Hi Riley, This condition is not necessary.I changed the type of the variable. M = m.addMVar((p, q), vtype="B", name="M")scalars = m.addMVar((q, p), lb=-float("inf"), name="scalars")e_scalars = m.ad...

Hi Riley, Unfortunately, I found a new problem while doing the tests.I can't deal with it myself but to trouble you again. I'm sorry and your help will be much appreciated! I find that the followin...

Hi Riley, Thank you so much!That might be a good direction to try.I will try to learn Benders Decomposition and use it in gurobi.

Hi Riley, Thank you very much for your reply!I want to explain that I'm using gurobi for cryptanalysis.My optimization goal is to find more rounds of attack routes.In my demo,there are only two rou...

Hi Riley, I'm sorry to ask you again.Like you mentioned above，when I embedding this code in a larger model，I need  add other object.But this affects the minimization of e_borrowed,so I wonder if th...

Thanks for your reply！I upgrade Gurobi and get the right result.

Actually,this line always have an error  m.addConstr((e_borrowed == 0) >> (e_scalars.transpose()==0)) File "src\gurobipy\model.pxi", line 3623, in gurobipy.Model.addConstr  File "src\gurobipy\mline...
