<p>Hello Samuel,</p>
<p>SCIP usually finds cliques during presolving, which you turned
off. Therefore the clique separator has no cliques to work with
and cannot find cuts.<br>

<pre style="white-space:pre-wrap;color:rgb(0,0,0)">
I have developed a clique cut separation routine and I'm interested in comparing this approach with the one provided by SCIP.
For this, I'm trying to separate and insert clique cuts at the root node and investigate the improvement of the dual bound.
I have turned off the presolving, heuristics and all other types of cuts. Also, I have set the maximum number of nodes to 1.
However, the clique cut separator of SCIP is not generating any cut.
Is there another way to do this?</pre>
<pre style="white-space:pre-wrap;color:rgb(0,0,0)">
I've attached the file with the parameters that I'm using and the output log.
Thanks in advance,
Samuel
