I have a problem i assume to be infeasible and use Cbc to "prove" that. I got two questions about this usecase.
I know that Cbc supports online estimation of tree size which could be used to give an estimate of progress of proving infeasibility. Is there a way to output a metric to similar effect using a Cbc_setParameter call?
What solver setting (Cbc_setParameter) would you recommend for infeasible problems to arrive at a proof of infeasibility faster?
processed model has 5128 rows, 912 columns (912 integer (912 of which binary)) and 21648 elements
