I'll create the file client/ai/genetic.c.
In the meantime, could you send me your account name on SourceForge?
I'll need that in order to be able to grant you write access to the
repository so that you'll be able to post your progress.
I've set the reply to this mail to the mailing list.
With kind regards,
Roland Clobus

Which workflow is chosen depends on personal taste and available time.
At this moment I have much time available, but that might change at any
time.

Whenever you have code that is ready to commit, please do so.
As long as it compiles without errors, you could also commit and use the
commit as a kind of 'remote backup'. It that case nothing will be lost
when disasters happen
