public class GPIndividual extends Individual
GPIndividuals have two clone methods: clone() and lightClone(). clone() is a deep clone method as usual. lightClone() is a light clone which does not copy the trees.
In addition to serialization for checkpointing, Individuals may read and write themselves to streams in three ways.
In general, the various readers and writers do three things: they tell the Fitness to read/write itself, they read/write the evaluated flag, and they read/write the GPTree array (by having each GPTree read/write itself). If you add instance variables to GPIndividual, you'll need to read/write those variables as well.

Modifier and Type | Method and Description |
---|---|
Object |
clone()
Deep-clones the GPIndividual.
|
Parameter |
defaultBase()
Returns the default base for this prototype.
|
boolean |
equals(Object ind)
Returns true if I am genetically "equal" to ind.
|
int |
hashCode()
Returns a hashcode for the individual, such that individuals which
are equals(...) each other always return the same
hash code.
|
GPIndividual |
lightClone()
Like clone(), but doesn't force the GPTrees to deep-clone themselves.
|
void |
parseGenotype(EvolutionState state,
LineNumberReader reader)
This method is used only by the default version of readIndividual(state,reader),
and it is intended to be overridden to parse in that part of the individual that
was outputted in the genotypeToString() method.
|
void |
printIndividual(EvolutionState state,
int log)
Should print the individual in a way that can be read by computer,
including its fitness, with a verbosity of Output.V_NO_GENERAL.
|
void |
printIndividual(EvolutionState state,
PrintWriter writer)
Should print the individual in a way that can be read by computer,
including its fitness.
|
void |
printIndividualForHumans(EvolutionState state,
int log)
Should print the individual out in a pleasing way for humans,
with a verbosity of Output.V_NO_GENERAL.
|
void |
printTrees(EvolutionState state,
int log)
Prints just the trees of the GPIndividual.
|
void |
readGenotype(EvolutionState state,
DataInput dataInput)
Overridden for the GPIndividual genotype.
|
void |
setup(EvolutionState state,
Parameter base)
Sets up a prototypical GPIndividual with those features which it
shares with other GPIndividuals in its species, and nothing more.
|
long |
size()
Returns the "size" of the individual, namely, the number of nodes
in all of its subtrees.
|
void |
verify(EvolutionState state)
Verification of validity of the GPIndividual -- strictly for debugging purposes only
|
void |
writeGenotype(EvolutionState state,
DataOutput dataOutput)
Overridden for the GPIndividual genotype.

Individual
The default form of this method simply prints out whether or not the individual has been evaluated, its fitness, and then calls Individual.genotypeToString(). Feel free to override this to produce more sophisticated behavior, though it is rare to need to -- instead you could just override genotypeToString().
