Accessing bounds for a range constraint

[gabe.ha...@gmail.com]

For a range constraint, what can I do to access the lower and upper bound associated with it? The RHS attribute only seems to store one of the bounds. Can both bounds be obtained through some other indirect method?

I should also add that I am using the Python API.

Hi Gabe,

Internally, gurobi represent range constraints with equations with an extra variable (see http://www.gurobi.com/documentation/7.5/refman/py_model_addrange.html)

so, the upper/lower bound information is mixed in the right hand side of the constraint and the bounds of the extra variable.

Best,

Daniel
