%description
A modern and flexible approach to Bayesian Optimization / Model Based
Optimization building on the 'bbotk' package. 'mlr3mbo' is a toolbox
providing both ready-to-use optimization algorithms as well as their
fundamental building blocks allowing for straightforward implementation of
custom algorithms. Single- and multi-objective optimization is supported
as well as mixed continuous, categorical and conditional search spaces.
Moreover, using 'mlr3mbo' for hyperparameter optimization of machine
learning models within the 'mlr3' ecosystem is straightforward via
'mlr3tuning'. Examples of ready-to-use optimization algorithms include
Efficient Global Optimization by Jones et al. (1998)
