Hi experts,

When we solve a LP model by barrier, sometimes it returns solution with NumBest status. My questions are:
1. Is this solution feasible? 
2. Can this solution be used as a feasible & non optimal solution? I know we can further do crossover, but it takes a long time usually, so wondering what risks we might take if we use this solution.

The log of an example:
...
The status is Unknown, the cplex status is NumBest.

Thanks a lot!

Best Regards,

Sophia
