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
Returns vector size (dimension)
Sets values of an individual; takes a hash as input. The array is initialized to a null array, and the start and end range are initialized by default to 0 and 1
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
Returns a string with chromosome plus fitness. OK, this is a bit confusing
Returns just the chromosome, not the fitness
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++
