NAME

    GPIndi - Array as an individual for evolutionary computation

SYNOPSIS #Hash with primitives and arity. my $primitives = { sum => 2, multiply => 2, substract => 2, divide => 2, x => 0, y => 0 };

    my $indi = new GPIndi $primitives, 5 ; # Build random tree with knwo primitives
                                           # and depth up to 5
    my $indi5 = $indi->clone(); #Creates a copy of the individual
    print $indi3->asString(); #Prints the individual
    print $indi3->asXML() #Prints it as XML. See L<XML> for more info on this

Base Class

IndiBase

DESCRIPTION

Array individual for a genetic programming. Uses Direct Acyclic graphs as representation for trees, which is very convenient.

new

Creates a new random array individual, with fixed initial length, and uniform distribution of values within a range

set

Sets values of an individual; takes a hash as input

randomize

Assigns random values to the elements

fromString

Similar to a copy ctor; creates a bitstring individual from a string composed of stuff separated by a separator

clone

Similar to a copy ctor: creates a new individual from another one

asString

Prints it

asXML

Prints it as XML. See the XML OPEAL manual for details.

lolprint

Print the list of lists that composes the tree, using prefix notation

growSubTree

Grows a random tree, with primitives as indicated, and a certain depth. Depth defaults to 4
