updateParetoArchive

This function updates a Pareto archive, i.e., an archive of non-dominated
points. It expects the archive, a set of individuals, a matrix of fitness values
(each column corresponds to the fitness vector of one individual) and updates
the archive &#8220;in-place&#8221;. If the archive has unlimited capacity all non-dominated points of
the union of archive and passed individuals are stored. Otherwise, i.e., in case
the archive is limited in capacity (argument <code>max.size</code> of
<code>initParetoArchive</code> was set to an integer value greater zero), the
<code>trunc.fun</code> function passed to <code>initParetoArchive</code> is applied to
all non-dominated points to determine which points should be dropped.

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.
