Individual nodes can be retrieved using <code>getNode()</code> + which requires the row and column to be specified. The same works for + inputs and outputs using the associated getters, in which case only the + index is necessary. + <br><br> + In evolutionary computation it is often necessary to make copies of + chromosomes; this can be accomplished in JCGP in two ways. The recommended + way to do this is using <code>copyChromosome()</code> in <code>Population</code>, but alternatively + it can be done by using the <code>Chromosome</code> copy constructor and specifying the + object to copy from, or by using the <code>copyGenes()</code> method. + <br><br> + To illustrate this, given two chromosomes, chr1 and chr2, the following code: + <br><br> + <code> + chr1.copyGenes(chr2); + </code><br><br> + will modify all of chr1's connections and functions to match those of chr2, without + creating a new instance. In contrast, + <br><br> + <code> + chr1 = new Chromosome(chr2); + </code><br><br> + creates a new instance of chromosome which is identical to chr2 and assigns it to chr1, + meaning any old references to chr1 that are not updated will still refer to a chromosome + that is not identical to chr2. In practice, the most reliable way is to use the copy method + in <code>Population</code>. Assuming chr1 and chr2 are indexed 1 and 2 in <code>population</code> respectively, + <br><br> + population.copyChromosome(2, 1); + <br><br> + will copy chr2 into chr1 without creating new instances or requiring access to the underlying + chromosome array. <code>Chromosome</code> offers a variety of methods to compare chromosomes as well, + such as <code>compareGenesTo()</code> and <code>compareActiveGenesTo()</code>. <code>Comparable</code> is implemented + to compare fitness value, meaning <code>compareTo()</code> returns a value depending the relative fitness + of the compared chromosomes. + <br><br> + In order to set the chromosome's input values for decoding, <code>setInputs()</code> should be used. A few + utility methods are provided in order to retrieve random elements from the chromosome, which are used + internally to initialise with random connections but also externally by mutators when performing + mutations.</div> +<dl> +<dt><span class="simpleTagLabel">Author:</span></dt> +<dd>Eduardo Pedroni</dd> +</dl> +</li> +</ul> +</div> +<div class="summary"> +<ul class="blockList"> +<li
