Mutation operator for a GA: applies gaussian mutation to a number
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 0.1.
Called create to distinguish from the classwide ctor, new. It just makes simpler to create a Mutation Operator
Sets the instance variables. Takes a ref-to-hash as input
Applies mutation operator to a ``Chromosome'', a vector of stuff,
really. Can be applied only to victims with the _array instance
variable; but it checks before application that both operands are of
type VectorIndi.
Prints as XML, following the EvoSpec 0.2 XML specification. Should be called from derived classes, not by itself.
