of course, but what about removing constraints, changing variable bounds,
changing the objective?
I don't know exactly. My use of LP is pretty simple : I add constraints
and solve them. Sometimes, I then add constraints and solve them another
time. What I can swear is that I cannot so the following with Coin, and
that they told me it was not supported.
Removing constraints or modifying them is what I consider a "fancy use" of
LP already. I mean, these things are meant to solve sets of equations,
they are not text editors `:-P`
