Subject [jira] Updated: (MATH-207) Implementation of GeneticAlgorithm.nextGeneration() is wrong
Date Mon, 29 Sep 2008 11:06:44 GMT

David Stefka updated MATH-207:
------------------------------

    Attachment: genetics_impl.zip

Dear Phil,

if you are interested in the topic of genetic algorithms, I am sending a 
simple implementation of GA using the commons-math framework. If you find any 
of the ideas in it useful, you may use it.

Best regards,
David Stefka
