Constructor Detail

MutateVertex

public MutateVertex(VertexAndEdgeProvider p)
Method Detail

makeChild

public Graph makeChild(Graph child)
Returns:
parameter graph mutated. No new graph created.

numberOfParents

public int numberOfParents()
Overrides:
numberOfParents in class ChildMaker
Returns:
1

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()
