Dear all, I encountered error says model is unbounded. The model is formulated as a MIP minimization problem. I wonder how to debug the unbounded issues. Are there any function calls could help lik...

Hi, Recently, i set up a model in Gurobi. It shows that the model is infeasible. In order to troubleshoot the error. I hope to use the following codes to generate the ilp file : m.computeIIS()m.wri...

Hi,  Recently, i had this issue when i added a constraints statement : ~\AppData\Local\Temp/ipykernel_18284/4133350432.py in <module>     34 m.addConstrs((T5[i] + Px <= T2[j] + (1-s[i,j,g])*M for i...

Hi, I  created a python loop to solve a model with gurobi iteratively. In each iteration, i just change different parameters. However, sometimes, the new parameters will cause the model infeasible....

Based on the results x[8,3,R1] = 1, Ti_1[3] =22, Ti_2[8] = 34. But it valid the the highlighted constraint. i don't know why it allows the results...???  

Hi, I got the following output when i run my program: No HostID specified in license file I added the system variables for the license file. But it remains the same. Please help to suggest!
