Module Hierarchy

• pygene: pygene is a library for genetic algorithms in python
  • gamete: Implements gametes, which are the result of splitting an organism's genome in two, and are used in the organism's sexual reproduction
  • gene: Implements a collection of gene classes
  • organism: Implements classes for entire organisms
  • population: pygene/population.py - Represents a population of organisms
  • prog: Implements genetic programming organisms
  • xmlio: xmlio.py

Class Hierarchy

• __builtin__.object: The most base type
  • pygene.xmlio.PGXmlMixin: mixin class to support pygene classes serialising themselves to/from xml
    • pygene.gene.BaseGene: Base class from which all the gene classes are derived.
      • pygene.gene.BitGene: Implements a single-bit gene
        • pygene.gene.AndBitGene: Implements a single-bit gene, whose phenotype is the AND of each gene in the pair
        • pygene.gene.OrBitGene: Implements a single-bit gene, whose phenotype is the OR of each gene in the pair
        • pygene.gene.XorBitGene: Implements a single-bit gene, whose phenotype is the exclusive-or of each gene in the pair
      • pygene.gene.CharGene: Gene that holds a single ASCII character, as a 1-byte string
        • pygene.gene.AsciiCharGene: Specialisation of CharGene that can only hold chars in the legal ASCII range
          • pygene.gene.PrintableCharGene: Specialisation of AsciiCharGene that can only hold printable chars
      • pygene.gene.ComplexGene: A gene whose value is a complex point number
      • pygene.gene.DiscreteGene: Gene type with a fixed set of possible values, typically strings
      • pygene.gene.FloatGene: A gene whose value is a floating point number
        • pygene.gene.FloatGeneMax: phenotype of this gene is the greater of the values in the gene pair
        • pygene.gene.FloatGeneRandom: Variant of FloatGene where mutation always randomises the value
      • pygene.gene.IntGene: Implements a gene whose values are ints, constrained within the randMin,randMax range
    • pygene.organism.BaseOrganism: Base class for genetic algo and genetic programming organisms
      • pygene.organism.MendelOrganism: Classical Mendelian genetic organism
      • pygene.organism.Organism: Simple genetic algorithms organism
      • pygene.prog.ProgOrganism: Implements an organism for genetic programming
    • pygene.gamete.Gamete: Contains a set of genes.
    • pygene.population.Population: Represents a population of organisms
  • __builtin__.type: type(object) -> the object's type type(name, bases, dict) -> a new type
    • pygene.prog.ProgOrganismMetaclass: a metaclass which analyses class attribs of a ProgOrganism subclass, and builds the list of functions and terminals
• pygene.prog.BaseNode: Base class for genetic programming nodes
  • pygene.prog.FuncNode: node which holds a function and its argument nodes
