[SCIP] Clique cuts at root node

Hello SCIP team,


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?


I've attached the file with the parameters that I'm using and the output log.

Thanks in advance,
Samuel
