Problem 8.
Let CCR be a closed convex set, and suppose that X₁,..., XK
are on the boundary of C. Suppose that for each i, a (x − x₁) = 0 defines a supporting
hyperplane for Cat x₁, i.e., C C {x | a (x - x) ≤0}. Consider the two polyhedra
Pinner = conv{X₁,..., XK}, Pouter = {x|al(x − xi) ≤ 0, i = 1,..., K}.
