gov.nasa.javaGenes.core.ChildMakerChain
- All Implemented Interfaces:
- java.lang.Cloneable, java.io.Serializable
- public class ChildMakerChain
- extends ChildMaker
probabalistically mutates the children of a ChildMaker. Can chain mutators for an unlimited length.

ChildMakerChain
public ChildMakerChain(ChildMaker childMaker)
addMutator
public void addMutator(ChildMaker mutator,
double probability)
- mutator must take one parent only
numberOfParents
public int numberOfParents()
- Overrides:
numberOfParents
in class ChildMaker
- Returns:
- the number of parents makeChildren expects. I.e., the length of the
array passed to makeChildren. If not implemented by subclass, defaults to 1 (mutation).
makeChildren
public Evolvable[] makeChildren(Evolvable[] parents)
- Description copied from class:
ChildMaker
- Defaults to mutation, any subclass wanting more than one parent must over-ride. Mutators can over-ride mutate(Evovlable)
- Overrides:
makeChildren
in class ChildMaker
- Parameters:
parents
- the evolvables from which children will be created. By convention, the parents are not modified.
- Returns:
- the children created. Subclass must implement copyForEvolution()
getFromChain
protected ChildMakerChain.ChainElement getFromChain(int index)
toString
public java.lang.String toString()
- Overrides:
toString
in class ChildMaker
