A solver for mixed integer bilevel programs
Hi, I wonder if I'm using the solver the wrong way... My problem has four upper level feasible solutions. If necessary I can generate and share the bilevel feasible solutions...
Hello, I am trying to build a minimal example for using MibS with C++. # Context I am trying to model the following problem using the C++ API: ``` min...
- Update Interdiction type problem data reading in `MibSModel`; - Update two Benders cuts to reflect the changes in MibS valid inequality paper; - Add a fractional cut option to...
[Julia_Model_MibS.txt](https://github.com/coin-or/MibS/files/13635090/Julia_Model_MibS.txt) Hello, I am a student at the University of Siegen. I am using the MibS solver for my Master's thesis. However, I trouble with the Julia model in the...
Hi, I am currently trying to use MibS and I am not able to get it to work. It seems like my upper level variables are not detected, this output...
Dear MibS-Team, thanks for the development and maintaining of MibS! By using MibS I face the problem, that no solution files can be retrieved, and after displaying > Branching strategy...
I found this very weird behavior on one instance that I wanted to share with you. When I solve the problem with the auxiliary file presenting the follower as maximization...
Hi, When I executed the MibS, I got the following error message. The platform is MacOS X and paths are already added to .bashrc. When I check the lib, I...
The main changes in this draft: - add gaps to related functions in UB problems setup and cut generations; - add pessimistic related parameters and variables; add containers and tags...
