Algorithm::Evolutionary::Individual::String - A character string to be evolved. Useful mainly in word games
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 tied( @vector )->asXML(); print $indi3->as_string(); #Prints the individual
Algorithm::Evolutionary::Individual::Base
String Individual for a evolutionary algorithm. Contains methods to handle strings easily. It is also TIEd so that strings can be handled as arrays.
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 it
Assigns random values to the elements
Adds an atom at the end
Similar to a copy ctor; creates a bitstring individual from a string. Will be deprecated soon
Similar to a copy ctor; creates a bitstring individual from a string.
Similar to a copy ctor: creates a new individual from another one
Prints it
Sets or gets the value of the n-th character in the string. Counting starts at 0, as usual in Perl arrays.
String implements FETCH, STORE, PUSH and the rest, so an String can be tied to an array and used as such.
Returns length of the string that stores the info; overloads abstract base method.
Returns the string used as internal representation
Prints it as XML. See Algorithm::Evolutionary::XML for more info on this
Sets or gets the variable that holds the chromosome. Not very nice, and I would never ever do this in C++
