genetic algorithms package for python ?

[Xiao Jianfeng]

Hi all,

I am looking for a genetic algorithms package for Python.

I have googled the web before posting and found some links. The link of  
pygene(http://www.freenet.org.nz/python/pygene) cannot be opened.

I also tried the recipe on ASPN, but it is too simple for my 
application, and the ga model in SciPy, which is in testing in the 
"sandbox".

Are there any more genetic algorithms packages for Python ?

Thanks a lot!
