xegaDfMutationFactory

<code>xegaDfMutationFactory()</code> implements the selection
 of one of the mutation functions in this
 package by specifying a text string.
 The selection fails ungracefully (produces
 a runtime error), if the label does not match.
 The functions are specified locally.
Current support:
<ol>
<li>"MutateGene" returns <code>xegaDfMutateGeneDE()</code>.
 To provide a working default for more than 
 one gene representation.</li>
<li>"MutateGeneDE" returns <code>xegaDfMutateGeneDE()</code>.</li>
</ol>

Representation-dependent gene-level operations
for genetic and evolutionary algorithms with real-coded genes
used in the R-package 'xega' <https://CRAN.R-project.org/package=xega>
are collected in this package. The common feature of the gene
operations is that all of them are useful for derivation-free
optimization algorithms. At the moment the package
implements initialization, mutation, crossover, and replication
operations for differential evolution as described in
Price, Kenneth V., Storn, Rainer M. and Lampinen, Jouni A. (2005)
<doi:10.1007/3-540-31306-0>. In addition, several (more recent)
methods for determining the scale factor are provided.
For 'xega''s architecture,
