Hi Istvan,
Yes. I tested it and found out that it's behaving as expected, though the algorithm seems to do a final coordinate adjustment at the end of each XMIN computation. Thus, the coordinates reported at each step don't correspond to the energies; that's just something we have to be aware of, I think.
Thanks for following up!
Regards,
Ben
