mlr_optimizers_async_design_points

OptimizerAsyncDesignPoints

<p><code>OptimizerAsyncDesignPoints</code> class that implements optimization w.r.t. fixed design points.
We simply search over a set of points fully specified by the ser.</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'.
