Method Detail

operate

public java.util.List<Individual> operate(EvolutionaryAlgorithm algorithm,
                                          java.util.List<Individual> individuals)
                                   throws OperatorException
Description copied from interface: Operator
Execute this operator over a group of individuals. This method will be invoked by the current algorithm during its execution. It will be applied on a list of individuals and will return a list of modified individuals.

This method will recive two parameters. The current algorithm, to visit it if it is necessary, for example, to get some parameter of the current execution. And a list of individuals on wich we will apply this operator.

Specified by:
operate in interface Operator
Parameters:
algorithm - the current algorithm, to visit when it is necessary.
individuals - list of individuals on wich we will apply the operator.
Returns:
the result of apply this operator to a individuals' lisr.
Throws:
OperatorException - when occurs some type of error during the execution of this operator.
