This mlr3misc::Callback drops the remaining tasks of the initial design from the queue when a configurable fraction (initial_design_fraction) of the runtime limit is reached. The initial_design_fraction is set to 0.25 by default.

Examples

clbk("mlr3automl.initial_design_runtime", initial_design_fraction = 0.5)
