I found out the solution after a bit of diving into the documentation. I btw still think the default should be to have a random seed as I think that is what most people would expect (I did, but after running a function for a day and night, I found out I was wrong). But anyway, it ultimately comes down to preference, so most important I think is if the user has a clear choice available in both the gui and on the command line. If that could be implemented, either way, that would be great. > -- > Glynn Clements <gl...@gclements.plus.com> >
