<hr><a name="_details"></a><h2>Detailed Description</h2>
This class is interface for selection operation which selects chromosomes from population which are going to be used as parents in production of new chromosomes.
<p>
This class has no built-in synchronizator, so <code>LOCK_OBJECT</code> and <code>LOCK_THIS_OBJECT</code> macros cannot be used with instances of this class. No public or private methods are thread-safe. <hr><h2>Member Function Documentation</h2>
