Interface Summary

TraitFactorFitness

This application-specific interface defines how fitness is calculated for a trait value acting with the evironment factor factorVal.

Class Summary

Allele_PepperedMoth	This class defines two alternative instances of Allele via class methods: Allele_PepperedMoth.alleleMelanism() and Allele_PepperedMoth.alleleNoMelanism().
Applet_PepperedMoth	The class which implements the PepperedMoth example applet.
ApplicationDefinitions	This class defines an evolutionary process for a Darwinian System, namely the evolution of the peppered moth.
Census_WingColor	Implementation of Census specifically for the PepperedMoth example and which concentrates on showing the mean wing color (and numbers of organisms with each trait).
ConsoleApplication	Basic main program for running the PepperedMoth example.
ControlPanel_PepperedMoth	A control panel (the lower part of the applet) useful for the peppered moth example.
Environment_PepperedMoth	This class provides an implementation of the Environment interface for the peppered moth example.
Expression_PepperedMoth	Implementation of Expression specifically for the Peppered Moth example.
ExpressionEvaluator_Fitness	Class which knows how to evaluate the wing-color/soot-density fitness
ExpressionEvaluator_MateChoiceDesirability	Class which knows how to evaluate the desirability of a male mate.
ExpressionEvaluator_MateChoiceDesirabilityMinimum	Class which knows how to evaluate the desirability of a male mate.
Factory_PepperedMoth	A specific implementation of Factory for the peppered moth.
Fitness_PepperedMoth	Implementation of Fitness specifically for the peppered moth example.
Individual_PepperedMoth	Class to customize the Individual implementer for the PepperedMoth application.
Locus_PepperedMoth	This application-specific class represents a Locus at which one of several Alleles may appear.
MateChoice_PepperedMoth	Default implementation of MateChoice.
Mutator_PepperedMoth	This mutator is responsible for keeping the carbonaria allele in the population (or, conceivably, the typica allele) Every now and then, the copying of the gene goes wrong and the other allele is used instead.
OptionsPanel_PepperedMoth	Implementation of OptionsPanel_Abstract for the Peppered Moth.
Painter_PepperedMoth	Implementation of Painter for the PepperedMoth example.
PepperedMothEvolution	The main class of the peppered moth solution.
PopulationListener_PepperedMoth	Implementer of PopulationListener which updates a visualization model, and which is specific to the peppered moth application in that it chooses to ignore the control population for display purposes.
Trait_WingColor	Specific implementation of Trait for the peppered moth.
VisualizationFactory_PepperedMoth	Class responsible for creating visualization objects for the PepperedMoth application.
VisualizationModel_PepperedMoth	Visualization Model for the Peppered Moth example.

Peppered Moth Example

The Peppered Moth Example is a biological example and utilizes a sex-based evolutionary mechanism. The genome of the peppered moth is diploid in all organisms. The peppered moth illustrates a very fast adaptation to differing environmental conditions, and was noted and observed during before, during and after the early part of the industrial revolution in Britain. For more information see Wikipedia.
You can run the peppered moth example simply as an applet. Simply click "Start" and watch the moths breed and multiply (each moth is represented by a light or dark grey circle). Now change the sootiness of the environment to a higher value. Watch the ratio of dark moths increase. It may take several generations to react. The options panel (click the left-most tab) allows you to change various settings. You will only be able to change the formulas if you have the JEP (or equivalent) package available in your classpath. See ../expressions/package.html for more details.
