Hi! I´m doing a MINLP model to minimize water punmping systems, and i
use 2 loop´s in it.
The problem comes when i try tu use GDX utilities to write the several
solutions to a xls file,
because it only write the last solution.

Can someone help?

Thank´s

If you are only getting one solution, it is most likely due to the
placement of your statement in (or outside) of your loops. Perhaps
post a copy of your code, then we might solve it together.

I had a similar problem once, and it turned out that it wasn’t so much
the loop that was causing the problem, but rather that I was always
overwriting my data, which meant I was always stuck with the last
solution. In this case I advise to include a counter in your loop, and
generate new sheets each time, ensuring that your solutions are on
different worksheets (or you can do it with workfiles too).
