Method Detail

acquireChromosome

public Chromosome acquireChromosome()

Attempts to acquire an Chromosome instance from the chromosome pool. It should be noted that nothing is guaranteed about the value of the Chromosome's genes and they should be treated as undefined.

Returns:

A Chromosome instance from the pool or null if no Chromosome instances are available in the pool.

releaseChromosome

public void releaseChromosome(Chromosome a_chromosome)

Releases a Chromosome to the pool. It's not required that the Chromosome originated from the pool--any Chromosome can be released to it. This method will invoke the cleanup() method on each of the Chromosome's genes prior to adding it back to the pool.

Parameters:

a_chromosome - The Chromosome instance to be released into the pool.
