#' This hyperband implementation evaluates hyperparameter configurations of equal budget across brackets in one batch.
#' For example, all configurations in stage 1 of bracket 3 and stage 0 of bracket 2 in one batch.
#' To select a parallel backend, use the `plan()` function of the \CRANpkg{future} package.
