Discrepancy between versions 8.2 and 7.5 #2468
-
|
Helllo @lperron and everyone, I believe there is a possible bug in the presolve as the attached model is infeasible in version 8.2 but feasible in 7.5! I think 7.5 is correct as at least 0 should be a feasible in this case. Interestingly, the model is infeasible from version 7.6 onwards so I believe it has been there for some time. Any help or advice you can offer will be appreciated. I am using python interface. |
