"You should try going through your model variable by variable, constraint by constraint. Check whether the bounds and types of your variables are set correctly" How do I check my model variable by ...

Hi Jaromil, I computed by.IIS method: But as you can see when I am doing m.write("mIIS.ilp"), It is just returning all constraints & not those that are violated.

Hi Jaromil, This is quite stressful to see your algorithm running & not giving the correct output. I am quite stressed. I am trying to do a computeIIS method but it is taking a time. If the constra...

"It is not the objective value. It is the best lower bound that can be proven. Feasible points are listed in the "Incumbent" column" - What is incumbent column? I looked though the basics but here ...

Hi Jaromil, I made sure my constraints are not violated. But there is something unusual happening here. There is an objective function value & still it shows model is infeasible. Can you please tel...

Gurobi has this nice feature of analyzing things. I understood why this is happening. I am trying to resolve it.   [res_cat2idx, res_num] = [OrderedDict([('EAF', [1]), ('AOD', [2...

Can you explain me what the below .lp file means to say? \ Model steel RTN_copy\ LP format - for model browsing. Use MPS format to capture full model detail.Minimize Subject To Transfertime[126,95]...

Ok Jaromil, I got your point. With all your understandings, I checked by writing.lp files after my each constraint.It showed me correct formulations. Now after optimising it, it is showing me infea...

  Price_energy = list(of 96 values for each t) =  [33, 33, 33, 33, 30, 30, 30, 30, 29, 29, 29, 29, 28, 28, 28, 28, 34, 34, 34, 34, 50, 50, 50, 50, 71, 71, 71, 71, 77, 7...

Ok Jaromil, Also can we use two quicksum in an objective function like below? I doubt doing so. reslist2=[]reslist2.append(res_cat2idx['EN'][0])obj=gp.quicksum(price_energy[t] for t in time)*gp.qu...
