Hi,<br>
<br>
the CONOPT manual has some nice documentation on how to scale an NLP:<br>
<a href="http://www.gams.com/dd/docs/solvers/conopt.pdf" target="_blank">http://www.gams.com/dd/docs/<u></u>solvers/conopt.pdf</a><br>
I believe it can be applied to Ipopt as well.<br>

Hello,<br>
<br>
I would like to scale my non linear problem and thus improve my optimizer's<br>
overall performance (since right now I'm getting a lot of messages like<br>
this "In iteration 419, 1 Slack too small, adjusting variable bound"). I<br>
tried to find help both in the documentation and online, but unfortunately<br>
I didn't find any useful tutorial/how to related to tuning this parameter.<br>
Any help would be very appreciated.<br>
<br>
Thanks in advance,<br>
<br>
Alessandro<br>
