dict_recombinators_xounif

RecombinatorCrossoverUniform

Values between two individuals are exchanged with component-wise independent probability.
This is a pseudo-class: It does not create a single R6-object of a class;
instead, it creates the object <code>rec("cmpmaybe", rec("swap"), p = 0.5)</code>,
making use of the <code>RecombinatorCmpMaybe</code> and <code>RecombinatorSwap</code> operators.

Evolutionary black box optimization algorithms building on the
'bbotk' package. 'miesmuschel' offers both ready-to-use optimization
algorithms, as well as their fundamental building blocks that can be used to
manually construct specialized optimization loops. The Mixed Integer Evolution
Strategies as described by Li et al. (2013) <doi:10.1162/EVCO_a_00059> can be
implemented, as well as the multi-objective optimization algorithms NSGA-II
by Deb, Pratap, Agarwal, and Meyarivan (2002) <doi:10.1109/4235.996017>.

dict_recombinators_xounif function

<dl><dt>keep_complement</dt>
<dd>(<code>logical(1)</code>) 
Whether the operation should keep both resulting individuals (<code>TRUE</code>), or only the first and discard
the complement (<code>FALSE</code>). Default <code>TRUE</code>.
The <code>$keep_complement</code> field will reflect this value.</dd></dl>

Arguments

Supported <code>Domain</code> classes are: <code>p_lgl</code> ('ParamLgl'), <code>p_int</code> ('ParamInt'), <code>p_dbl</code> ('ParamDbl'), <code>p_fct</code> ('ParamFct')

Supported Operand Types

This <code>Recombinator</code> can be created with the short access form <code>rec()</code>
(<code>recs()</code> to get a list), or through the the dictionary
<code>dict_recombinators</code> in the following way:
<div class="sourceCode"></div><pre><code># preferred:
rec("xounif")
recs("xounif") # takes vector IDs, returns list of Recombinators# long form:
dict_recombinators$get("xounif")
</code></pre>
