approximateRefPoints

E.g., for calculation of dominated hypervolume.

Framework for building evolutionary algorithms for both single- and multi-objective continuous or discrete optimization problems. A set of predefined evolutionary building blocks and operators is included. Moreover, the user can easily set up custom objective functions, operators, building blocks and representations sticking to few conventions. The package allows both a black-box approach for standard tasks (plug-and-play style) and a much more flexible white-box approach where the evolutionary cycle is written by hand.

approximateRefPoints function

<dl><dt>df</dt>
<dd>[<code>data.frame</code>] 
Data frame with the required structure, i.e. the data frame must contain a problem column "prob" as well as objective column(s).</dd>
<dt>obj.cols</dt>
<dd>[<code>character(&gt;= 2)</code>] 
Column names of the objective functions.
Default is <code>c("f1", "f2")</code>, i.e., the bi-objective case is assumed.</dd>
<dt>offset</dt>
<dd>[<code>numeric(1)</code>] 
Offset added to reference points.
Default is <code>0</code>.</dd>
<dt>as.df</dt>
<dd>[<code>logical(1)</code>] 
Should a data.frame be returned?
Default is <code>FALSE</code>. In this case a named list is returned.</dd></dl>
