Operator
Class Initialiser

java.lang.Object
  Operator.OperatorModule
      Operator.SourceModule
          Operator.Initialiser

All Implemented Interfaces:

Creator, Module, Operator, ParameterI, Stochastic

Direct Known Subclasses:

RampedHalfAndHalfInitialiser

public class Initialiser
extends SourceModule
implements Creator

Initialiser has a CreationOperation and is used to create a population. The population is created by init(). perform() calls the operation to add codons to the population. The constructor calls createIndividual() to generate a population.
