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 class="blockList"> -<!-- ======== CONSTRUCTOR SUMMARY ======== --> -<ul class="blockList"> -<li class="blockList"><a name="constructor.summary"> -<!-- --> -</a> -<h3>Constructor Summary</h3> -<table class="memberSummary" border="0" cellpadding="3" cellspacing="0" summary="Constructor Summary table, listing constructors, and an explanation"> -<caption><span>Constructors</span><span class="tabEnd"> </span></caption> -<tr> -<th class="colOne" scope="col">Constructor and Description</th> -</tr> -<tr class="altColor"> -<td class="colOne"><code><span class="memberNameLink"><a href="../../../jcgp/backend/population/Chromosome.html#Chromosome-jcgp.backend.population.Chromosome-">Chromosome</a></span>(<a href="../../../jcgp/backend/population/Chromosome.html" title="class in jcgp.backend.population">Chromosome</a> clone)</code> -<div class="block">Copy constructor.</div> -</td> -</tr> -<tr class="rowColor"> -<td class="colOne"><code><span class="memberNameLink"><a href="../../../jcgp/backend/population/Chromosome.html#Chromosome-jcgp.backend.resources.Resources-">Chromosome</a></span>(<a href="../../../jcgp/backend/resources/Resources.html" title="class in jcgp.backend.resources">Resources</a> resources)</code> -<div class="block">Initialise a chromosome with the specified parameters.</div> -</td> -</tr> -</table> -</li> -</ul> -<!-- ========== METHOD SUMMARY =========== --> -<ul class="blockList"> -<li class="blockList"><a name="method.summary"> -<!-- --> -</a> -<h3>Method Summary</h3> -<table class="memberSummary" border="0" cellpadding="3" cellspacing="0" summary="Method Summary table, listing methods, and an explanation"> -<caption><span id="t0" class="activeTableTab"><span>All Methods</span><span class="tabEnd"> </span></span><span id="t2" class="tableTab"><span><a href="javascript:show(2);">Instance Methods</a></span><span class="tabEnd"> </span></span><span id="t4" class="tableTab"><span><a href="javascript:show(8);">Concrete Methods</a></span><span class="tabEnd"> </span></span></caption> -<tr> -<th class="colFirst" scope="col">Modifier and Type</th> -<th class="colLast" scope="col">Method and Description</th> -</tr> -<tr id="i0" class="altColor"> -<td class="colFirst"><code>boolean</code></td> -<td class="colLast"><code><span class="memberNameLink"><a href="../../../jcgp/backend/population/Chromosome.html#compareActiveGenesTo-jcgp.backend.population.Chromosome-">compareActiveGenesTo</a></span>(<a href="../../../jcgp/backend/population/Chromosome.html" title="class in jcgp.backend.population">Chromosome</a> chromosome)</code> -<div class="block">Does the same as <code>compareGenesto()</code> but only looks -
