This dissertation is driven by a question central to many industrial optimization problems : how to optimize a function when the budget for its evaluation is severely limited by either time or cost ? For example, when optimization relies on computer simulations, each taking several hours, the dimension and complexity of the optimization problem may seem irreconcilable with the evaluation budget (typically thirty parameters to be optimized with less than one hundred evaluations). This work is devoted to optimization algorithms dedicated to this context, which is out of range for most classical methods. The common principle of the methods discussed is to use Gaussian processes and Kriging to build a cheap proxy for the function to be optimize...
