Dear members of the Ipopt mailing list,<br>
<br>
I'm quite new to the C++ interface to Ipopt (and sIpopt), so this
question might be trivial. So far I have only used Ipopt through the
CasADi interface.<br>
<br>
In the sIpopt example<br>

Lines 187, 188<br>
I discovered factors 0.5 for the multiplier part of Lagrangian
Hessian. Looking at the KKT system (27) in<br>

I cannot find these factors. Are they required by convention for the
C++ interface?<br>
<br>
Thanks.<br>
<br>
Kind regards,<br>
