All Implemented Interfaces:

Serializable, Population, MLInput, MLInputOutput, MLMethod, MLOutput, MLProperties, MLRegression

public class PrgPopulation
extends BasicPopulation
implements MLRegression

A population that contains EncogProgram's. The primary difference between this class and BasicPopulation is that a "compute" method is provided that automatically uses the "best" genome to provide a MLRegression compute method. This population type also holds the common context that all of the EncogProgram genomes make use of.
