Overview

Constant Summary

@@shortener =

Operator::Shorten.new

Instance Attribute Summary (collapse)

• - (Object) complexity readonly

  The complexity of the expression.

• - (Object) genotype readonly

  Genotype vector (array of codons) as provided by the constructor.

• - (Object) phenotype readonly

  Phenotype text (string representing typically the source of the program), the result of GP mapping.

• - (Object) track_support readonly

  The LHS crossover support from the Mapper::Base (see Operator::CrossoverLHS).

• - (Object) used_length readonly

  The number of codons used in the mapping process (see Mapper::Base#used_length).

Instance Method Summary (collapse)

• - (Individual) initialize(mapper, genotype) constructor

  Create the new phenotype, based on the genotype, using the mapper.

• - (Object) shorten_chromozome=(shorten)

  If set to true, the genome is shortened by the Shorten#shorten with the used_length argument.

• - (Boolean) valid?

  Return true if the phenotype is valid (the mapping process was succesful).
