%description
Successive Halving (Jamieson and Talwalkar (2016) <arXiv:1502.07943>) and
Hyperband (Li et al. 2018 <arXiv:1603.06560>) optimization algorithm for
the mlr3 ecosystem. The implementation in mlr3hyperband features improved
scheduling and parallelizes the evaluation of configurations. The package
includes tuners for hyperparameter optimization in mlr3tuning and
optimizers for black-box optimization in bbotk.
