We first define a geometric entity that will correspond to the notion of
a corner point for any dimension. Recall that in two dimensions, a corner
point of a feasible set P of a linear program should not lie in the interior of
P and should not lie in the interior of any line segment on the edge of P . A
mathematical representation of this requirement is embodied in the definition
of an extreme point. First, we need the following.
