SCIP not detecting symmetry in MINLP

[Joao-Dionisio]

I have a simple model that has obvious symmetry. Solving the model for whatever number of Power Transformers, should be no more difficult than solving the model for just one, as the solution of one can be copied to the others. SCIP does not detect symmetry in this MINLP.

These are the variables:

These are the constraints:

For PTs = [1,2,3] (so, for 3 Power Transformers), we get the following message:

If we solve the model for 1 Power Transformer, we get this result:

For 3 Power Transformers, we get this:

Notice that the solution for 3 Transformers is 3 times the solution for 1, as it should be. (The variables are also the same) You can find the code here: not_detecting_symmetry.zip
