openGA 0.2.0

genetic algorithm framework

openGA

Overview

Open source genetic algorithm framework. openGA works on Python >= 3.7.

Goals

The main goals for this library are:

• to be convenient to adapt to optimization problems
• to have clean and easy to understand code base
• to have minimal 3-rd party dependencies

Usage

• demo problem Seach optimal x-y combination to get maximal response of objective function. Surface plot of object function:

• theoretical solution

  $$ z = 4.00 \text{, at } x = 0.25, y= 0.25 $$

• openGA solution

  $$ z = 3.99 \text{, at } x = 0.2393, y = 0.2411 $$

  notice: solution will change marginally between each run for random searching machenism.

• openGA searching process Evolve 15 generations with 20 individuals in each iteration.

Check the examples folder for extended usage demo.
