Re: Linear Program Optimal Extreme Points

[Michael Hennebry]

My first thought on such a task is to fix all variablee,
structural and otherwise, with nonzero reduced costs.
Unless using exact arithmetic,
that is an interesting task in itself.
Even so, I'd expect it to be better than using
a single linear constraint to implicitly fix them.

A better tactic might be to take a step back
to the reason you want them.
