CallbackAsyncTuning: Asynchronous Tuning Callback

CallbackAsyncTuning R Documentation
Asynchronous Tuning Callback
Description
Specialized bbotk::CallbackAsync for asynchronous tuning.
Callbacks allow to customize the behavior of processes in mlr3tuning.
The callback_async_tuning() function creates a CallbackAsyncTuning.
Predefined callbacks are stored in the dictionary mlr_callbacks and can be retrieved with clbk().
For more information on tuning callbacks see callback_async_tuning().
