Defines the weight or probability that the subtree mutation method will be chosen over the other genetic programming mutation methods. When mutation is selected to occur (see MutationProbability ), the genetic programming component chooses a mutation method using the weights you supply.

Subtree mutation replaces a randomly selected subtree of the child with a newly genereated subtree. The old subtree is deleted and a new subtree is grown in its place. The new subtree can be of a different type than the one being replaced, e.g., a constant is replaced with a function and its children.
