Project Summary

Analyzed about 2 years ago based on code collected over 4 years ago.

PyevolveDescriptionThis project focus on development of a complete cross-platform (Windows, Linux) framework for Genetic Algorithms in pure python.

The project is in active development, and I'm doing great efforts to release a good version and documentation soon.

Main features: Many selector algorithms like: Rank Selector Uniform Selector Roulette Wheel Selector Tournament Selector Pure python, you can use in any platform which runs python; Easy to use, easy for end-user; Simple to customize Create new representations, genetic operators;

News 05/08/2008 Added documentation to the code; Created API Docs.

04/08/2008 I've created a Tutorial.

31/07/2008 Released Pyevolve 0.3 (changes in ChangeLogVersion03)!

29/06/2008 Good news, Pyevolve was figured in the "10 Must-Have Python Packages for Social Scientists" !

25/01/2008 Released Pyevolve 0.2 (changes in ChangeLogVersion02)!

Some code example (SimpleCodeExample)from pyevolve import G1DList
from pyevolve import GSimpleGA
from pyevolve import Selectors

def eval_func(ind):
score = 0.0
for x in range(0,len(ind)):
if ind[x]==0: score += 0.1
return score

# Genome instance
genome = G1DList.G1DList(7)
genome.setInitParams(rangemin=0, rangemax=6)

# The evaluator function (objective function)
genome.evaluator.set(eval_func)

# Genetic Algorithm Instance
ga = GSimpleGA.GSimpleGA(genome)
ga.selector.set(Selectors.GRouletteWheel)

# Do the evolution
ga.evolve()

# Best individual
print ga.bestIndividual()
And the result:

- GenomeBase
Evaluated: True
Score: 0.70
Fitness: 0.70
