WebPROOF CONTINUED • Conversely, if f is polyhedral, its epigraph is a polyhedral and can be represented as the inter-section of a finite collection of closed halfspaces of the form (x,w) aj x+b j ≤ c jw, j =1,...,r, where a j ∈ n, and b j,c j ∈. • Since for any (x,w) ∈ epi(f),wehave(x,w + γ) ∈ epi(f)forallγ ≥ 0,itfollowsthatc j ≥ 0,soby normalizing if necessary, we may ... WebA Cone represents a rational convex polyhedral cone. It need not be full dimensional or may contain a proper linear subspace. It can be zero dimensional, i.e. the origin. It is saved as a hash table which contains the generating rays and the basis of the lineality space of the cone as well as the defining half-spaces and hyperplanes.
