mlr_optimizers_async_random_search

OptimizerAsyncRandomSearch

<p><code>OptimizerAsyncRandomSearch</code> class that implements a simple Random Search.</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'.
