This file defines several different genotype (aka genome, chromosomes) classes. Inherit from one of these classes and define a fitness function to use them.

Public Instance methods

BitStringGenotype(n)

Genotype of n bits. Individuals are initialized as an array of n random bits.

    # File lib/charlie/list/list_genotype.rb, line 26
26: def BitStringGenotype(n)
27:  Class.new(Genotype) {
28:   [self,metaclass].each{|c| c.class_eval{ # include both in class and metaclass

36:   end
37:   use ListMutator(:expected_n,:flip), SinglePointCrossover.dup
38:  }
39: end
FloatListGenotype(n,range=0..1)

Genotype of n floats in the range range. Individuals are initialized as an array of n random numbers in this range. Note that mutations may cross range min/max.

    # File lib/charlie/list/list_genotype.rb, line 8

10:   @@range = range

16:   end
17:   def to_s
18:     @genes.inspect
19:   end
20:   use ListMutator(), SinglePointCrossover.dup
21:  }
22: end
StringGenotype(n,elements)

Genotype of n elements (not necessarily chars). Individuals are initialized as an array of n elements, each randomly chosen from the elements array.

[Source]

    # File lib/charlie/list/list_genotype.rb, line 43
43: def StringGenotype(n,elements)
44:  elements = elements.chars if elements.is_a? String # string to array of chars
45:  elements = elements.to_a
46:  Class.new(Genotype) {
47:   [self,metaclass].each{|c| c.class_eval{ # include both in class and metaclass
48:    define_method(:size){ n }
49:    define_method(:elements){ elements }

54:   def to_s
55:     @genes.map(&:to_s).join
56:   end
57:   use ListMutator(:expected_n[2],:replace[*elements]), SinglePointCrossover.dup
58:  }
59: end
