Hi Jaromił, Thank you again for your help and detailed reply.   it is currently not possible in Gurobi to reformulate the function f(x)=log(1+1x)f(x)=log⁡(1+1x) in a way that the model remains con...

Hi  Jaromił, With your help, I have solved most of the problems I have encountered before. Thank you very much. Nonlinear equality constraint, such as z1⋅z2=100 already define a nonconvex set. I ...

Hi Jaromił,  Due to some personal reasons, I'm sorry to reply to you for so few days llate. How do you make sure that your algorithm converges to the correct global maximum?  In introducing this ...

Moreover, I found that in the calculation process, there will always be warnings about the following restrictions. Is there a better way to express the relationship between decision variables q and...

This is the code of CVX. import cvxpy as cpimport numpy as npimport mathK = 4s = np.array([[-150, -150, 0], [-150, 150, 0], [150, -150, 0], [150, 150, 0]])R_r = 0def cvx_demo(ipc): ir = [None] *...

Hi, Jaromił After several days of debugging, although I can get a result through the model, I have different results when I split the model and calculate separately, which leads me to doubt the cor...

Hi Alison， Okay! Thank you very much for your help! Best regards, Yanbo

Hi Jaromił, I set FeasibilityTol  to 1-e8. As you think, the tolerance violation warning still exists, but the quality of the solution has been improved. But there is also the problem that the opti...

Hi Jaromił, After several days of debugging, I have made great progress with your help. The following is a supplement to my previous answer.  The first is the version of gurobi I use.  And then, I...

Hi Jaromił, Maybe I didn't express it clearly. I mean that the last iteration process can converge to get the final result of the current iteration, but the whole iterative algorithm is not converg...
