Enclosing class:

Population<T extends Chromosome>

public final class Population.Statistics
extends java.lang.Object

The Population.Statistics class is only responsible for storing statistics about a population. As each population can contains legal and illegal individials, it holds the individuals with the higher and lower fitness (a deep-cloning is maked to store these individuals so they don't change if the source population does), the average and deviation values both regard legal individuals and illegal ones. Esamples of use are showed below.

 Population.Statistics stat = a_population.getStatistics();
 

returns a new statistics object setted according to the specified population state.

 Population.Statistics stat = new Population.Statistics();
 a_population.updateStatistics(stat);
 

modifies the existing statistics according to the specified population state.
