Problem 8.Let CCR be a closed convex set, and suppose that X₁,..., XKare on the boundary of C. Suppose that for each i, a (x − x₁) = 0 defines a supportinghyperplane for Cat x₁, i.e., C C {x | a (x - x) ≤0}. Consider the two polyhedraPinner = conv{X₁,..., XK}, Pouter = {x|al(x − xi) ≤ 0, i = 1,..., K}.-Show that Pinner CCC Pouter. Draw a picture to explain this.

Ans- To show that $P_{\text{inner}} \subseteq P_{\text{outer}}$, let $x\in P_{\text{inner}}$ be an…

Radio transmitters are located at vl = (0,0), v1 = (2,0), v1 (5, 5). Assume that two transmitters must use different frequencies if and and only if the distance between them is less than or equal to 2r. Let D;(r) be a closed disk, of radius r, centered at vi, and let G, be the intersection graph with vertex set V, = {D1(r), D2(r), D3(r), D4(r)}. Two disks are adjacent if and only if their intersection is not empty. (0, 4), and v4 v3 v4 v1 v2 (a) Shown above are the disks in V2 and the corresponding graph G2. Write down its adjacency matrix for G2, and determine the chromatic number (i.e. the number of frequencies needed). (b) Now suppose the transmitters increase their power levels so that r = 2.5. Draw the new graph G2.5 and determine the number of frequencies needed. (c) Optional extra credit: Use the LaTeX package tikz to plot the disks and the graph.
