Algorithm::Evolutionary::Individual::String
Bitstring Individual for a Genetic Algorithm. Used, for instance, in a canonical GA
Creates a new random bitstring individual, with fixed initial length, and uniform distribution of bits. Options as in Algorithm::Evolutionary::Individual::String
Similar to a copy ctor; creates a bitstring individual from a string. Will be deprecated soon
Sets values of an individual; takes a hash as input. Keys are prepended an underscore and turn into instance variables
Decodes to a vector, each one of whose components ranges between $min and $max. Returns that vector
