mlr_test_functions

A simple mlr3misc::Dictionary storing well-known optimization test functions
as ObjectiveRFun objects.
Each objective has two additional fields beyond the standard ObjectiveRFun interface:<ul>
<li><code>optimum</code> (<code>numeric(1)</code>) - Known global optimum value (f*).</li>
<li><code>optimum_x</code> (<code><a href="/link/list()?package=bbotk&version=1.10.0" data-mini-rdoc="bbotk::list()">list()</a></code>) - List of known global optima (each a named list).</li>
</ul>For a more convenient way to retrieve test functions, see <code>otfun()</code>/<code>otfuns()</code>.

datasets

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'.

Methods

<ul>
<li><code>as.data.table(dict, ..., objects = FALSE)</code> 
mlr3misc::Dictionary -&gt; <code><a href="/link/data.table%3A%3Adata.table()?package=bbotk&version=1.10.0" data-mini-rdoc="bbotk::data.table::data.table()">data.table::data.table()</a></code> 
Returns a <code><a href="/link/data.table%3A%3Adata.table()?package=bbotk&version=1.10.0" data-mini-rdoc="bbotk::data.table::data.table()">data.table::data.table()</a></code> with fields "key", "label", "dimension",
"optimum", and "optimum_x" as columns.
If <code>objects</code> is set to <code>TRUE</code>, the constructed objects are returned in the list column named <code>object</code>.</li>
</ul>
