Hi Jaromił, With reference to the ideas you gave me, I changed the coefficients of various constraints again. Fortunately, the iterative algorithm can proceed smoothly, but the results do not seem ...

Hi Eli, In a word, thank you very much for your patient reply. You have helped me a lot, thank you! Best regards, Yanbo

Hi Jaromił, Thanks to your guidance, I am getting closer and closer to success. The previous information shows that there may be a problem with the constraint QC2, so I try to decrease the values o...

Hi Jaromił , I put the slack output of the quadratic constraint.  Is it the problem caused by constraint QC2? How can I modify QC2? model.addConstr(l[k, j] * l[k, j] == rhs + s[k][0] ** 2 + s[k...

Hi Jaromił Najman, Sorry, the LP information I provided above may be incorrect. The following is the correct LP file, and I set the boundary of term4.https://www.filemail.com/d/xefvvdrvyudqqtv  I'...

Hi Eli, Thank you for your reply to me. If you have a large constraint violation like this, the solution may not make sense. Feeding a bad solution to the next iteration of your algorithm could de...

Hi Jaromił, Could you provide the second optimization file as well?  This is the LP model after I set MIPGap to 0.006. The reason why I set MIPGap is that in the second optimization process, it i...

Hi Jaromił , After adopting your suggestion, I set the upper and lower bounds for term4. What makes me happy is that after solver obtains the first optimization result, the second optimization can ...

Hi Jaromił, First of all, thank you for your reply! The following is the first optimized. In fact, the second optimization only takes the result of the first optimization as input. This is the link...

Hi, Thank you for your advice. Let me know that I should first solve the problem of max violation warnings and then solve the performance problem of solver.  And then, There are two types of  warni...
