default_acqfunction

Chooses a default acquisition function, i.e. the criterion used to propose future points.
For synchronous single-objective optimization, defaults to mlr_acqfunctions_ei.
For synchronous multi-objective optimization, defaults to mlr_acqfunctions_smsego.
For asynchronous single-objective optimization, defaults to mlr_acqfunctions_stochastic_cb.

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.
