Algorithm::Evolutionary::Op::IncMutation - Increments/decrements by one the value of one of the components of the string, takes into account the char class

Mutation operator for a GA; changes a single element in a string by changing it to the next in the sequence deducted from the chromosome itself.
Creates a new mutation operator.
apply( $indiv )
Applies mutation operator to a "Chromosome", a string, really. Can be applied only to victims with the
_str instance variable; but it checks before application that both operands are of the required type. The chosen character is changed to the next or previous in the array of chars used for coding the the string my $strChrom = new Algorithm::Evolutionary::Individual::String ['a','c','g','t'] 10; my $xmen = new Algorithm::Evolutionary::Op::IncMutation; $xmen->apply( $strChrom ) # will change 'acgt' into 'aagt' or # 'aggt', for instance
Issues an error if there is no
_chars array, which is needed for computing the next.
