Hello Griffin,   the bloat you are observing comes from the exponentially growing size of the symbolic representations of the linear expressions. Looking at your the example code (modified for brev...

The syntax you are using is very reasonable, but unfortunately the expression y*y, which I would interpret as a quadratic expression of shape (5,), is not yet supported by gurobipy (all quadratic e...

It is correct that you cannot directly pass such matrix based data to gurobipy, so that you need another "conversion" step from this data to the modeling objects within gurobipy.  What data structu...

It seems that currently, it's only possible to add a quadcon one-by-one in a loop. This is effective only for small problemsWhat is the time you'd need to call it effective?  Here is a simple exper...

Christian, in all versions 10.0.* and 11.0.0 you can use a list of strings as the 'name' argument for Model.addMConstr to give individual names per constraint. That's in line with the docstring of ...

Gurobi's barrier algorithms all follow the general predictor-corrector scheme, and any complexity bound on the number of Newton steps from an delta neighborhood of the central path to an epsilon ne...

Our package has some user-submitted code that depends upon  functions deprecated or removed by gurobipy 10.x   Maybe a better approach would be to adjust your code then?  Can you point me at the ...

That said, the workaround should no longer be necessary starting in the next feature release after 9.1, where you will be able to just do m.chgCoeff(c[0], x[0], 5) This works because indexing an MV...

Hello José, unfortunately there isn't a shorthand for doing this in gurobipy yet, but I have taken note of your feature request in our development backlog.   For now you will have to model the abso...

Hello Jonathan, as written by Eli there currently is no way to change coefficents w.r.t. an Mvar object, but I have registered this in our backlog of future improvements to the matrix-friendly API....
