Hi Matthias Thanks for the clarification. For some reasons, I am not able to recover the solution to the original model by using the extracted data from the model. Here is a pseudo code: A = model....

Hi Matthias May I ask if the A, and RHS matrix/vectors provided by getA(), RHS = model.getAttr('RHS'), already includes the bound constraints l ≤ x ≤ u (bound constraints) or they need to be impos...

Find redundant constraint in MILP
回答済みHi I understand that there are some sophisticated methods used in presolve to reduce the size of a model. To the best of my knowledge, the algorithm in presolve comes up with a reduced model and a ...

Hi Mathias Thanks for your comments. Something which is very strange is that if I call getAttr() codes before calling getA() the results is empty (for all) but if I them after getA(), I get the cor...

Solver input matrices for MILP
回答済みIs there a way to get the final A, b, c, u, l matrices/vectors which are the results of a MILP model? Say for example you model the unit commitment problem as done here. Is there a way to get the c...
