NAME
Algorithm::Evolutionary::Individual::String - A character string to be evolved. Useful mainly in word games
SYNOPSIS
use Algorithm::Evolutionary::Individual::String;
my $indi = new Algorithm::Evolutionary::Individual::String ['a'..'z'], 10;
# Build random bitstring with length 10
my $indi3 = new Algorithm::Evolutionary::Individual::String;
$indi3->set( { length => 20,
chars => ['A'..'Z'] } ); #Sets values, but does not build the string
$indi3->randomize(); #Creates a random bitstring with length as above
print $indi3->Atom( 7 ); #Returns the value of the 7th character
$indi3->Atom( 3, 'Q' ); #Sets the value
$indi3->addAtom( 'K' ); #Adds a new character to the bitstring at the end
my $indi4 = Algorithm::Evolutionary::Individual::String->fromString( 'esto es un string'); #Creates an individual from that string
my $indi5 = $indi4->clone(); #Creates a copy of the individual
my @array = qw( a x q W z ñ); #Tie a String individual
tie my @vector, 'Algorithm::Evolutionary::Individual::String', @array;
print $indi3->as_string(); #Prints the individual
Base Class
Algorithm::Evolutionary::Individual::BaseDESCRIPTION
String Individual for a evolutionary algorithm. Contains methods to handle strings easily. It is also TIEd so that strings can be handled as arrays.METHODS
MY_OPERATORS
Known operators that act on this subroutine. Probably will be deprecated, so don't rely on its presencenew
Creates a new random string, with fixed initial length, and uniform distribution of characters along the character class that is defined. However, this character class is just used to generate new individuals and in mutation operators, and the validity is not enforced unless the client class does itrandomize
Assigns random values to the elementsaddAtom
Adds an atom at the endfromString
Similar to a copy ctor; creates a bitstring individual from a string. Will be deprecated soonfrom_string
Similar to a copy ctor; creates a bitstring individual from a string.clone
Similar to a copy ctor: creates a new individual from another oneasString
Returns the individual as a string with the fitness as a suffix.Atom
Sets or gets the value of the n-th character in the string. Counting starts at 0, as usual in Perl arrays.TIE methods
String implements FETCH, STORE, PUSH and the rest, so an String can be tied to an array and used as such.size()
Returns length of the string that stores the info; overloads abstract base method.as_string()
Returns the string used as internal representation
Chrom
Sets or gets the variable that holds the chromosome. Not very nice, and I would never ever do this in C++Known subclasses
