Mutation - BitFlip mutation, changes several bits, depending on the probability
my $op = new Algorithm::Evolutionary::Op::TreeMutation (0.5 ); #Create from scratch
Mutation operator for a genetic programming, mutates tree nodes with a certain probability
Creates a new mutation operator with an application rate. Rate defaults to 0.1.
Creates a new mutation operator with an application rate. Rate defaults to 0.5.
Called create to distinguish from the classwide ctor, new. It just makes simpler to create a Mutation Operator
Applies mutation operator to a ``Chromosome'', but it checks before application that both operands are of type Algorithm::Evolutionary::Individual::Tree.
Callback routine called from apply; decides on mutation application, and applies it. If appliable, substitutes a node by other with the same arity. Builds a lists of nodes before, to speed up operation
