Introduction

A simple and easy-to-use implementation of a Genetic Algorithm library in Python.

pyeasyga provides a simple interface to the power of Genetic Algorithms (GAs). You don’t have to have expert GA knowledge in order to use it.

• Modified the GeneticAlgorithm class initialisation parameters
• Made changes to USAGE documentation
• Added EXAMPLE documentation as a separate section

v0.2.4

2014-07-07

• Refactored most of the code; Made GeneticAlgorithm class more OOP
• Made changes to INSTALLATION documentation

v0.2.3

2014-07-05

v0.2.2

2014-07-05

• Added link to jeffknupp’s sandman repo in HISTORY
• Modified release option in Makefile to also upload project documentation
• Added INSTALLATION and EXAMPLE sections to README.rst
• Removed easy_install installation step from documentation (pip is sufficient)
• Added a simple example of usage to docs/usage.rst
• Reduced the default GA population and generation size (to allow applications that use the different parameters to run quickly)
• Modified tests to account for the new default population, generation size
• Added docstrings to all methods

v0.2.0

2014-07-04

• First upload to pypi.
• Added changes made to HISTORY (pypi upload, new version)

v0.1.0

2014-06-23

• Start of pyeasyga development.

2014-07-03

• Implemented all of basic GA functionality

• Fix issue with odd-numbered population that causes an off-by-one error in the population size

• Set default ga selection function to tournament_selection

• Created examples to show how to use the library

• Start versioning (better late than never); copied jeffknupp’s update_version.sh from sandman

  selected versioning standard: major.minor.micro (e.g. 2.1.5)

  • major => big changes that can break compatibility
  • minor => new features
  • micro => bug fixes
