Hello,
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.
Bye,
Denis Sbragion
seems to be fixed in trunk.
