LP solvers are much harder to write. Well, "good" implementations of
an LP solver are more complicated than "good" implementations of a
standard nonlinear local optimizer. The comparison isn't really
apples-to-apples, though. A good LP solver can have much higher
dimensionality than a good nonlinear optimizer will deal with. But
because of this, a typical LP *problem* will also have many more
dimensions, too.
