#186 closed defect (migrated)

Feasible problem reported as infeasible

Reported by: dindy Owned by: tkr
Priority: major Component: Cbc
Version: 2.9.8 Keywords:



the attached problem is reported as infeasible by CBC 2.9.9, even though it is feasible. Command line used is simply:

cbc -import inf.lp -solve -quit

If I set the ratiogap to an high value, say 0.5, a (suboptimal) feasible solution is found.

CBC has been compiled with mingw32 but I tested also with the supplied MSVC precompiled binaries to be sure it isn't just some compilation issue.

Hope it helps, and thanks for this excellent software.
