Detailed Description

GaSelectRandom selection is randomly selects defined number of chromosomes. This selection use GaSelectDuplicatesParams class for parameters.

This class has no built-in synchronizator, so LOCK_OBJECT and LOCK_THIS_OBJECT macros cannot be used with instances of this class. Because this genetic operation is stateless all public method are thread-safe.
