ContextAsync

<p>A CallbackAsync accesses and modifies data during the optimization via the <code>ContextAsync</code>.
See the section on active bindings for a list of modifiable objects.
See <code>callback_async()</code> for a list of stages which access <code>ContextAsync</code>.</p>

Features highly configurable search spaces via the 'paradox'
package and optimizes every user-defined objective function. The
package includes several optimization algorithms e.g. Random Search,
Iterated Racing, Bayesian Optimization (in 'mlr3mbo') and Hyperband
(in 'mlr3hyperband'). bbotk is the base package of 'mlr3tuning',
'mlr3fselect' and 'miesmuschel'.
