It's a bit confusing at the moment because in the install script at https://install.julialang.org, it says `Unable to run interactively. Run with -y to accept defaults, --help for additional options`...

Here is another case where it would be useful to know the type of the variable. Cbc also has issues when the variables are not binary in a SOS constraint:...

Yes, I would say you would need at least the length of a standard talk

I think doing this would in fact decrease complexity quite a lot. Maintaining this MOI layer and simpler NL solver is much easier than maintaining MOI wrappers that are so...

Do you know a solver which could take advantage of knowing the matrix structure ?

Is Gurobi actually using this matrix or is it just transforming it and for the algorithm it won't change anything whether you give this matrix or a VectorAffineFunction ? Is...
