Hello everybody,
I cannot resolve the following problem:
Sometimes during solving my MIPs by branch and price I get SCIP_RETCODE
of -6 and the whole MIP is stopped.
The same can happen during probing, if I take a perfectly feasible
fractional solution, start probing, fix one variable to 1 (which is
always feasible) and solve the probing LP.
Has anybody had the same problem before?
Regards,
Frank
