdiv class=\u0022field-spacing\u0022\u003E\n      \u003Cdiv class=\u0022field__label h3 dash\u0022\u003EBibliographie\u003C\/div\u003E\n                        \u003Cdiv class=\u0022mt-5 text-justify\u0022\u003E\n                                      \u003Cspan\u003E\u003Cp\u003EIntroduction to Derivative Free Optimization, A.
