Hi Nguyen,The numerical stability of your model is mostly affected by the conditioning of matrices involved in linear systems of equations, e.g., basis matrices in the simplex algorithm. In case of...

Hi Songping,I went ahead and created a ticket so we can investigate this further.Best regards,Vassilios

Hi,Is the CPX_PARAM_SOLNPOOLINTESITY setting of 4, documentation here: https://www.ibm.com/docs/en/icos/22.1.0?topic=parameters-solution-pool-intensity same as setting PoolSearchMode setting in Gur...

Hi,In this case a solution would be accepted and the lazy constraint would not be added to the cut pool. This should also not result in an infinite loop, since the same solution would not be found ...

Hi Junseo,I went through the first sections of the paper you linked and here are some comments:  Does GUROBI gaurantee finding all possible solutions for ILP?No, this is technically not guaranteed...

Hi Felipe, I just wanted to inform you, that in the upcoming release of Gurobi (v. 12) it will be possible to query the ObjBound after an LP is solved with Barrier without Crossover, or if the solu...

Hi Andreas, We have opened a support ticket to better track your feature request and to further discuss the issue. Best regards, Vassilios
