Algorithm::Evolutionary::Individual::Base
Array individual for a EA. Generally used for floating-point arrays. It can be also TIEd so that it can be handled as a normal array.
Creates a new random array individual, with fixed initial length, and uniform distribution of values within a range
Sets values of an individual; takes a hash as input
Assigns random values to the elements
Gets or sets the value of an atom
Adds an atom at the end
Returns the number of atoms in the individual
Similar to a copy ctor; creates a vector individual from a string composed of stuff separated by a separator
Similar to a copy ctor: creates a new individual from another one
Prints it
Prints it as XML. See the Algorithm::Evolutionary::XML OPEAL manual for details.
Sets or gets the array that holds the chromosome. Not very nice, and I would never ever do this in C++
