Welcome to Pyevolve documentation !¶
“We can allow satellites, planets, suns, universe, nay whole systems of universe, to be governed by laws, but the smallest insect, we wish to be created at once by special act.“
- Charles R. Darwin, 1838
Pyevolve was developed to be a complete genetic algorithm framework written in pure python, but since the version 0.6, the framework is also supporting Genetic Programming, so in the near future, the framework will be more an Evolutionary Computation framework than a simple GA framework.
See the changes in the What’s new ? section of this documentation.
This is the documentation for the release v.0.6rc1.
See some plot screenshots on the Graph Types and Screenshots section.
You can download this manual also in other formats:
