java.lang.Objectec.Individual
ec.rule.RuleIndividual
public class RuleIndividual
RuleIndividual is an Individual with an array of RuleSets, each of which is a set of Rules. RuleIndividuals belong to some subclass of RuleSpecies (or just RuleSpecies itself).
RuleIndividuals really have basically one parameter: the number of RuleSets to use. This is determined by the num-rulesets parameter.
From ec.Individual:
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 Rulesets. If you add instance variables to a RuleIndividual or subclass, you'll need to read/write those variables as well.
Parameters
base.num-rulesets int >= 1 |
(number of rulesets used) |
base.ruleset.n Classname, subclass of or = ec.rule.RuleSet |
(class of ruleset n) |
Parameter bases
base.ruleset.n | RuleSet n |

java.lang.Object |
clone()
Creates a new individual cloned from a prototype, and suitable to begin use in its own evolutionary context. |
Parameter |
defaultBase()
Returns the default base for this prototype. |
boolean |
equals(java.lang.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. |
void |
parseGenotype(EvolutionState state,
java.io.LineNumberReader reader)
Overridden for the RuleIndividual genotype. |
void |
postprocessIndividual(EvolutionState state,
int thread)
Called by pipelines after they've modified the individual and it might need to be "fixed" -- basically a hook for you to override. |
void |
preprocessIndividual(EvolutionState state,
int thread)
Called by pipelines before they've modified the individual and it might need to be "fixed" -- basically a hook for you to override. |
void |
printIndividual(EvolutionState state,
int log,
int verbosity)
Overridden for the RuleIndividual genotype, writing each ruleset in turn. |
void |
printIndividual(EvolutionState state,
java.io.PrintWriter writer)
Overridden for the RuleIndividual genotype, writing each ruleset in turn. |
void |
printIndividualForHumans(EvolutionState state,
int log,
int verbosity)
Overridden for the RuleIndividual genotype, writing each ruleset in turn. |
void |
readGenotype(EvolutionState state,
java.io.DataInput dataInput)
Overridden for the RuleIndividual genotype. |
void |
reset(EvolutionState state,
int thread)
|
void |
setup(EvolutionState state,
Parameter base)
Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. |
long |
size()
Returns the "size" of the individual. |
void |
writeGenotype(EvolutionState state,
java.io.DataOutput dataOutput)
Overridden for the RuleIndividual genotype, writing each ruleset in turn. |

public java.lang.Object clone()
Prototype
Typically this should be a full "deep" clone. However, you may share certain elements with other objects rather than clone hem, depending on the situation:
Implementations.
public Object clone()
{
try
{
return super.clone();
}
catch ((CloneNotSupportedException e)
{ throw new InternalError(); } // never happens
}
public Object clone()
{
try
{
MyObject myobj = (MyObject) (super.clone());
// put your deep-cloning code here...
}
catch ((CloneNotSupportedException e)
{ throw new InternalError(); } // never happens
return myobj;
}
public Object clone()
{
MyObject myobj = (MyObject) (super.clone());
// put your deep-cloning code here...
return myobj;

Prototype
For prototypes, setup(...) is typically called once for the prototype instance; cloned instances do not receive the setup(...) call. setup(...) may be called more than once; the only guarantee is that it will get called at least once on an instance or some "parent" object from which it was ultimately cloned.
