Constructor Detail

ChildMaker

public ChildMaker()
Method Detail

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()

toString

public java.lang.String toString()
Overrides:
toString in class ChildMaker
