<div dir="ltr"><pre>Dear All,
I am trying to run Couenne on some .nl files and ipopt has no problems with them, but Couenne does. This is the output I get.
bash-4.1$ ./couenne <a href="http://problem.nl">problem.nl</a><br>Couenne 0.4.8 -- an Open-Source solver for Mixed Integer Nonlinear Optimization<br>Mailing list: <a href="mailto:couenne@list.coin-or.org">couenne@list.coin-or.org</a><br>Instructions: <a href="http://www.coin-or.org/Couenne">http://www.coin-or.org/Couenne</a><br><br>ERROR: unknown operator (address 0p7f25acb37830), aborting.<br><br>Does anyone know what can be the issue and if there are some limitations on what Couenne can solve (and what is already solvable by ipopt)?
Sincerely yours,
Lukasz Segiet</pre></div>
