<p>Hi Marcus,<o:p></o:p></p>
<p><o:p> </o:p></p>
<p>try to display the statistics of SCIP. The source of the cuts could be a separator or a constraint handler. In the statistics you will see how many cuts are added by separators and constraint handlers.<o:p></o:p></p>
<p><o:p> </o:p></p>
<p>The statistics can be printed in the command line with "display statistics" and in the callable library with SCIPprintStatistics().<o:p></o:p></p>

<p>Best,<br>
