We try to return a solution with the _INACCURATE flag whenever the solution might be useful. But our assumption is that most people aren't necessarily checking the status, and returning a terrible solution would break their assumptions about cvxpy.

As CVXPY does not understand semi-continuous variables, we can use binary variables δ ∈ {0,1} and form the constraints: δ⋅min ≤ w ≤ δ⋅max. where we can set max=1. This makes the problem a MIQP (Mixed-Integer Quadratic Programming) problem. This usually means that you ...
