Thank you very much for your reply. Since the model can be solved after slightly relaxing the right-hand side of the constraints, does this indicate that the reason for the "Numerical trouble encou...

Why do I encounter numerical issues when solving the model?
回答済みI encountered numerical issues while running a second-order cone optimization model, but the model's coefficient statistics seem fine. I have set 'NumericFocus' to 3 and 'BarHomogeneous' to 1, yet ...

Thank you for your reply, when I define a_x and b_x as Mvar the speed of the computation is greatly improved! In my complete code, I used the warning library, which prevented this warning from a...

Why does it take a long time to establish this matrix constraint?
進行中I would like to know why it takes a long time to establish the second-order cone constraint shown in the following code. Here, a_x has dimensions (1, 33), DRCC_cov_load[t] is a (33×33) positive sem...

After making lhs a variable and enforcing this relationship through bounds, the model is no longer classified as non-convex. Thank you very much for your answer!

Why the second-order cone constraint is classified as a non-convex model?
回答済みWhen modeling an optimization problem that includes second-order cone constraints, I found that the model was classified as non-convex due to the second-order cone formulation. The code, .lp file, ...
