Known Subclasses:: MendelOrganism, Organism, ProgOrganism

Base class for genetic algo and genetic programming organisms

Best not use this directly, but rather use or subclass from one of:

Organism

ProgOrganism

Method Summary
	`__add__(self, partner)` Allows '+' operator for sexual reproduction
	`__cmp__(self, other)` Convenience method which invokes duel
	`__repr__(self)` Delivers a minimal string representation of this organism.
	`duel(self, opponent)` Duels this organism against an opponent
	`dump(self)` Produce a detailed human-readable report on this organism and its structure
	`fitness(self)` Return the fitness level of this organism, as a float
	`mate(self, partner)` Mates this organism with another organism to produce an entirely new organism
	`mutate(self)` Implement the mutation phase
	`xmlDumpAttribs(self, elem)` Dump out the custom attributes of this organism
	`xmlDumpSelf(self, doc, parent)` Dumps out this object's contents into an xml tree
Inherited from PGXmlMixin
	`xmlDump(self, fileobj)` Dumps out the population to an open file in XML format.
	`xmlDumpClass(self, tag)` dumps out class information
	`xmlDumps(self)` dumps out to xml, returning a string of the raw generated xml
Inherited from object
	`__init__(...)` x.__init__(...) initializes x; see x.__class__.__doc__ for signature
	`__delattr__(...)` x.__delattr__('name') <==> del x.name
	`__getattribute__(...)` x.__getattribute__('name') <==> x.name
	`__hash__(x)` x.__hash__() <==> hash(x)
	`__new__(T, S, ...)` T.__new__(S, ...) -> a new object with type S, a subtype of T
	`__reduce__(...)` helper for pickle
	`__reduce_ex__(...)` helper for pickle
	`__setattr__(...)` x.__setattr__('name', value) <==> x.name = value
	`__str__(x)` x.__str__() <==> str(x)

Method Details

add(self, partner)
(Addition operator)

Allows '+' operator for sexual reproduction

Returns a whole new organism object, whose gene pair for each gene name are taken as one gene randomly selected from each parent

cmp(self, other)
(Comparison operator)

Convenience method which invokes duel

Allows lists of organisms to be sorted

repr(self)
(Representation operator)

Delivers a minimal string representation of this organism.

Override if needed

Overrides:: __builtin__.object.__repr__

duel(self, opponent)

Duels this organism against an opponent

Returns -1 if this organism loses, 0 if it's a tie, or 1 if this organism wins

dump(self)

Produce a detailed human-readable report on this organism and its structure

fitness(self)

Return the fitness level of this organism, as a float

Should return a number from 0.0 to infinity, where 0.0 means 'perfect'

Organisms should evolve such that 'fitness' converges to zero.

This method must be overridden

mate(self, partner)

Mates this organism with another organism to produce an entirely new organism

Override this in subclasses

mutate(self)

Implement the mutation phase

Must be overridden

xmlDumpAttribs(self, elem)

Dump out the custom attributes of this organism

elem is an xml.dom.minidom.element object

Overrides:: pygene.xmlio.PGXmlMixin.xmlDumpAttribs

xmlDumpSelf(self, doc, parent)

Dumps out this object's contents into an xml tree

Arguments:

doc - an xml.dom.minidom.Document object
parent - an xml.dom.minidom.Element parent, being the node into which this node should be placed

Overrides:: pygene.xmlio.PGXmlMixin.xmlDumpSelf
