Method Detail

operate

public abstract java.util.List<ExampleSetBasedIndividual> operate(ExampleSetBasedIndividual individual)
                                                           throws java.lang.Exception

Subclasses must implement this method providing a list of new individuals. individual will be removed from the population so it might be useful to return a list of size 1 containing only the modified individual. If the original individual should also be part of the new population it must also be added to the result list.

Throws:

java.lang.Exception

operate

public void operate(ExampleSetBasedPopulation pop)
             throws java.lang.Exception
