Why do I encounter numerical issues when solving the model?
AnsweredI 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 ...

Why does it take a long time to establish this matrix constraint?
OngoingI 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...

Why the second-order cone constraint is classified as a non-convex model?
AnsweredWhen 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, ...
