Hi Jaromil, I have tried doing what was recommended by you,However I dont seem so what is there in steel_feasrelax.lp file.I will write some output here to make you aware. However I feel,I have tri...

Hi Jaromil, I am trying the method you described : The process is still running. I am not sure what is happening here?

Ok Shall I do these for all the remaining constraints to make the model clear? 1. Taskexecution=steel.addConstrs((gp.quicksum(Tasks[task,t] for t in time)==1 for task in heat2tasks),name="Taskexecu...

Ok I am giving you a example: Tranfertime constraint: y={}for res_cat, resources in res_cat2idx.items():        if 'H_A_S' not in res_cat or 'H_A_S4' in res_cat:            continue        y[res_ca...

Yes Jaromil, That`s totally true. Now When I checked NumConstrs- they are also showing me a wrong value  I checked after formulating every constraint : len(constraintname) I dont know somehow the v...

I have used right after .optimize() " you are adding too many variables somewhere"Where is the possibility to check this as if am i adding too many variables or not?

I am checking my number of variables with print(steel.getAttr("NumVars")) It should be 31350 Resources=174*95Tasks=156*95 Instead it is showing: 31680, Is this causing some problem?  

Yes thats right. That is what I have defined in my variables. Resources=steel.addVars(res_list,time,vtype=GRB.INTEGER,name="Resources")Tasks=steel.addVars(task_list,time,vtype= GRB.BINARY,name="Tas...

Hi Jaromil, As Gurobi is completely new to me. Lets do it step by step. 1) To check the Bound section of variables. Let me do this by writing .lp file after defining my variables. This is done: Min...

The feasibility  relaxation gives me the below output: I used this after my optimize function. How to check the new variables added in the constraints?
