Hi George,<br>
<br>
does SCIP detect the infeasibility already in presolving? If that is
the case, as a start, you should set the verbosity level in SCIP to
5 (which stands for full). The parameter is called
"display/verblevel", in the interactive shell, type "set disp
verblevel 5". This will give you the information which constraint
handler or other plugin detected the infeasibility.<br>
<br>
After that, we can discuss how to identify the cause for the
infeasibility. For that, it would be good if you sent us the
instance and the SCIP output (best send it to me directly).<br>
<br>
Best,<br>
Gerald<br>

<div dir="ltr">If I am running SCIP on a ZMPL file like "scip -f
blah.zpl" and it determines that my problem is infeasible, is
there any way to also output the potential variables that are
causing the infeasibility? Basically, something to help me
debug the issue.
