Let's have the following trivial linear program: \begin{align}\max&\quad z=20A+30B\\\text{s.t.}&\quad A\le60\\&\quad B\le50\\&\quad A+2B\ge220\\&\quad A,B\ge0\end{align}
It's easy to spot that the first three constraints are contradictory. So, there are no solutions.
Let's assume we have dozens, hundreds, or even thousands of variables and constraints. Is there any automatic way to spot the contradictory constraints? Maybe by some nuance of AI?
