Mutation operator for a GA; changes a single element in a string
Creates a new mutation operator.
Sets the instance variables. Takes a ref-to-hash as input
Applies mutation operator to a ``Chromosome'', a bitstring, really. Can be
applied only to victims with the
_str instance variable; but
it checks before application that both operands are of type
Prints as XML, following the EvoSpec 0.2 XML specification. Should be called from derived classes, not by itself.
