#' @param resampling ([mlr3::Resampling])\cr
#' Resampling that is used to evaluate the performance of the hyperparameter configurations.
#' Uninstantiated resamplings are instantiated during construction so that all configurations are evaluated on the same data splits.
#' Already instantiated resamplings are kept unchanged.
#' Specialized [Tuner] change the resampling e.g. to evaluate a hyperparameter configuration on different data splits.
#' This field, however, always returns the resampling passed in construction.
