[Ipopt] How to properly scale my problem

[Alessandro Roncone]

Hello,

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

Thanks in advance,

Alessandro
