NAME
       AI::Genetic::OpMutation - A class that implements various mutation
       operators.

SYNOPSIS
       See AI::Genetic.

DESCRIPTION
       This package implements a few mutation mechanisms that can be used in
       user-defined strategies.	The methods in this class are to be called as
       static class methods, rather than instance methods, which means you
       must call them as such:

	 AI::Genetic::OpCrossover::MethodName(arguments)

CLASS METHODS
       There is	really one kind	of mutation operator implemented in this
       class, but it implemented for the three default individuals types. Each
       gene of an individual is	looked at separately to	decide whether it will
       be mutated or not. Mutation is decided based upon the mutation rate (or
       probability). If	a mutation is to happen, then the value	of the gene is
       switched	to some	other possible value.

       For the case of bitvectors, an ON gene switches to an OFF gene.

       For the case of listvectors, a gene's value is replaced by another one
       from the	possible list of values.

       For the case of rangevectors, a gene's value is replaced	by another one
       from the	possible range of integers.

       Thus, there are only three methods:

       bitVector(mut_prob, genes)
	   The method takes as input the mutation rate,	and an anonymous list
	   of genes of a bitvector individual. The return value	is an
	   anonymous list of mutated genes.  Note that it is possible that no
	   mutation will occur,	and thus the returned genes are	identical to
	   the given ones.

       listVector(mut_prob, genes, possibleValues)
	   The method takes as input the mutation rate,	an anonymous list of
	   genes of a listvector individual, and a list	of lists which
	   describe the	possible values	for each gene. The return value	is an
	   anonymous list of mutated genes.  Note that it is possible that no
	   mutation will occur,	and thus the returned genes are	identical to
	   the given ones.

       rangeVector(mut_prob, genes, rangeValues)
	   The method takes as input the mutation rate,	an anonymous list of
	   genes of a rangevector individual, and a list of lists which
	   describe the	range of possible values for each gene.	The return
	   value is an anonymous list of mutated genes.	Note that it is
	   possible that no mutation will occur, and thus the returned genes
	   are identical to the	given ones.
