Algorithm::Evolutionary::Op::CX (Cycle crossover) - 2-point crossover operator; Builds offspreing in such a way
that each gene comes from one of the parents. Preserves the absolute position of the elements
in the parent sequence

Algorithm::Evolutionary::Op::Base
Cycle Crossover operator for a GA. It applies to chromosomes that are a permutation of each other; even as the class it applies to is the Algorithm::Evolutionary::Individual::Vector manpage, it will issue lots of ``La jodimos!'' messages if the parents do not fulfill this condition.
Some information on this operator can be obtained from http://www.cs.bham.ac.uk/~rmp/slide_book/node4.html#SECTION00444300000000000000|this evolutionary computation tutorial
Creates a new Algorithm::Evolutionary::Op::CX operator.
Creates a new Algorithm::Evolutionary::Op::CX operator. But this is just to have a non-empty chromosome
Applies Algorithm::Evolutionary::Op::CX operator to a ``Chromosome'', a bitstring, really. Can be
applied only to victims with the _bitstring instance variable; but
it checks before application that both operands are of type
Algorithm::Evolutionary::Individual::Vector.
