Below is a comparison of the codes for both algorithms (comments have been
|
|
removed).
|
|
<br><b><font color="#FF6600">Warning</font></b>: the <font color="#FF6666">pink
|
|
background</font> here denotes the differences, not the section of
|
|
the algorithm, which is only recalled by the color of the text!
|
|
<br>These differences are limited to
|
|
<ul>
|
|
<li>
|
|
the declaration of <font color="#666600">the type of the genotypes,</font></li>
|
|
|
|
<li>
|
|
the <font color="#990000">fitness function</font> (what did you expect
|
|
:-),</li>
|
|
|
|
<li>
|
|
the <font color="#CC33CC">initialization</font> (and if you look carefully,
|
|
you'll find out that only a small part of the initialization is different,
|
|
as both genotypes are eoFixedLength objects) and of course</li>
|
|
|
|
<li>
|
|
the choice of <font color="#CC33CC">variation operators </font>(including
|
|
the parameter for the mutation).</li>
